removing part of a string
I would use
sub("\\(.*\\)", "()", s)
It is essentially the same as Rui's suggestion, but I find the purpose to
be more clear. It might also be a little more efficient.

Hello,
Try this.
ss1 <- "z:f(5, a=3, b=4, c='1:4', d=2)"
ss2 <- "f(5, a=3, b=4, c=\"1:4\", d=2)*z"
fun <- function(s) sub("(\\().*(\\))", "\\1\\2", s)
fun(ss1)
#[1] "z:f()"
fun(ss2)
#[1] "f()*z"
Hope this helps,

dear all, I am stuck on the following problem. Give a string like ss1<- "z:f(5, a=3, b=4, c='1:4', d=2)" or ss2<- "f(5, a=3, b=4, c=\"1:4\", d=2)*z" I would like to remove all entries within parentheses.. Namely, I aim to obtain respectively "z:f()" or "f()*z" I played with sub() and gsub() but without success.. Thank you very much for your time, best, vito
