There are numerous ways of importing data from excel. One is to save as a
.csv and use the read.csv function. Or, you can copy to the clipboard and
use the read.delim("clipboard",header=T) function.

them on the x axis, and the numbers on the y?

As these are all introductory elements of using R, going through the
numerous intro R manuals available online is your best bet. Try:
and also under "Contributed Documentation" at the above site.
