Extract last two numeric parts from character vector
extractLast2numericParts extracts last 2 (integer) numeric parts between punctuations out of character vector 'x'.
Runs faster than gregexpr .
Note: won't work correctly with decimals or exponential signs !! (such characters will be considered as punctuation, ie as separator)
extractLast2numericParts(x, silent = FALSE, callFrom = NULL)
x |
main character input |
silent |
(logical) suppres messages |
callFrom |
(character) allow easier tracking of message(s) produced |
(numeric) matrix with 2 columns (eg from initial concatenated coordinates)
gregexpr from grep
extractLast2numericParts(c("M01.1-4","M001/2.5","M_0001_03-16","zyx","012","a1.b2.3-7,2"))Please choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
