[Feedback wanted] Documentation update !!
bguiastr opened this issue ยท 2 comments
Hi everyone,
I realize that some work needs to be done on the xpose documentation and I would like your opinion on what aspects of the package YOU find confusing and/or poorly documented.
I believe that the vpc()
, vpc_data()
are among the most confusing ones but please send me your feedback and I will try to make things better!
Don't be shy ๐ !
a topic that comes around often is how to handle vpc with multiple lloq ( several studies where lloq is study specific) this is a good candidate of the workflow approach where you filter your data run the vpc with the nbins and loq specif to the study then at the end stitch everything together.
also a good liston what is missing from the old xpose.
also example of theming for those not very familiar with ggplot versus lattice.

I think an example of stratifying by endpoints would be nice.
