Extract from ?points where the pch image should be.
In R version 3.2.2, a nice image of plotting symbols is shown in the help text for points(), under chapter "'pch' values". In R version 3.2.3 this image is missing.
Environment: R Studio 0.99.878
The location where the image should be visible is shown in the attachment as the blue box with the question mark.
This was already fixed a few days ago. The image files were accidentally damaged during a bulk change to the copyright banner in the source for all the help files.
