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,

Thanks
Mit freundlichen Grüßen
