two bugs ?

Dear,
I thought these two example are bugs.
example 1: colnames issue
> tmp<-data.frame(value=1:3,group1=1:3) > if (length(tmp$group)>1) z<-1 else z<-2 > print(z)
[1] 1
tmp$group is 1:3 because of partial matching in "$" (which is not a bug, but maybe a design infelicity).
example2 : length issue
tmp<-data.frame(value=1:3,group=c("a","a","b") )
tmp1<-gsummary(tmp,FUN=length,groups=tmp$group)
tmp1
value group a 2 a b 1 b
tmp<-data.frame(value=1:3,group=c("a","c","b"))
tmp1<-gsummary(tmp,FUN=length,groups=tmp$group)
tmp1
value group a 1 a b 3 b c 2 c
That's how gsummary (from nlme) works. Look at the definition of FUN.
