Subject: Re: [R] Save multiple plots in a single pdf file when the plots are generated by a single plot command It looks like you have one too many pdf objects open. I can page-up and page-down to look at the different plots. Note: we have used parameters cex to decrease the size of labels and mai to define margins. In cowplot: Streamlined Plot Theme and Plot Annotations for 'ggplot2'. The only difference between the two is that, mfrow fills in the subplot region row wise while mfcol fills it column wise.

If you are working with RStudio, the plot can be exported from menu in plot panel (lower right-pannel). With the par( ) function, you can include the option mfrow=c(nrows, ncols) to create a matrix of nrows x ncols plots that are filled in by row.
