qw Takes an unquoted vector and adds quotes to it like the qw function in perl.
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.
c("a", "b")
#> [1] "a" "b"
qw(a, b)
#> [1] "a" "b"
# qw - a helper function that we
# will use later to deal with strings
# analagous to qw in PERL
