after some further investigation I've found out that on my system the
bug is triggered by a call to the `convertColor` function in
`grDevices`. The following three lines of code, taken from the
`convertColor` documentation are sufficient to trigger the bug:
## --------------------
ab <- expand.grid(a = (-10:15)*10,
b = (-15:10)*10)
Lab <- cbind(L = 20, ab)
srgb <- convertColor(Lab, from = "Lab", to = "sRGB", clip = NA)
## ---------------------
It would help if someone running Ubuntu 20.04 could reproduce.
to be precise I'm running Kubuntu 20.04 rather than Ubuntu, but I don't
think that should make a difference.
Best,
Sam
