Updating xpose4 stratification headers in VPCs

Dear all,

I realise that xpose4 is perceived as getting a bit old, but as far as I can tell it is still very widely used in the community, and auto-generated R-code from PsN still uses xpose4. My own hesitation has always been in the perceived lack of options to customise the output, but it has so many handy features šŸ˜Š. Currently I'm running VPCs with multi-level stratification implemented using the STRT variable in NONMEM code, and my resulting VPCs have 4 graphs. However, the headings of these graphs are the pretty ugly "STRT==0.5", "STRT==101" etc. Is there a way to change this to a nice factor with customisable layout? And while we're at it: is there a way to access/extract the individual graphs so these can be formatted and/or printed separately?

Thanks very much in advance!

Kind regards,

Rik
