[BioC] breastCancerNKI patients question

[Xavier Robin]

Hello everyone!


According to the documentation of package breastCancerNKI, nki is a
merge of two datastets by van’t Veer et al. and van de Vijver et al. We
should have 117 patients for the former, and 295 for the latter, summing
up to 412 patients.

However the nki dataset contains only 337 patients:

> dim(pData(nki))
[1] 337  21
> dim(exprs(nki))
[1] 24481   337

Apparently the "series" annotation specifies which dataset the patients
belong to:

> table(pData(nki)$series)

 NKI NKI2
 117  220

So we would have all 117 patients from van’t Veer et al, but only 220 of
the 295 patients of van de Vijver et al.

Is it correct?
* If yes, where are the 75 remaining patients?
* If no, what did I misunderstand?


Thanks,
Xavier
