Dear all,
I have a vector, which looks about like this:
str <- c("14.XYZ", "15.ABCDE", "16.dkieowo", "120.EIDKAI")
I need to extract the numerical characters out of the string, so I receive
in the end a normal vector containing:
vec <- c(14, 15, 16, 120)
I need a generic solution for this. My actual vector contains about 403
strings, and it is bound to change with different versions of my
calculations. So I need something that either extracts all numeric
characters or deletes everything else.
I hope you can help me out.
Best,
Karl
