Inconsistent rank in qr()

For a me a "full rank matrix" is a matrix the rank of which is indeed min(nrow(A), ncol(A)) but here the meaning of "always is full rank" is somewhat confusing. Does it

stats::line() does not produce correct Tukey line when n mod 6 is 2 or 3
A usually trustworthy R correspondent posted a pure R implementation on SO at some point in his lost youth: https://stackoverflow.com/questions/3224731/john-tukey-median-median-or-resistant-line-statistical-test-for-r-and-line This one does indeed generate the line of identity for the (1:9, 1:9) case, so I do suspect that we have a genuine scr*wup in line().

Bug report: Function ppois(0:20, lambda=0.9) does not generate a non-decreasing result.
function ppois is a function calculate the CDF of Poisson distribution, it should generate a non-decreasing result, but what I got is: > any(diff(ppois(0:19,lambda=0.9))<0) [1] TRUE Actually, > ppois(19,lambda=0.9)<ppois(18,lambda=0.9) [1] TRUE Which could not be TRUE.

Inconsistent rank in qr()
Hi, I have noticed different rank values calculated by qr() depending on LAPACK parameter. When it is FALSE (default) a true rank is estimated and returned. Unfortunately, when LAPACK is set to TRUE, the min(nrow(A), ncol(A)) is returned which is only occasionally a true rank. Would not it be more consistent to replace the rank in the latter case by something based on the following pseudo code ?

Problem with R using pgi compiler on x86_64
Hi, we have installed R-2.8.1 using the current pgi compiler (8.0.2) for AMD64 on a SLES9 system. When I try to install "Matrix" everything is fine until the last step. make[1]: Leaving directory `/tmp/R.INSTALL.TW3399/Matrix/src/AMD' pgCC -L/usr/lib64 -L/usr/X11R6/lib64 -pgf90libs -o Matrix.so CHMfactor.o Csparse.o TMatrix_as.o Tsparse.o init.o Mutils.o chm_common.o

Install package 'Matrix' problem
64-bit R-2.12.0 was installed on Sun SPARC Solaris 10. Compiler used is solstudio12.2. Attached is the configure script. I then tried to install a recommended package called Matrix.

R-devel/Linux x64/Sun Studio 12: Problem with Matrix
Dear Developers, motivated by the new Sun Studio checks I compiled R-devel and several of our packages with Sun Studio 12 on Fedora x64. Everything worked fine and R-devel runs, with the exception of package Matrix where compilation crashes with the following message. The error occurs during building of the recommended packages and also if Matrix is compiled separately: [...] CC -G -lCstd

[New Patch] Fix disk corruption when writing
I tried the newest patch, but it does not seem to work for me (on Linux). Despite the check in Rconn_printf, the write.csv happily writes to /dev/full and does not report an error. When I added a printf("%d\n", res); to the Rconn_printf() definition, I see only positive values returned by the vfprintf call. Cheers, j. On 4 July 2017 at 21:37, Duncan Murdoch <murdoch.duncan at

This doesn't work, because 1. all.equal does *not* return FALSE. Use of isTRUE or identical(., TRUE) is required if you want a boolean. 2. all.equal compares two objects, not elements in a vector.

Compiling Matrix on Solaris 10 x86-64 Sun Studio 12
Hi all, I have trouble to compile Matrix packages on Solar10 x86-64 with Sun compilers. I saw some postings on this but am not sure how to solve this problem. It is becoming critical as I cannot install biocLite() because of its dependency on Matrix. Could you direct me how to resolve the issue? Thanks in advance!
