Upper limit of quantification plots with Xpose.vpc.both

[SimonKoele]

Dear all,

Recently I was making a model of data that had LLOQ and ULOQ data present.
Using the Xpose.vpc.both function I generated VPC plots, however the categorical subplot shows no data when plotting ULOQ data (see example below).

The function works fine when using LLOQ data.
I investigated the code of the function and found that the following part of the code still selects the LLOQ output table when ULOQ is present/selected:

for (LEVS in 1:n.levs) {
ret.new[(1 + (LEVS - 1) * n.idv.levs):(n.idv.levs *
LEVS), 1:5] <- tmp.table.2[, c(idv.index, real.index[[LEVS]],
lower.index[[LEVS]], median.index[[LEVS]], upper.index[[LEVS]])]
ret.new[(1 + (LEVS - 1) * n.idv.levs):(n.idv.levs *
LEVS), "by.var"] <- level.names[LEVS]
}

Therefore it presents the user with an empty table. For now I have created a new function that selects the right table columns to subset from to generate the plots, which does work.
I'm using xpose4_4.7.0 in R version 3.6.2.
Does anyone else have this problem?

Kind regards,

Hi Simon, Thanks for the report. I’ll make the change and push it out later in a few days.

Dear Andrew,

I am having the same issue as Simon with trying to generate a VPC using xpose.vpc.both with ULOQ data. It gives the same empty ULOQ panel shown above.

Did you ever tend to this matter?
