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

scan(text=Input, dec=",")
## [1]  1.223 12.232 23.000

But it depends on how long your vector is. I used rep(Input, 1e6) to make a long vector and my machine just hangs. 1e4 is fine, though. @adibender's solution is much faster. If we run on 1e4, a lot faster:

Unit: milliseconds
         expr        min         lq     median         uq        max neval
  adibender()   6.777888   6.998243   7.119136   7.198374   8.149826   100
 sebastianc() 504.987879 507.464611 508.757161 510.732661 517.422254   100
