One of my first posts, so I'll do my best. I've tried searching this, which is how I got this far..but I could use some help converting some time data in the form mm:ss.000 (that's milliseconds at the end) to seconds with a fraction at the end. For example, 2:15.45 should come out to 135.45.
This works:
t <- "02:15.45" (as.numeric(as.POSIXct(strptime(t, format = "%M:%OS"))) - as.numeric(as.POSIXct(strptime("0", format = "%S"))))
But this one, where I'm trying to use a column of my dataframe (originally in character form) does not work:
starttimesFPsnapjumps <- FPsnapjumps$start (as.numeric(as.POSIXct(strptime(starttimesFPsnapjumps, format = "%M:%OS"))) - as.numeric(as.POSIXct(strptime("0", format = "%S"))))
Perhaps it's because my numbers in the column have an extra 0 - they are mm:ss.000. Any thoughts? Thanks in advance.
