array dimension changes with assignment
Why does the assignment of a 3178x93 object to
another 3178x93 object remove the dimension attribute?
> GT <- array(dim = c(6,nrow(InData),ncol(InSNPs)))
> dim(GT)
[1] 6 3178 93
> SNP1 <- InSNPs[InData[,"C1"],]
> dim(SNP1)
[1] 3178 93
> SNP2 <- InSNPs[InData[,"C2"],]
> dim(SNP2)
[1] 3178 93
> dim(pmin(SNP1,SNP2))
[1] 3178 93
> GT[1,,] <- pmin(SNP1,SNP2)
> dim(GT)
