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

You can do this easily with the Lubridate package. If you use the format "h:m:s" you can convert the variable to a lubridate object with

hms("12:12:54")

And then convert it to seconds with

seconds(hms("12:12:54"))

Here is a link to the lubridate article in JSS
