Dear Hong, 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 simpler way.

I am dealing with several sets of data that are too large to | be loaded in the same R process, but I want to plot their histogram side | by side for comparison. I am also considering how to use the 'wireframe' | function to plot these histograms in the same figure. Any suggestions | will be greatly appreciated. | | Thanks, | | Hong ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
