In mathosi/jj: Just Joise

arrange ggplots in a grid

Description

plot multiple plots together in a grid based on a list of ggplot objects The following error can occur and is related to problems with the legend. Try to change legend.pos to solve it: Error in grid.Call(C_convert, x, as.integer(whatfrom), as.integer(whatto), : Viewport has zero dimension(s)

Usage

jj_arrange_ggplots(
  gg_list,
  nplots = 4,
  cols = 2,
  legend.pos = NULL,
  equal_size_plots = TRUE
)

Arguments

gg_list	list of ggplot objects
nplots	number of plots to combine together
cols	number of columns for the plot layout
legend.pos	position of legends. One of 'left','right','top','bottom','none'. If null, do not change legend positions
equal_size_plots	if TRUE, make all individual plots the same size

Examples

df = data.frame(a=rnorm(100, 0, 5), b=rnorm(100, 0, 5), d=rbinom(100, 50, 0.3), e = sample(c('A','B', 'C'), 100, replace=T))
ggl = list()
ggl[[1]] = ggplot(df, aes(x = a, y = b, colour=d)) + geom_point()
ggl[[2]] = ggplot(df, aes(x = a, y = b, colour=e)) + geom_point()
ggl[[3]] = ggplot(df, aes(x = a)) + geom_histogram()
jj_arrange_ggplots(ggl, nplots = 4, cols = 2)
jj_arrange_ggplots(ggl, nplots = 4, cols = 2, legend.pos = 'none')
