Re: R code blocks in org version 9.5

[Naresh Gurbuxani <naresh_gurbuxani@hotmail.com>]

It seems that org 9.5 has simplified header arguments for R code blocks that use grid graphics.

Org 9.4 requires
:results output graphics file

Org 9.5 requires
:results output file

Do other users find the same change?
