I have the following:

s <- "abc, xyz, poi (cv, r2, 44, rghj), wer"

How can I split it so the end result is:

c("abc", "xyz", "poi (cv, r2, 44, rghj)", "wer")

Basically, strsplit the string at every comma, but outside the parentheses.

    See a similar post [here](http://stackoverflow.com/questions/37811450/spliting-the-character-into-parts); modifying nicola's post a bit: `sapply(eval(parse(text = paste("alist(", s, ")", sep = ""))), deparse)` – alexis_laz Jun 19 '16 at 16:59

Try

strsplit(s, "\\([^)]+\\)(*SKIP)(*FAIL)|, ", perl = TRUE)[[1]]
#[1] "abc"                    "xyz" 
#[3] "poi (cv, r2, 44, rghj)" "wer"
