Do you mean the points (circles) shown for example in: > set.seed(123) > dat <- rt(10000, df = 3) > boxplot(dat) ?? If so, these are your *data* and shouldn't be removed. These are the points that lie further than 1.5 * the length of the box, with a caveat explained on ?boxplot.stats You could do > boxplot(dat, range = 0) But the resulting plot will require explanation to those used to see a boxplot sensu Tukey.
