[R] Counting defined character within String

[Kunzler, Andreas]

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
NA
NA
1
1|2
1|22|45
3
4b|24789

I need to know the maximum number of ids within one object. In this case 3 (1|22|45)


Does anybody know a better way?

Thanks

Mit freundlichen Grüßen

Andreas Kunzler
