Plot Composition At the heart of patchwork lies a range of powerful functions for combining plots into an assembly of plots that can be layed out in a grid. Patchwork provides both an extension of ggplot2’s `+` based API, along with a functinal interface.
`-`(<ggplot>) `/`(<ggplot>) `\|`(<ggplot>) `*`(<gg>) `&`(<gg>)	Plot arithmetic
`wrap_plots()`	Wrap plots into a patchwork
`inset_element()`	Create an inset to be added on top of the previous plot
Layout Specifications While patchwork will automatically lay out the plots in a grid, additional control is often needed, along with the possibility of adding annotations etc.
`plot_layout()`	Define the grid to compose plots in
`plot_annotation()`	Annotate the final patchwork
`plot_spacer()`	Add a completely blank area
`free()`	Free a plot from various alignments
`guide_area()`	Add an area to hold collected guides
`area()`	Specify a plotting area in a layout
Alternative plot objects patchwork is build to work with ggplot2 but standard grobs can also be included. Further, it is possible to define empty areas if needed.
`wrap_elements()`	Wrap arbitrary graphics in a patchwork-compliant patch
`wrap_table()`	Wrap a table in a patchwork compliant patch
`wrap_ggplot_grob()`	Make a gtable created from a ggplot object patchwork compliant
Align across pages Sometimes it is necessary to align plots across pages, not within a composition, e.g. when creating figures for presentations. While not the main focus of patchwork, it still contains the necessary infrastructure to achieve this.
`get_dim()` `set_dim()` `get_max_dim()` `align_patches()`	Align plots across multiple pages
