Given that you start with a character vector, this is relatively easy :

minPerGame <- c("4:30","2:20","34:10")

sapply(strsplit(minPerGame,":"),
  function(x) {
    x <- as.numeric(x)
    x[1]+x[2]/60
    }
)

gives

[1]  4.500000  2.333333 34.166667

Make sure you checked that you used read.csv() with the option as.is=TRUE. Otherwise you'll have to convert using as.character().
