R help - Mar 2005 - Unexpected error "subset assignment" (bug?)

Hi,

I run into following problem. It seems to me that operation in the 3rd line
should be valid.
> b = matrix(as.raw(0), 8,8)
> q = as.raw(1:8)
> b[1,] = q
Error: incompatible types in subset assignment
> length(b[1,])
[1] 8
> typeof(b[1,])
[1] "raw"
> length(q)
[1] 8
> typeof(q)
[1] "raw"

Is this a bug or a "feature"?

I didn't know anything about as.raw(), so I did ?as.raw and it refer
to raw vector, so my guess is that it doesn't work with matrix types. 
The following modified code seems to work, however:

b = matrix(0, 8,8)
q = 1:8
b[1,] = q
b <- as.raw(b)
dim(b) <- c(8,8)

HTH,
Roger
