pairlist objects
Hi,
?pairlist gives no explanation about what exactly is the difference
between a pairlist and a list (except that a pairlist of length 0
is 'NULL'). So, what's a pairlist?
class(.Options)
[1] "pairlist"
Some strange things about the "pairlist" type:
> showClass("pairlist")
Error in getClass(Class) : "pairlist" is not a defined class
