[R] How to plot dates

[Gregory Coats]

I need a plot that shows the date and time that each event started.
This ggplot command was publicly given to me via this R Help Mailing LIst.
But the result of issuing the ggplot command is an Error in FUN message.
ggplot(myDat, aes(x=datetime, y = Y_Var)) + geom_point()
Error in FUN(X[[i]], ...) : object 'Y_Var' not found
