R help - Jun 2014 - Publication-ready figures with two plots

Hi all,

I have quite a specific problem with producing 300ppi plots in tiff format
for publication. I have found ggsave to work beautifully with a single
plot, which can then be exported to GIMP to compress the resulting large
tiff file. However, it seems to run into trouble when plotting two figures
next to each other, e.g.

plot1<-ggplot(.........)
plot2<-ggplot(.........)
grid.arrange(plot1, plot2, ncol=2)

ggsave(filename = "Figure 1.tiff", scale = 1, width = 10, height = 5,
units
= "cm", dpi = 300)

This results in only plot2 appearing in the resulting tiff file, with plot
1 nowhere to be seen.

I will also have a figure which does not use ggplot, but consists of three
plots produced with barplot2 and matplot, but presumably this faces a
similar problem. Essentially, could anyone suggest a way of translating
what appears in the plot appearing in the plot window (I use RStudio) to a
high-resolution tiff file with as little fuss as possible?

Many thanks,

Adam

I you do not get a reply that shows how to do this natively in R, Google

   "GIMP montage"

and follow the directions, or use the 'montage' command line tool from 
imagemagick.

Dear Adam,

ggsave() works only with single ggplot object. You need the standard R way of
saving those plots.
1) open a suitable device
2) plot the figures
3) close the device

tiff(filename = "Figure 1.tiff", scale = 1, width = 10, height = 5,
units = "cm", dpi = 300)
grid.arrange(plot1, plot2, ncol=2)
dev.off()

To call in the statistician after the experiment is done may be no more than
asking him to perform a post-mortem examination: he may be able to say what the
experiment died of.

Hi all,

I have quite a specific problem with producing 300ppi plots in tiff format for

can then be exported to GIMP to compress the resulting large tiff file. However,
it seems to run into trouble when plotting two figures next to each other, e.g.
