facet_wrap(nrow) ignored
Dear useRs, I have an issue with the argument nrow of ggplot2::facet_wrap(). Let's consider some sample data: mydf <- data.frame(grp = rep(letters[1:6], each = 15), cat = rep(1:3, 30), var = rnorm(90)) And let's try to plot with 5 rows: library(ggplot2) ggplot(data = mydf, aes(x = cat, y = var)) + geom_point() + facet_wrap(~grp, nrow = 5) It plots 2 rows and 3 columns rather than 5 rows and 2 columns as wanted. These plots are as expected: ggplot(data = mydf, aes(x = cat, y = var)) + geom_point() + facet_wrap(~grp, nrow = 2) ggplot(data = mydf, aes(x = cat, y = var)) + geom_point() + facet_wrap(~grp, nrow = 6) My guess is that 5 rows is not ideal for 6 facets (5 facets in 1st column and only 1 facet for 2nd column) so it overrides the value of nrow. In the case of 2 or 6 rows, the facets are well distributed in the layout. The reason why I need 5 rows with 6 facets is that this facet plot is part of a patchwork and I would like to have the same number of rows for all facet plots of the patchwork (so that they all align well). Is there a way to force the number of rows in the facet_wrap()? Thank you in advance. Best, Ivan
