qw Takes an unquoted vector and adds quotes to it like the qw function in perl.
qw
qw(...)
Any unquoted strings
A vector
This is a helper function for data processing. Honestly, I use qw all the time in other languages, and wanted a version for R.
# NOT RUN { c("a", "b") qw(a, b) # qw - a helper function that we # will use later to deal with strings # analagous to qw in PERL # }
