I would like to store and manipulate large sets of marker genotypes
compactly using "raw" data arrays. This works fine for vectors or
matrices, but I run into the error shown in the example below as soon
as I try to use 3 dimensional arrays (eg. animal x marker x allele).
> a <- array(as.raw(1:6),c(2,3))
> a
[,1] [,2] [,3]
[1,] 01 03 05
[2,] 02 04 06
> a[1,] <- raw(3)
> a
[,1] [,2] [,3]
[1,] 00 00 00
[2,] 02 04 06
> b <- array(as.raw(1:6),c(1,2,3))
> b[1,,]
[,1] [,2] [,3]
[1,] 01 03 05
[2,] 02 04 06
> b[1,1,] <- raw(3)
Error: incompatible types (from raw to raw) in array subset assignment
I can work around this with computed indices, but I wonder if this is
expected behaviour.
