I have the following dataframe: df <- data.frame(ID=1:3, col1=1:3, col2=4:6, col3=7:9, col4=10:12, col5=13:15, col6=16:18, col7=19:21) I need to create a function that essentially does the following: df_new <- df %>% select(ID, c(col1:col5)) %>% mutate(col1=col1/col2, col3=col3/col2, col4=-col4, col5=-col5) With the result: > df_new ID col1 col2 col3 col4 col5 1 1 0.25 4 1.75 -10 -13 2 2 0.40 5 1.60 -11 -14 3 3 0.50 6 1.50 -12 -15 I write a function to do this: genUIR_test = function(df, arg1, arg2, arg3, arg4, arg5){ arg1 <- substitute(arg1) arg2 <- substitute(arg2) arg3 <- substitute(arg3) arg4 <- substitute(arg4) arg5 <- substitute(arg5) df_new = df %>% select(ID, c(arg1:arg5)) %>% mutate(arg1=arg1/arg2, arg3=arg3/arg2, arg4=-arg4, arg5=-arg5) return(df_new) } And when

I am trying to populate a raize combobox using the following code: ''' Procedure RefreshCB(); begin SPDBForm.SPDB.Connected := True; try SPDBForm.SPQ.Close; SPDBForm.SPQ.SQL.clear; SPDBForm.SPQ.SQL.Text := 'SELECT * FROM Contacts'; SPDBForm.SPQ.Open; SPCRMAddClientForm.SPSubCB.Clear; Try SPDBForm.SPQ.First; Try SPCRMAddClientForm.SPSubCB.Items.BeginUpdate; while not SPDBForm.SPQ.Eof do Begin SPCRMAddClientForm.SPSubCB.items.Add(SPDBForm.SPQ.FieldByName('CompanyName').AsString); SPDBForm.SPQ.Next; End; Finally SPCRMAddClientForm.SPSubCB.Items.EndUpdate; End; Finally SPDBForm.SPQ.Close; End; finally SPDBForm.SPDB.Connected := False; end; ''' What I end up with is several blank lines except for the last one which po

I am running the ArchivesSpace 4.1.1 application that has bundled ruby files. When I attempt to visit the public user interface, I get the following two errors. I know very little about Ruby and since the files are bundled with the application installation I am hesitant to uninstall or install anything that might cause further issues. Any thoughts on what might be causing these two issues?

So I was told by project collaborator to access to a specific subdirectory under a path. Entering the very path I found ls -l gives nothing listed and the disk usage is 0, same for du -h. Nevertheless, I surprisingly found I can actually cd ./foo into the subdirectory deemed to be there by my collaborator. I wonder what is the mechanism that does it? Is it counterpart of MS Windows’s hidden files to Linux? How to set it?

I have a web application developed in flutter in the folder /app. I would like to install Wordpress on to host all the regular content pages. However, when a user interacts with the /app pages, Wordpress interferes and throws a Page not Found error. The suggested "solution" places the app in an iFrame, which creates its own issues. Therefore, I am trying to exclude the /app sub folder from WP processing.

I'm coding a chess AI and for that you need a way to count the pieces to figure out how good a position is. And when I tested my method that counts the pieces I noticed it was a little slow so I tested it part by part to see what was taking so long and I found something extremely strange. For the piece of code I have written below when I run 7 or less out of the 10 lines of code it runs extremely quickly only about 10 milli seconds to run 100 million times. But when I run all 10 lines of code it takes a whole 1000 milli seconds to run 100 million times, that's a 100x slowdown when I run the full thing. And it does not matter which 3 lines I eliminate to speed it up, I have tried many permutations and as long as I have 7 or less of the 10 lines it goes fast and if I have more than 7 it goes slow every time. I asked chatGPT and it told me it was JIT optimizations that was causing the fluctuations but that does not make any sense because the way I made my speed test I added up the tota

dailySalesSummaryArw_(retailernumber)_(DateYearMonthday) I have files in a windows folder with this naming convention: 0682241_Daily_Sales_Summary_5-24-2025 I can change the file manually, but there are over 100+ files and I think a windows batch script (because I do not have any other options) so a user can run it and it will rename the files to the following naming convention: dailySalesSummaryArw_0682241_20250524.csv The number of underscores in the original file are set. However, the example value of '0682241' will be different for other files but will always be 7 characters in length. I've searched google but don't know enough to put one of these together. Does anybody have any suggestions?

For a questionnaire in LimeSurvey v6 I need to implement a two-part question. In question 1 the respondent should be able to enter the name of organizations they work with, one per row. Ideally the respondent can add as many rows as needed, dynamically. Each row contains just a text field for the name of the organization. In question 2 I want to display a matrix where each row corresponds to one organization entered in the previous question. There are three columns representing a Likert-type scale from 1 to 7 to assess different aspects (importance, influence, current collaboration). I used a "Multiple short text" question type in Question 1 with predefined sub-questions and JavaScript to reveal more fields with a button (up to 10 rows). In Question 2 I created an "Array (Numbers)" question and used {question1_SQ001} to {question1_SQ010} as sub-question texts. I used JavaScript in Question 2 to hide rows where the co
