[Redirected from R-Devel...] Not that I recall running across such, but does R (or CRAN package) provide something equivalent to PHP's escapeshellcmd() function to escape shell job control, wildcards, etc?
I don't know PHP, but what does escapeshellcmd() provide over and above what system() / system2() do?
As before, it escapes job control, etc from the command string.
Assuming such existed in R, it would be used something like this:
R> system(escapeshellcmd(sprintf("somecmd %s", untrustedInput1)))
