Dear colleagues:
I have a set of long names structured as follows:
ABCD~~blablablablablablablablabla
EFGHI~~boobooboobooboo
JKL~~foofoofooblablabooboo
MNOPQRST~~oopsoopsoops
,etc.
I need to abbreviate these names in order to obtain
ABCD
EFGHI
JKL
MNOPQRST
etc.
Any suggestions?
You can use regexpr and substring; for example:
> name <- "ABCD~~blablablablablablablablabla"
> substring(name, 1, regexpr("~", name) - 1)
[1] "ABCD"

I hope that this helps,
John
