Ghost variables
Some other points: A) I have seen these kinds of warnings in RStudio related to Rmd files. Try running your script in R rather than using RStudio, at least to identify where the problem is. If they are being generated by RStudio then you need to get help through their recommended forum. B) Check for and remove any ".RData" file in your working directory when you start R. That is, if there is no text before the period in that file name it will get loaded automatically when you start R and any problems that were saved into it will be restored into your global environment. I recommend deleting such files, or at least renaming it so it won't get automatically reloaded. C) Your assertion that the script is complete are only as trustworthy as allowed by your skills to confirm that. Pardon us if we reserve judgement on that point until the problem is isolated.

The warnings are issued for these "ghost" variables well before they
are
created later in the script.
Somehow previous incarnations are lingering around and being unhappy
even
after they were "deleted".
Jeff Newmiller has suggested a solution I have yet to try.

Re: [R] Ghost variables
Doesn't that mean that your script is incomplete, that it needs to make
those variables?

Fellow R-gonauts:
I frequently erase/remove all the objects in my current environment so

I re-run scripts to ensure that analyses are complete, error-free, and
accurate.
However, sometimes when I re-rerun a script I get warning messages (see
below for example) regarding some variables (objects) when these
variables do not exist in my current environment.
These ghost variables had existed at one time, but were subsequently
removed by the rm(list=ls()) command or by the broom icon in RStudio.
What's happening and how do I exorcise the ghosts?
