Is there a way to convert mm:ss.00 to seconds.00?

Question

I\'ve got some performance time data in mm:ss.00 format (i.e. 02:15.45, or 00:34.58). R is recognizing the variable as a factor, but I\'d like to convert each performance t

Answer 1

Look into strptime. Specifically

t = "02:15.45"
(as.numeric(as.POSIXct(strptime(t, format = "%M:%OS"))) - 
    as.numeric(as.POSIXct(strptime("0", format = "%S"))))

This will work, but is possibly a little awkward (doing it this way mostly because of POSIXct's annoying automatic unit conversion...)
