ggragged extends the faceting system in ggplot2 to ragged grids – a
hybrid layout between facet_wrap() and
facet_grid().
facet_ragged_rows() groups panels into rows of
(potentially) varying lengths.facet_ragged_cols() groups panels into columns of
(potentially) varying lengths.Install the current release from CRAN:
install.packages("ggragged")Or the development version from GitHub:
remotes::install_github("mikmart/ggragged")Ragged grids can be used to clearly separate nested hierarchies in the panel layout:
library(ggplot2)
library(ggragged)
p <- ggplot(Indometh, aes(time, conc)) + geom_line()
# Panels for each subject, with cohorts on separate rows
p + facet_ragged_rows(
vars(Cohort = 1 + Subject %in% 3:6),
vars(Subject = as.character(Subject)),
labeller = label_both
)
# Panels for each subject, with cohorts in separate columns
p + facet_ragged_cols(
vars(Subject = as.character(Subject)),
vars(Cohort = 1 + Subject %in% 3:6),
labeller = label_both
)
