as.numeric with comma decimal separators?

Question

I have a large vector of strings of the form:

Input = c(\"1,223\", \"12,232\", \"23,0\")

etc. That\'s to say, decimals separated by commas,

Answer 1

Building on @adibender solution:

input = '23,67'
as.numeric(gsub(
                # ONLY for strings containing numerics, comma, numerics
                "^([0-9]+),([0-9]+)$", 
                # Substitute by the first part, dot, second part
                "\\1.\\2", 
                input
                ))

I guess that is a safer match...
