Crash of xpose.data when TIME column missing

[rikardn]

I run a simple model (pheno) with the following (admittedly minimal) table:

$TABLE ID NOAPPEND NOPRINT ONEHEADER FILE=sdtab1

When trying to read the results into an xpdb with xpose.data it crashes with the following trace:

Error in (function (cl, name, valueClass) : assignment of an object of class “numeric” is not valid for @‘Data’ in an object of class “xpose.data”; is(value, "data.frame_or_NULL") is not TRUE
4.stop(gettextf("assignment of an object of class %s is not valid for @%s in an object of class %s; is(value, \"%s\") is not TRUE", dQuote(valueClass), sQuote(name), dQuote(cl), slotClass), domain = NA)
3.(function (cl, name, valueClass) { ClassDef <- getClass(cl) slotClass <- ClassDef@slots[[name]] ...
2.`Data<-`(`*tmp*`, value = tmp)
1.xpose4::xpose.data(xpose.runno, directory = results.directory, tab.suffix = tab.suffix, mod.prefix = mod.prefix, mod.suffix = mod.suffix)

Adding the column TIME to the sdtab1 stops xpose from crashing.

By default xpose4 expects the 'standard' parameters to be found in NONMEM table output. This includes IWRE, IPRE, TIME, and the NONMEM default items (DV, PRED, RES and WRES) that are added when NOAPPEND is not present in the $TABLE record. If you remove NOAPPEND then your example should work.

Ok, but in other cases xpose give helpful error messages to what is missing. For example when trying to create a basic gof plot I get:

 -----------Variable(s) not defined!-------------
 iwres is/are not defined in the current database
 and must be defined for this command to work!
 ------------------------------------------------

It would be helpful if xpose could do the same here.

Yes ... true ... will add a better error message ... thanks
