obviously did not work.
b. How would I plot the frequencies of standard for each year in xyplot?

the plot is wrong, probably because the dataframe has unnecessary repeats of
values.
I also tried converting all2 into a ftable (also tried a matrix) and naming
the columns and rows and evoking them in the xyplot. But thi...
