Choose the right picture size for a ggplot without leaving your IDE.

1. Set picture dimensions with the canvas() element.

2. Save the plot with save_ggplot().

p <- 
  ggplot(mtcars, aes(wt, mpg)) +
  geom_point() +
  ggtitle("My Plot") +
  canvas(800, 1000, units = "px")

save_ggplot(p, "my_plot.png")

install.packages("ggview")

# development version
remotes::install_github("idmn/ggview")

The package relies on the rstudioapi::viewer() function to display plot previews. By default it does not work in VS Code, but installing the R extension fixes it. It tricks the rstudioapi package into believing it is running in RStudio, and everything works.
