Extracts dimension from array

1	extractA(A, a, ...)

`A`	a named array
`a`	a list of dimensions of A ( a subvector of 1:length(dim(A)) or a subvector of dimnames(A))
`...`	a vector the same length of a of integers. necessarily ...[i]<=dim(A)[a[i]]

A=array(1:(prod(2:4)),2:4);
dimnames(A)<-sapply(dim(A),seq_len)
names(dimnames(A))<-paste0("x",2:4)
extractA(A,integer(0),integer(0));
extractA(A,"x3",2);
extractA(A,c("x4","x3"),1,2);
