Hello dear R-devel,
When installing R 3.0.0 on Windows 7, and then running:
require(tools)
checkMD5sums(dir=R.home())
I get the following massage:
files ‘etc/Rconsole’, ‘etc/Rprofile.site’ have the wrong MD5
checksums
[1] FALSE
Rprofile.site is likely to be changed when you install R. It's pretty easy
to change Rconsole as well.
So perhaps the bug is that we are running checksums on those at all.
Maybe this is what you just implied/said, but if the MD5 checksums are
calculated on files with '\n' line breaks (on the build server) and
then they are simply rewritten "as-is" upon installation (but with
'\n' translated to '\r\n'). This could happen if they are written
using cat() or writeLines(), which writes using text-mode connections
and therefore have all '\n' translated to '\r\n' on Windows, e.g. (on
Windows):
cat("a\nb", file="foo.txt"); file.info("foo.txt")$size
[1] 4
cat("a\rb", file="foo.txt"); file.info("foo.txt")$size
[1] 3
cat("a\r\nb", file="foo.txt"); file.info("foo.txt")$size
[1] 5
writeChar("a\nb", eos=NULL, con="foo.txt"); file.info("foo.txt")$size
[1] 3
I've been bitten by '\n' -> '\r\n' so many times (e.g. can cause
unnecessary SVN commits/updates). Out of curiosity, as of 2013, are
there any good reasons for generating '\r\n' - what Windows software
does not handle '\n' these days?
Inno Setup: the installer software!

This happens when using the 32 and the 64 bit version of R.
And was also reported by 2 other users on other machines, as can be seen
in
the comments to this post:
http://www.r-statistics.com/2013/04/r-3-0-0-is-released-whats-new-and-how-to-upgrade/
The R version was downloaded from this mirror:
http://cran.rstudio.com/bin/windows/base/
And installed on both the C and D drive on different computers (to
rule-out
any permission issues during installation).
I hope I didn't miss anything,
Tal
