pmx_plot_individual error: object 'isobserv' not found

[tmss1]

Describe the bug
pmx_plot_individual fails with the error: Error in FUN(X[[i]], ...) : object 'isobserv' not found

Screenshots

Additional context
The issue only happens with this specific project dataset but I cannot understand why.
The issue is specific to pmx_plot_individual, other plots seem to work fine.
The same model using a previous version of this dataset containing less data with only the PK endpoint worked fine.
The new dataset, containing more endpoints, was filtered to include only the PK endpoint (as in the previous dataset) but with some additional data points.
The issue persists whether the dataset was filtered inside or outside Monolix.

Is there any way to add a minimally reproducible example here?

Hi @tmss1

I am unclear why this is happening, but by reading the code isobserv is a calculated variable. I have added a fallback of isobserv to TRUE in the dataset.

While it would be better to get a small reproducible example, perhaps this default value would work in your situation.

You can try by:

remotes::install_github("ggPMXdevelopment/ggPMX", ref="235-pmx_plot_individual-error-object-isobserv-not-found")

Depending on your environment you may have to create a local library and then use:

new_lib <- tempfile()
dir.create(new_lib)
with_libpaths(new_lib, {
remotes::install_github("ggPMXdevelopment/ggPMX", ref="235-pmx_plot_individual-error-object-isobserv-not-found")
library(ggPMX)
}, action="prepend")

Then you can see if it works for this project

Fixed in e8a540f but don't have a test ☹️
