Why do you want to save the histogram on the disk? Is it not enough
just to draw them one-by-one and read in only the data necessary for
the current one?
However, you may consider:
1) look what the hist() returns. In particular, it has $counts
component which you may use in order to draw a pre-calculated
histogram later (using barplot()). Now save the returned list
either in a list or to the disk (using save()). Later plot all the
histograms. In fact, here you are not limited with different
histograms on different panels, you may e.g. put color-coded bars
from different histograms on the same plot, fit a surface
etc. This is the flexible way.
2) Divide the graphic screen (e.g. using par(mfrow)), read the
datasets one-by-one and plot corresponding histograms. This is a

| Hello all,
| Is there any way to save histogram results to a file and then read it
| back later? I am dealing with several sets of data that are too large to
