R help - Jan 2025 - R CMD check says no visible binding for global variable

Hi Naresh Gurbuxani,

There are already several answers dealing with the specific code that you wrote,
but my reaction is to step back a little.

R CMD ? starts an R session but takes standard input from a file. (In Unix-like
systems you might even be able to make an R script into an executable file.) I
think it even uses the same .Rprofile as a regular R session. If there is a
problem, you can paste the code a few lines at a time into a new ordinary R
session. Then you can also set breakpoints (using debug, trace, or similar) in
whatever functions you think caused the problem. You could also wrap all the
code in a function and use the debugger to step through that (which may help if
the error occurs in an iteration of a loop body).

Regards,
Jorgen Harmse.

Subject: [R] R CMD check says no visible binding for global variable

I have written a function which returns an SQL query result as a data.frame. 
Each column of data.frame is a variable not explicitly defined.

For every column name, R CMD check says ?no visible binding for global variable
<name>. Status: 1 NOTE

Is it possible to tell R CMD check that these variables are OK?

Thanks,
Naresh
