This package extends ggplot2 and offers several benefits for organizing and arranging plots. It is specifically designed to align the axes of multiple ggplot objects consistently. This functionality is particularly useful for plots where data order needs to be manipulated. One common application of this package is in effectively organizing combinations of plots, such as a dendrogram and a heatmap.

You can install the development version of ggalign from GitHub with:

# install.packages("remotes")
remotes::install_github("Yunuuuu/ggalign")

This package now depends on some un-merged features of patchwork. Please see thomasp85/patchwork#373. If you want to try it, you should install patchwork with pak::pkg_install(Yunuuuu/patchwork@align_axis_title).

ggalign pacakge provides two layout to arrange ggplot objects:

• layout_heatmap()/ggheamtap(): Arrange ggplot into a Heatmap layout. See vignette("layout-heatmap") for details.

• layout_stack()/ggstack(): Arrange ggplot vertically or horizontally. See vignette("layout-stack") for details.

To further customize these layouts, the ggalign package offers several Align objects:

• align_group(): Group layout axis into panel with a group variable.
• align_kmeans(): Group layout axis into panel by kmeans
• align_reorder(): Reorders layout observations based on weights or summary statistics.
• align_dendro(): Reorder or Group layout based on hierarchical clustering

For more detailed instructions on customizing layouts, see the vignette: vignette("align-layout").

Additionally, the following Align objects can be used to add plots directly into the layout:

• align_gg()/ggalign(): Create ggplot object with a customized data.
• align_panel()/ggpanel(): Create ggplot object with the layout panel data.

For more information on adding plots, refer to the vignette: vignette("align-plot").
