Re: [R] reset par() within plot layout
OK, maybe I oversimplified the example, because you are of course correct... I am working on a function, which I feed data to plot in layouts of specified dimensions. I want to be able to set any par() variables for each plot in the layout. Because the next plot does not know which par() variables were changed in the previous plot, I want to reset all par() variables after each plot, rather than simply change back one specific par() variable. So I really need to reset par() without 'messing with' my layout. stephen sefick wrote: > Maybe something like this? > > #Desired result is a layout of 2 plots: one red and one black > par(mfrow=c(2,1)) > > par(col="red") > plot(1:100) > > par(col="black") > plot(1:10) > > On Fri, Oct 23, 2009 at 7:26 AM, Janke ten Holt wrote: >> Dear list, >> >> I would like to produce a matrix of plots, where par() is reset after >> each plot (see below [simplified] example).
