Is there a package in R for XTFEVD procedure (Plümper & Troeger)?
Also, are there any examples of Hausman-Taylor implementation in R?
I understand that it can be done using plm package but could not find
examples with actual data

Dear list,
I'm looking for a way to count the number of "|" within an object.
The character "|" is used to separated ids.
Assume a data (d) structure like
Var
NA
NA
NA

1|2
1|22|45

I need to know the maximum number of ids within one object. In this case 3
