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?

See

        ?max
        ?count.fields

and, if you are noit using this on a text file,

        ?textConnection

count.fields(textConnection("
+ Var
+ NA
+ NA
+ NA
+ NA
+ NA
+ 1
+ 1|2
+ 1|22|45
+ 3
+ 4b|24789
+ "),sep="|")
 [1] 1 1 1 1 1 1 1 2 3 1 2

HTH,

Chuck


Thanks
