assign.gdsn: Assign/append data to a GDS node

Description

Assign data to a GDS node, or append data to a GDS node

Usage

assign.gdsn(node, src.node=NULL, resize=TRUE, seldim=NULL, append=FALSE, .value=NULL, .substitute=NULL)

Arguments

node

an object of class gdsn.class, a target GDS node

src.node

an object of class gdsn.class, a source GDS node

resize

whether call setdim.gdsn to reset the dimension(s)

seldim

the selection of src.obj with numeric or logical indicators, or NULL for all data

append

if TRUE, append data by calling append.gdsn; otherwise, replace the old one

.value

a vector of values to be replaced in the original data array, or NULL for nothing

.substitute

a vector of values after replacing, or NULL for nothing; length(.substitute) should be one or length(.value); if length(.substitute) = length(.value), it is a mapping from .value to .substitute

Value

None.
