Dear Greg,

Coordinate plots typically have a horizontal (x) and vertical (y) axis. The command

        ggplot(myDat, aes(x=datetime, y = datetime)) + geom_point()

works, but I doubt that it produces what you want.

You have only one variable in your data set -- datetime -- so it's not obvious what you want to do. If you can't clearly describe the structure of the plot you intend to draw, it's doubtful that I or anyone else can help you.

Best,
 John

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

There is no variable named Y_Var in your data set. I suspect that it's intended 
to be a generic specification in the recipe you were apparently given. In fact, 
there appears to be only one variable in myDat and that's datetime. What is it 
that you're trying to do?
