Subject: ggsave() with width only
In-Reply-To: <9e4dcd06-68b7-5bf5-b4d0-85f2b549abd4@rgzm.de>
Dear Adam,
The function cowplot::save_plot() actually doesn't help in my case
because I need to know the aspect ratio (which I don't in advance). If I
knew the aspect ratio, I could calculate the height from the width or
vice-versa, and then I could use ggplot2::ggsave().
I have found a workaround using the package patchwork: I put the plots
together into one plot, that I save on an A4 page.
Best,
Ivan
