I’m using the latest drop of plotly from github, this appears to fix the issue related to the HTTP 500 error. And while i can export a png successful via command line I get an error trying to export as pdf:
If I run
plotly_IMAGE(field.defects.df.weekly.pc.bar, width = 1000, height = 400, format = “pdf”, scale = 2,
out_file = “~/Desktop/Graph6.pdf”)
Error in process.image(append_class(resp, “image”)) : Payment Required (HTTP 402).
