This is on r-devel from 2005-03-15. iconvlist() uses (at least some of
the time)
icfile <- system.file("iconvlist", package = "utils")
which looks like
"""
The following list contain all the coded character sets known. This
does not necessarily mean that all combinations of these names can be
used for the FROM and TO command line parameters. One coded character
set can be listed with several different names (aliases).
437//
500//
.
.
.
"""
which leads to
> tail(iconvlist(), n = 40)
[1] "WS2" "YU" "all" "all" "and"
[6] "be" "be" "can" "can" "character"
[11] "character" "coded" "coded" "combinations" "command"
[16] "contain" "different" "does" "following" "for"
[21] "known." "line" "list" "listed" "mean"
[26] "names" "names" "necessarily" "not" "of"
[31] "parameters." "set" "sets" "several" "that"
[36] "the" "the" "these" "used" "with"
A possible fix seems to be to replace
ext <- readLines(icfile)
by
ext <- grep("/$", readLines(icfile), value = TRUE)
but I don't know if that's guaranteed to work.
