Full_Name: Michael W. Grant
Version: 1.7.1(2003-06-16)
OS: Windows 98 Second Edition 4.10.2222 A
Submission from: (NULL) (24.55.165.101)


I just installed version 1.7.1 tonight. In the process I installed via CRAN from
the menu several packages. One installation, exactRankTests, had a distinct
anomaly. A DLL attempt to change FPU control word as seem in the last line  of
the following listing:

START LISTING:
>
install.packages(choose.files('',filters=Filters[c('zip','All'),]),
.libPaths()[1], CRAN = NULL)
> local({a <- CRAN.packages()
+ install.packages(select.list(a[,1],,TRUE), .libPaths()[1], available=a)})

END LISTING


NOTEs
1.) this installation was done immediately after starting Rgui, i.e., Rgui was
launched, "Packages" dropdown clicked, "Install packages from
CRAN..." clicked

2.) subsequently several other packages installed without incident.

3.) R was killed, restarted, and the installation done again and the same
DLL/FPU anomaly occurred.

Best regards

That is not likely a bug in R, it's a bug in some other software on
your system, which has changed the floating point precision.  It's
hard to track down exactly what program did this, and hard to fix.
The general strategy for tracking it down is to find the minimal
operation that does it (e.g. does it depend on which package you
install?  Do you get it from a local install instead of a remote
download + install, etc.)

If you set options(warn.FPU=TRUE) then you'll see the warning more
often; without that option, it is suppressed.
