...v <- c(1, 1, 2, 2, 2, 3, 3, 4, 4, 4) When I do > hist(v) I get the x-axis of the histogram with floating point labels: 1.0, 1.5, 2.0, etc. Is it possible to tell R that the data consists of categories, i.e. that I only want the category names (1, 2, 3, 4) on my x-axis? Thanks in advance, Rehceb Rotkiv

...of the column. How would I do that? Rcommander, the ultimate newb-tool, has a function `colPercents' which is exactly what I need, but I do not want to load the whole thing into memory just for this function. Is there a way to load just this single function from the Rcmdr package?
