[R] Why Rscript behaves strangely with file name starting with 'size'?
Hello All, It seems weird to me that Rscript does the following thing and enters the R prompt mode. If I change the file name to something that doesn't start with 'size', then Rscript runs normally. Does anybody know what is going on? $ Rscript size.R WARNING: '--file=size.R' value is invalid: ignored>$ Rscript --version R scripting front-end version 51072 -- Tom

It looks like a bug in R, not Rscript: what Rscript does is effectively
R --file=size.R
and you can easily test that
echo 'print("Hello world")'> size.R
R --file=size.R
give you the error while
cp size.R asize.R
R --file=asize.R
works as expected.
None of which helps you directly, but perhaps one of the developeRs can
help fix what seems to be broken options parsing in the R code.
