The problem is that the label on the graph doesn't get rendered with a

as the label you have put on the axis.

In addition to seeing the code by typing the name of the function
(and copying it from there into a file), you can also enter
"debug(fitdistr)", for example. Then the next time you use "fitdistr",
either directly or indirectly, it puts you in the environment of that
function, and you can

You mentioned lattice so I presumed that you tried a barchart in lattice
