I have a dataframe obtained using read.csv from an excel file.  Its first 
column is times, running from 18:00 to 19:30.  If I want to plot other columns 
against time, do I need to convert those somehow, and how would I do that?

If I run plot(b$time,b$myvar) I get a decent plot, but a friend suggests that R 
is just treating those numbers as text, and putting them in alphabetical order. 
 True?
