I am regulary using 'boxplot ' function or its analogue - 'bwplot ' from
the 'lattice ' library. But they are as far as I understand totally
flawed in functionality hello
is R able to suppress tick labels (not tick marks)? i know there is a way
around this with axes F and then draw new axes but it would be easier to
suppress them in the first place.
