R help - Nov 2022 - Rare behaviour for nlme::reStruct example and question about ?lmeObject

Dear developers,

When I run the example code in the help of reStruct, I get

> library(nlme)
> rs1 <- reStruct(list(Dog = ~day, Side = ~1), data = Pixel)
> rs1
Uninitialized random effects structure
> str(rs1)
List of 2
 $ Side:Error in pdMatrix.pdSymm(x) :
  cannot extract matrix from an uninitialized object


Is it expected?

In addition to that I would like to ask if shouldn't be `terms` documented
in `?lmeObject`.


Kind regards,

Iago

1. Not developers, helpers (though there may be some developers among us,
too). Ergo, we don't make changes to code or man pages either.

2. If no satisfactory reply here, R-Sig-mixed-models is where you should
post. And post there first for mixed models questions in future.

Cheers,
Bert
