[R] Zoo - bug ???

[clangkamp]

Dear Joshua
thank you for the pointer to the width element. Actually still with
na.pad=TRUE it doesn't seem to work but attaching an extra row of NAs did. 

A1a<-zoo(c( NA, NA, 1,2,3,4,5,6, NA, NA))
A1b<-rollapply(A1a,4,mean, na.rm=TRUE, na.pad=FALSE, align="right")
A1c<-rollapply(A1a,4,mean, na.rm=TRUE, na.pad=TRUE, align="right")
cbind(A1a,A1b, A1c) 
   A1a A1b A1c
1   NA  NA  NA
2   NA  NA  NA
3    1  NA  NA
4    2 1.5 1.5

vs. the same outcome with another NA
> cbind(A1a,A1b, A1c)
   A1a A1b A1c
1   NA  NA  NA
2   NA  NA  NA
3   NA  NA  NA
4    1 1.0 1.0
5    2 1.5 1.5

But for now the issue is solved with the workaround.
