Hi all
I have got something like that (actually those are column names)
[51] "X19.2.300b...80" "X19.2.400v...80" "X19.2.400b...80"
"X19.2.300v...90" "X19.2.300b...90"
[56] "X19.2.400v...90" "X19.2..400b..90" "X19.2.300v...100"
"X19.2.300b...100" "X19.2.400v...100"
in character vector. I would like to get last n figures from this
character vector but my regexpr unerstanding is inferior and I did not
succeed.
Please, is there anybody who can extract those n digits from end of each
character string? If there were only 2 digits I could use substr but there
can be one, two or three digits.
I tried several variations of
gsub("0:9$", "\\1" ,names(foto)[10])
but either got whole string or an error.
Best regards
Petr
