[R] two bugs ?

[ken_lee]

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

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
