Hello Rainer, You need to catch the cases where the call to plot generates an error. Using your example:
## Set layout to three rows and only one column par( mfcol=c(3,1), oma=c(0,0,0,0), mar=c(4, 4, 2, 2) ) ## First row par(mfg=c(1,1)) er<-try( plot(runif(ff)), silent=T ) ## plot fails due to something. if (inherits(er, "try-error")) frame() else plot(runif(100)) ## Second row par(mfg=c(2,1)) try( plot(runif(100)) ) ##actually is plotted in first row ## Third row par(mfg=c(3,1)) plot(runif(1000)) ## plotted in third row See ?try ?inherits and ?frame Notice that you will have to change plot(runif(ff)) to whatever plot you are calling. I hope this helps, Francisco Rainer M. Krug wrote: > Greg Snow wrote: >> Oops, I read further down in your original post and see that you already >> knew about par(mfg=c(2,1)).
