I'm reading tables from a website where one of the columns is university name and some of the names have special characters which are the following (but the names are written like I put them here, so is not a task I can fix by reading the web in a different way):
...ANSWER
Answered 2021-Mar-30 at 12:26As Deceze has commented, if the data is corrupted at source there is no guarantee that you can undo the corruption. However, using the data you provided we can make some progress.
Firstly, the vast majority of the strings in your list can be fixed by encoding as latin-1 and then decoding as UTF-8.
QUESTION
I'm trying to use yfinance to pull option chains per stock from a list of tickers and for all the available expirations per ticker.
So my code should loop over each ticker, get expiration dates, loop over each date, get options chain, then jump to next ticker and repeat.
The code below sometimes works fine, but not always, and especially as I add tickers it seems like variables get reassigned on each loop? - For example, by the time it gets to RKT the expiration dates for RKT look nothing like its actual expirations dates. It may happen on the first tickers or towards the end, or randomly, but there's always some tickers with wrong expirations, especially as the list grows.
This is my first go at it and tried to use similar examples to debug, but nothing worked or I wasn't applying them correctly.
...ANSWER
Answered 2021-Mar-19 at 01:31I can't find anything wrong with your code - it kind of seems like the data from that endpoint is changing, which is why you're getting different results from each request.
I can offer an alternative solution though (it's a bit faster and much easier to implement). It's a package called yahooquery. Disclaimer: I'm the author of the package.

I have seen the post in here : https://github.com/tidyverse/dplyr/issues/3101 and tried to work with summarise_at, however it doesn't work with 3 functions, instead I found simpler with summarise_all. Is there any way to reduce the inner join from my code?

QUESTION
I am trying to loop by grouping data with dynamic group parameter.
We can use dynamic queries on WHERE conditions on loops but I do not know whether it is possible to use a dynamic string in group condition.
Here is the sample where user decides by which field to group and then put additional logic based on the decision:
...ANSWER
Answered 2020-Jul-20 at 15:51As pointed out in the comments, LOOP AT ... GROUP BY doesn't support dynamic group-by clauses from strings.
In this simple example you could create your grouping key dynamically at runtime by creating it with an inline expression like COND or SWITCH:
QUESTION
I am using SAP GUI 7.50 and running the script from Excel. I recorded a script for transaction ZC9_SE16_MAT table MARA. I want to select multiple material numbers, but pressing the button with the recorded script is ignored (does not open new window). The button is marked in the image. How can I open that window?
...ANSWER
Answered 2020-Nov-24 at 11:25I found a solution for my problem, but is not perfect. Press Shift + F11, which turns Technical View On. Then there appears option Ctrl + F9, which open window Multiple Entry. This new window looks very similar to the first window, but now recorded press on the button works.
This solved my problem, but I would still like to know how to pres on the first button so if anyone knows please add answer.
QUESTION
The code below produces the left block of data
It gives me the entire subset however I only need to see: For the same SATNR-VKORG combination where ALL Variant_Status is I2. If any of the Variant_Status is NOT I2, then do not show the entire SATNR-VKORG combination. My final output should only be the first two lines in the data below whereas all the other rows do not qualify.
I can't figure out how to do this but I'm thinking to use a count function like the right block to concat the SATNR-VKORG and SATNR-VKORG-Variant_Status and do a count of each unique combination. For the same SATNR-VKORG combination, if the two counts are identical then that means display else do not show. Even that I don't know how to code it, anyone help or have any better idea?
