R help - Sep 2021 - ggsave() with width only

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)

Thank you Adam!

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

Best,
Ivan
