call to system returns warning : status 2 (Ubuntu)
...call the external program.
basically, in my script I have inside a loop these two lines:
command <- paste(<some constant or variable strings>,sep="")
system(command,intern=T,wait=T)
when I run this script, I get a number of warnings,
like this one:
16: running command '~/LDhat22/ldconvert -seq ld/serca/serca-Trs.fas
-freqcut 0.0 -missfreqcut 100.0 -sites 1 3687 -nous 6 >
ld/serca/serca-Trs.out' had status 2
however, when I run the very same command at the bash prompt,
everything seems fine (no complaint).
in either cases, the output is the same and looks correct....
