[R] Merging 2 files with different timestamp

[jim holtman]

Is this the format of a column within the two different files?  If they are
columns, here is a way of converting to a common format for merging:


> # convert to POSIXct
> date1 <- as.POSIXct("27-Dec-12 23H 30M 0S", format = "%d-%b-%y %HH %MM
%SS")
> date2 <- as.POSIXct('2012-12-27 2330', format = "%Y-%m-%d %H%M")
>
> # now convert to a common character format for merging
> date1_new <- format(date1, "%Y%m%d%H%M%S")
> date2_new <- format(date2, "%Y%m%d%H%M%S")
> date1_new
[1] "20121227233000"
> date2_new
[1] "20121227233000"

What is the problem that you are trying to solve?
Tell me what you want to do, not how you want to do it.
