Thanks to this great post http://www.imachordata.com/?p=730 we can now put multiple plots on a display with ggplot2. This provides somewhat similar functionality to ‘par(mfrow=c(x,y))’ which would allow multiple plots with the base plot function. gridExtra doesn’t have quite the same level of options as ‘par’, but the syntax is simple.

`grid.arrange( graph1, graph2, ncol=2`

Simple. ‘grid.table’ is worth checking out as well.

**NOTE: Saving**

I normally use ‘ggsave(…)’ to save my plots created with ggplot2. This (as yet) doesn’t work with using grid.arrange. A work around is to use a more tradition/base approach:

```
pdf("filename.pdf")
grid.arrange( graph1, graph2, ncol=2)
dev.off()
```

Enjoy!
