R command line and pipe using in Linux?

| Hi,
| I have a very large data file(GB) from which I only want to extract one
| column to draw histogram. This would be done several times, so I would like
| to ask if there is anyway to plot this using R from the linux command line,
| something look like this
| 
| cut -f1 xxx.txt |RplotHist ....

Have a look at littler which was written with these uses in mind:

It includes a few examples which should get you going. Also, in
non-interactive mode, your plot device will have to a file.

Hope this helps, Dirk
