[R] Ghost variables

[Jeff Newmiller]

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.
