Tools to create a layout for figures made of multiple panels, and to fill the panels with base, 'lattice', 'ggplot2' and 'ComplexHeatmap' plots, grobs, as well as content from all image formats supported by 'ImageMagick' (accessed through 'magick').
Tools to create a layout for figures made of multiple panels, and to fill the panels with base,
lattice and ggplot2 plots, grobs, and bitmap images as supported by
ImageMagick (through the
To install the package, you first need the devtools package.
Then you can install the multipanelfigure package using
Layouts are matrices of panels that contains plots, grobs or images. Create them with the
You can specify the total width and height of the figure (the default unit is millimetres):
library(multipanelfigure)figure1 <- multi_panel_figure(width = 180, height = 180,columns = 3, rows = 3)
Or you can specify widths and heights of individual columns and rows.
figure2 <- multi_panel_figure(width = c(20, 30, 40),height = c(10, 20, 30))
When no panels are filled, printing the figure (by typing its name) displays the layout. Notice that by default a 5 mm spacer is included between rows and between columns. (This can be adjusted using
Plots and images are added into the figure by filling panels using
lattice plot variables are added directly. The syntax is cleanest using magrittr pipes:
library(lattice)library(magrittr)a_lattice_plot <- xyplot(height ~ age, Loblolly)figure1 %<>% fill_panel(a_lattice_plot)
ggplot2 plots variables are also added directly. In this case, to put it in the second column from the left (top row), specify the
library(ggplot2)library(magrittr)a_ggplot <- ggplot(Loblolly, aes(age, height)) + geom_point()figure1 %<>% fill_panel(a_ggplot, column = 2)
Plots created using base graphics must be converted to grid-based plots and captured using
a_base_plot <- capture_base_plot(with(Loblolly, plot(age, height)))figure1 %<>% fill_panel(a_base_plot, column = 3)
grid grobs are also added directly. Plots and images can be made to span multiple panels by defining starting and stopping columns using
column and/or starting and stopping rows using
row. The following example adds the grob to the second and third rows from the top (first column).
library(grid)a_grob <- linesGrob(arrow = arrow())figure1 %<>% fill_panel(a_grob, row = 2:3)
Bitmap images (such as JPEG, PNG, and TIFF images) are added via a string giving their location: either a path to a location on disk, or a URL.
figure1 %<>% fill_panel("",column = 2:3,row = 2:3)
Once panels have been added to the figure, printing it displays the figure.
1.1.0 As caTools is being archived (no response of maintainer to CRAN requests), caTools-dependent gif support is temporarily dropped. 0.8.4 Added support for importing GIFs into panels. Different scaling options for image panels. 0.8.3 Bug fix release to support latest version of rsvg package. 0.8.2 First public release.
