Hello!
with the R system command I would like to call a perl script which needs an
input directory and an output directory in form of a path. When I put in the
path directly it works. The script line looks as follows:
system("perl '../path1' '../path2' '../path3'")
If I store the path in a variable/object and call the perl script again it
does not run and I don't know how to overcome that issue.
p1 <- "../path1"
p2 <- "../path2"
p3 <- "../path3"
system("perl p1 p2 p3")
I also tried:
system("perl 'p1' 'p2' 'p3'")
Can anyone help?
Best,
syrvn
