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,
Rui Barradas

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
