[R] Points but no lines in qplot.

[Sarah Goslee]

Hi,

You seem to be using qplot() from the ggplot2 package, but you really
need to specify: there are several packages with a function of that
name.

That said, when I run your example I get a plot with both lines and
points, which means we're going to need more information from you,
specifically sessionInfo(). You may just need to update R and/or the
package.

Mine, which works:
> sessionInfo()
