Dear Ivan,
I think you don't need to provide the aspect ratio, as this should work
as well:
save_plot("/tmp/plot.png", p, base_width = 5, base_height = NULL)

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

Thank you Adam!
I'm a bit surprised that an extra package is needed for this, but why
not!
Best,

Hi,
Instead of ggsave(), use save_plot() from the "cowplot" package:
library(ggplot2)
library(cowplot)
x <- 1:10
y <- x^2
df <- data.frame(x, y)
p <- ggplot(df, aes(x, y)) + geom_point()
save_plot("/tmp/plot.png", p, base_aspect_ratio = 1, base_width = 5,
base_height = NULL)
