I am seeing very strange behaviour in R 3.2.0 patched (r68272) and a new
build of R-devel. The sessioninfo() from the former is below.
Here's what I see: If I set the locale, and trigger a namespace load, a
version comparison gives NA, and I get an error. For example, in a new
session started with R --vanilla from the terminal:
> Sys.setlocale(locale='en_US.UTF-8');grid::gpar()
[1] "en_US.UTF-8/en_US.UTF-8/en_US.UTF-8/C/en_US.UTF-8/en_CA.UTF-8"
Error in if (R_version_built_under < "3.0.0") stop(gettextf("package %s
was built before R 3.0.0: please re-install it", :
missing value where TRUE/FALSE needed
I've tried debugging this, and the bad lines are these, in loadNamespace:
R_version_built_under <- as.numeric_version(built$R)
if (R_version_built_under < "3.0.0") stop(gettextf("package %s was built
before R 3.0.0: please re-install it",
sQuote(basename(pkgpath))), call. = FALSE, domain = NA)
These are in the src/library/base/R/namespace.R file, around line 379.
If I stop it before the if and evaluate R_version_built_under, it looks
fine. If I stop it there and evaluate
R_version_built_under < "3.0.0"
I get NA. If I evaluate it again without changing anything, I get FALSE.
Does anyone else see this? Any ideas on what might be the cause?
