[R] Set axis limits in mixtools plot

[Mike Harwood]

Hello,

Can the x and y axis limits be specified in a density plot with the
mixtools package for a finite mixture model?  Uncommenting the xlim2/
ylim2 lines in the plot command below generates 'not a graphical
parameter' warnings (and does not change the axis settings), and
uncommenting the xlim/ylim lines generates a 'formal argument "ylim"
matched by multiple actual arguments' error.  I want to use a
consistent set of axis setting for four different sets of data.
Thanks!
