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.
Are you looking at a bar graph where the lessons have the names nested below
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.
