Could R CMD check be using valgrind to run the examples? Valgrind has
to interpret CPU instructions manually to be able to warn about
results of code execution depending on memory values it considers
undefined, so it is much slower than execution on a real CPU.
One way to verify that on a GNU/Linux system would be to temporary
insert system('pstree -aps $$') into one of the examples and look at
the output produced.
Thanks for the suggestion. I put the command that you advise in the
first example that gets run and in the file
ldEst.Rcheck/ldEst-Ex.Rout
I got the output:
system('pstree -aps $$')
systemd,1 --system --deserialize 32
`-lightdm,1249
`-lightdm,1568 --session-child 13 20
`-mate-session,1595
`-mate-panel,1772
`-mate-terminal,16032
`-tcsh,18036
`-sh,18204 /usr/lib/R/bin/check ldEst_2.0-15.tar.gz
`-R,18208 --no-restore --slave --args nextArgldEst_2.0-15.tar.gz
`-sh,18572 -c ...
`-R,18573 --vanilla
`-sh,18579 -c pstree -aps $$
`-pstree,18580 -aps 18579
Nothing untoward leaps out at me. Certainly no mention of valgrind. Can anyone see anything in the foregoing output that I should investigate? Ta. cheers, Rolf
