Insofar as I understand the plotting code, this should not happen -
and in fact quite a bit of work went into making sure that things plot
okay even if the function is not defined right at or near (say) your
lower bound. However, the plot boundaries are different from the show
xmin and xmax options, so maybe that is the confusion? But I don't
think what you are describing should happen; all randomization is
within the bounds prescribed e.g. plot(1/x,0,1) would randomize
between 0 and 1 but not plot outside that range, for the very good
reason you mention.
