setdim.gdsn: Set the dimension of data field

In zhengxwen/gdsfmt: R Interface to CoreArray Genomic Data Structure (GDS) Files

Set the dimension of data field

Description

Assign new dimensions to the data field of a GDS node.

Usage

setdim.gdsn(node, valdim, permute=FALSE)

Arguments

node	an object of class gdsn.class, a GDS node
valdim	the new dimension(s) for the array to be created, which is a vector of length one or more giving the maximal indices in each dimension. The values in data are taken to be those in the array with the leftmost subscript moving fastest. The last entry could be ZERO. If the total number of elements is zero, gdsfmt does not allocate storage space. NA is treated as 0.
permute	if TRUE, the elements are rearranged to preserve their relative positions in each dimension of the array

Value

Returns node.
