Dear useRs, I produce several independent ggplot2 plots and I would like to save them to a fixed width (for publications), but the height (and therefore aspect ratio) is different from plot to plot. How can I save my plots with ggsave() supplying only a fixed width but without knowing the height nor the aspect ratio? If I specify the width only, the plots are truncated in width because the aspect ratio is not correct. Thank you for the tip!

I use an rmarkdown file to generate consistent output figures and tables for html or Word. I just use Rnw files directly if I am generating LaTeX. I do not use R files for building output... and I never use ggsave. So you might consider altering your approach to bypass the question entirely.

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)
