R-helpers,
I have a vector of character strings in which I would like to replace each
parenthetical phrase with a single space, " ". For example if I start with
x, I would like to end up with y.
x <- c("My toast=bog(keep=3 no=4) and eggs(er34)omit=32",
"dogs have ears",
"cats have tails (and ears, too!)")
y <- c("My toast=bog and eggs omit=32",
"dogs have ears",
"cats have tails ")
I'm guessing that this can be done with gsub(), but I have never mastered
the mysteries of regular expressions.
I would greatly appreciate any pointers.
Thanks.
Jean
P.S. I'm using R version 2.15.2 on Windows 7.
