And another question:
I tried to group some numeric data to calculate its median but I get the following message and a missing value as result:
WARN GroupBy Skipped group(s) per column by group value(s): Intensity_IntegratedIntensity_MaskMc3="1"
I cannot see why it should not be possible to calculate a median and I don't understand this warning. In R it's no problem at all to calculate the median of this data (does not even contain missing values).
I can provide the data and workflow if needed. But maybe you already know why this happens?
