Dear Peter,
It actually breaks install.packages(). So it is not that innocent.
And hence, as Peter exoplained, it is already fixed inn R-patched,
thanks to Tomas Kalibera.
Best,

Yes, we noticed this in the last days of the code freeze before
release and
shied away from inserting a workaround, partly because we
couldn't see what
the root of the problem might be.
For the purposes of installed.packages it is relatively harmless
to treat
the NA condition as FALSE, since it is just a matter of whether
a cache is
valid. I.e., it might cause an unnecessary cache rebuild. For other
situations it might be more of an issue.
The workaround (NA -> FALSE, basically) is in place in R-patched and
R-devel.

Hello,
I am currently getting a strange error when I call
installed.packages():
Error in if (file.exists(dest) && file.mtime(dest) >
file.mtime(lib) && :
missing value where TRUE/FALSE needed
Calls: installed.packages
I am working with R 3.4.0 on Windows. I didn't get this
error with R
3.3.3.
Apparently, file.mtime() is returning NA well applied to a
directory, and
this causes the entire && expression to be NA, then the "if"
fails because
it needs either T or F.
The source of "installed.packages" seems to be roughly the
same as in R
3.3.3, so I wonder if there have been other changes in R,
maybe the
logical
operators, that would make this function fail.
Any idea?
Best regards,
Jean-Claude Arbaut
