![]() ![]() The above solutions may not be efficient if you want to plot multiple ggplot plots using a loop (e.g. For a general overview of the different options, and some historical context, this vignette offers additional information. library(egg)īoth functions are compatible with ggsave(). It merely places grobs in a rectangular layout.įor the special case of ggplot2 objects, I wrote another function, ggarrange, with a similar interface, which attempts to align plot panels (including facetted plots) and tries to respect the aspect ratios when defined by the user. when they have axis labels of different size, but this is by design: grid.arrange makes no attempt to special-case ggplot2 objects, and treats them equally to other grobs (lattice plots, for instance). One common complaint is that plots aren't necessarily aligned e.g. More options are detailed in this vignette. In its simplest form, the code would look like: library(ggplot2) I wrote grid.arrange() to provide a simple interface as close as possible to par(mfrow). This enables greater flexibility than the draw this now model of base graphics, but the strategy is necessarily a little different. The par(mfrow.) command doesn't have a direct equivalent, as grid objects (called grobs) aren't necessarily drawn immediately, but can be stored and manipulated as regular R objects before being converted to a graphical output. Ggplot2 is based on grid graphics, which provide a different system for arranging plots on a page. There is also multipanelfigure package that is worth to mention.
