Why not use the interactive histogram in iplots? ihist(x) Then you
can vary the binwidth interactively and get a very quick idea of the
structure of your data by looking at a range of plots with different
binwidths. Relying on a single plot to reveal everything about a
variable's

You may want to look at the nws package (there are others that also help with
parallel versions, but on windows, nws seems to work the best (at least in my
experiance so far)).

There is a very basic interface between R and gnuplot in the TeachingDemos
package. Look at the help for gp.plot.
gp.open will run gnuplot and link it to R, gp.plot will send data to gnuplot
and create a scatterplot. (gp.send will send extra commands to gnuplot and
gp.close will clean up).
It would be helpful if you provided commented, minimal,
self-contained, reproducible code.
What does str(all_differ) say? That will tell you the structure of
the object that you are trying to work with.
