Hi,

 

What is the easiest way yo convert a column of time eg 09:25:45 into
three columns of hour, minute,seconds

 

Thanks

Probably strptime() -- see its help page.

strsplit() is fairly easy but you would need to reorganize it's output.

Is that a character string: I am assuming so, but they are printed with 	
quotes?

Your subject says `date and time', but your example is only a time.

strsplit("09:25:45",":")
[[1]]
[1] "09" "25" "45"
