Hi, I need a Python programmer who know Pandas. I have a half completed script which requires two dataframes to be combined and thats all. Firstly I need the developer to complete the script. Then secondly id like the developer to advise on the best approach to display the results of the dataframe in the most simple python web app.

...block. Below the title space, data will be displayed ("data block") in one of the following formats: a scatter plot, bar chart, pie chart, heatmap, table. --- Key Functions --- These are functions that will be implemented for the data pipeline moving data from a CSV to a displayed page (for each displayed page). - Read file to dataframe function: I should be able to take data from a csv into a pandas dataframe - Manipulate dataframe function: Take that raw dataframe and do some basic manipulation to produce a "clean panda." - Display function: Take the clean panda, input it into a function that displays the data Input the panda to a function that displays --- Examples --- 1: See attachment for a rough sketch of the two key temp...

I merely want scraped into a pandas dataframe

Hi there, The idea is to change the existing python code to improve the performance of the calculations of time variations like ytd, qtd etc... There are multiple way to do that, someone suggested using ordered dict or a dataframe (Pandas). I let it up to your expertise. I need you to change how the Postgres piece is calculating the time variations because the way It is done now isn’t really good from a performance perspective: Example 1: I am calculating week to date by aggregating every single date and then adding the 7 days together. What I want is to store the previous 6 days and only add the latest in the series (One day). Example 2: We are at day 3 of the week, now I am adding up the three days every time. I want you to change the code so that the first 2 ...

Hi there! I need to change some existing python code I wrote to better calculate some time variations like ytd, qtd excetera. The data is in postgres Someone suggested using ordered dict instead but I was wondering if time calculations would better be handled by a dataframe (pandas) or the dictionary approach I was suggested. I will leave that up to your expertise.... You may find attached the code I am referring to as well as the sample output Let me know if you have any question, F

Like to have a function that turns a pandas dataframe into an HTML table but unlike the default .to_html() function, allows to have Excel style color scales conditional formatting eg like in Note that the HTML code will be emailed so you are restricted to standard HTML that can be rendered by Outlook/gmail etc! function call: df_html(dataframe,[col_names_to_be_colored]) return value: HTML code So say I have a dataframe like the one below, I'd like to call df_html(data_in,['Spread']) to get formatted HTML code such that the 'Spread' column is colored as shown above. data_in={'Ticker':['A','A','A','B','B','B'], 'Date':['1/1/05&#...

Hi! We need .net C# class that communicates with R (statistical package). The class should contain methods that convert DataTable to R DataFrame and backwords, and method that has an input as DataTable and R command(string) and returns DataTable. Method should convert DataTable to NumericMatrix object, execute command in R, collect result (DataFrame) and convert to DataTable. All can be done using open source library. Best

I have a pandas dataframe with 2 columns : transaction_date (datetime), days_waited (integer) I would like to draw a boxplot to represent the distribution of the days_waited values grouped by each month or week. ie. yaxis = days_waited, xaxis = month (xtick format like 'Oct 2014'), or week (xtick format like 'w41 2014').

I am looking for a way to create rolling windows (aka sliding windows) of variable size, making the window of the rolling computation to be defined by a range of values of a column of the DataFrame, and not by the number of rows in the window. I also need to customize the step of the window (the starting point of the next window) so that again it is defined by a range of values of the same column (not longer defined by a number of rows). Finally for each window I have to compute the average values of the other columns.

The objective of this small project is to create a ArcGIS AddIn that renders a toolbar that allows the user to change their dataframe coordinate system to one of the logged in users "Favorite" Projections or Geographic Coordinate Systems. The Addin Must be Compatible with ArcGIS 10.x and be signed. The AddIn should be useable standalone or supported by server rollout. NOTES ABOUT DEVELOPMENT The ArcGIS 10, add-ins is to be authored using .NET with Extensible Markup Language (XML). The XML describes the customizations, while the .NET classes provide the custom behavior. The ArcObjects software development kit (SDK) includes an Add-Ins Wizard that integrates with development environments using Microsoft Visual Studio 2013. Source Code and Project to be supplied.

Objective: to augment data given by applying additional data transformations We have two files which have been split into A and B. The only difference is that one of the columns in B is not filled in (this is by design). We are interested in applying 26 additional transformations to the data. They are as follows: TAN COS SIN PROBABILITY MASS FUNCTION SQUARING OF VALUE X MULTI...3+) to complete the task. This code should be well documented. Also it should be written to injest data which expands or contracts. For example, the dataset today may have core elements of 20 data columns and in two months it may shrink to 7. We will need to be able to modify the code in such a way to adjust for such considerations. We believe that this can be accomplished by augmenting a data...

...in R. I have one method of analysing sentiment, shown below, however I am open to ideas on how to improve the method. Attached are 3 files: JSON – the JSON file containing the tweets – a lexicon of positive words – a lexicon of negative words Please provide an R script which: 1. Imports the tweets in the JSON file into R as a dataframe 2. Identifies the tweets themselves (the $body field in the JSON file) 3. Allows sentiment analysis in the form demonstrated below, or an improved form of your choosing 4. Is useable in real time with a live JSON stream as well as the static file attached Additionally, please provide workspace images showing the result of the script. Thank you very much in advance!

...tagged C programming because R was not available, and most C programmers know R, I guess. My apologies if this is misleading. Having said that, if someone wants to carry this out in C with an R frontend, you are welcome. The function should take an lm-object and the name of a cluster variable as input (the cluster variable will be in the dataframe used that is stored in the lm-object. Would be cool if it was automatically retrieved from the dataframe stored in the lm-object), and computes wild-t boostrapped p-values for the regression coefficients. I will provide references for the method but it's simple: re-estimate leaving the regressor of interest out, take those residuals, multiply with 1 or -1, add to predicted dependend variable, re-estimate with regressor o...

...gov/wildlife/waterfowl/shoot/13/ The module should be able to scrape a range of these weekly reports into one data frame. The output should be in the form of a Pandas dataframe. The row index should be a multiindex with area name and date. The remaining fields should be columns. A basic example of the input and resulting output are attached. I would like to be able to use the module in the following ways (where ‘dfg’ is the module you will write): >>> df = (start_year=2012, start_week=3) # returns a dataframe with all data starting from 2012, week 3 through present. >>> df = () # returns a dataframe with all data published.

...almacene en un DataFrame cuya versión acumulada se envíe después de cada extracción en formato csv o excel. Por ejemplo, los rangos horarios podrían ser de 9 a 10, de 13 a 14, y de 16 a 17, y dentro de esos rangos que la hora exacta fuera aleatoria. También habria que ver de establecer que esas conexiones fueran desde IPs distintas. Las páginas son las siguientes: En cada una, habría que ir a la pestaña 'Prices/Quotes'. En esta pestaña hay una serie de botones que cambian la duración o el vencimiento de la opción. Para cada una de estas posibilidades hay que recoger toda la serie de datos e incorporarla al DataFrame general

I will have pdf files with reports of market commentary. I need a dataframe that finds in the pdf file only the relevant text blocks (not the dates, emails, page nr, etc etc). The data frame should have the date, the bank who wrote it, the analyst name, contact email, and then the string of text. As a secondary version, I want to pdf files by paragraphs (so not the entire text block but several blocks per day it was written). I want to do topic modelling and find the relevant paragraphs per topic. and lastly, the entire set decomposed into individual phrases, so I can run analysis on all the phrases. I put an example so you can get a better understanding. I'll put all these pdf files in one folder and the tool should go through it and put the text blocks into a data frame. ...
