I am using ggvis with RStudio. For instance:
library(ggvis)
mtcars %>% ggvis(~mpg, ~wt) %>% layer_points()
Then what happens is that a (static) diagram is displayed in the Viewer RStudio panel. In this panel, I can click the Export button to save the chart as .png, but is there a way to do this on the command line? (so not by hand)
I know that ggvis has a function export_png, but it only works with node.js, and I have problems with it (I am on Windows, and I can’t even run the node.js installer on my computer, but this is a separate issue that I will discuss separately).
So my question is: is there a way to capture in a .png file with an R script, which is displayed in the Viewer panel?
Or: is there a way other than export_pngsaving the ggvis diagram as a .png file?
Thanks in advance.
