ggalign (development version)

New features

• new fortify_matrix.GISTIC() method for GISTIC object from maftools package (#24).

• + operator now will respect with_quad().

• new ggalign_attr_set() and ggalign_attr_get() for basic operations of attached attribute.

• new geom_draw() function to draw ggplot2 layer with customized draw function.

• new geom_subrect() and geom_subtile() to subdivide rectangles with shared borders into a grid.

Bug fixes

• fix wrong results of fortify_matrix.MAF() method

Improvements

• Now, with_quad() wraps the object into a list with the class with_quad. This approach offers greater flexibility in defining the actions associated with with_quad, allowing for more customizable behavior (#26, @Yunuuuu).

Features

ggalign pacakge provides two layout to arrange ggplot objects:

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

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

To further customize these layouts, we offer following functions:

• 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("layout-customize").

Additionally, plots can be added in the layout with following functions:

• 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("layout-plot").
