R help - Jul 2015 - How to feed graphic device (png, jpeg etc) with different files names

Dear list,

I define a function to export a bunch of plots. A sample code is something
like the follow

export.plots<-function(export.type='pdf',...){

match.fun(export.type) (...)

print(plot.func1(...))
print(plot.func2(...))
print(plot.func3(...))
...
print(plot.funcn(...))

dev.off()

}

If I do pdf , everything can be exported into one file. But for other
devices, each graph is one file. Since I have so many graphs to export, I
can't tell which is what from the file names. I was thinking if I can
construct a file name for each of the 'print" function then to feed the
information to the graphic device to have an informative file name. Is it
possible? Thanks.

Use dev.off and re-open the device.
