Hello all,
I want to know how often one character occurs in a given string
and the distance from between every two occurences. (distance = other
characters between them).
You should provide "commented, minimal, self-contained, reproducible code"
as asked.
And especially for a question like this one with many simple answers that
RespondeRs will shower you with if only you give them a starting point.
Use tapply, strsplit, seq, nchar, unlist, diff, "-", and table for one
way.
Chuck
thanks
