Hello all,
I would like to get a substring (first few characters till ~) from a string
I can think of way of doing so by
> string<-'yab~a+b+c'
> x<-substring(string,1,3)
> x
[1] "yab"
But if I do not know the length of the first word before ~ sign, how can I get
it out from the whole string?
Thanks,
Rebecca
