Description

Converts a vector of DICOM header information, assuming there are multiple entries per element of the vector, into a matrix.

Usage

header2matrix(hdr, ncol, sep = " ", byrow = TRUE)

Arguments

`hdr`	is the result from extracting information from a DICOM header field; e.g., using `extractHeader`.
`ncol`	is the number of columns.
`sep`	is the character string required to split entries in the header field.
`byrow`	is a logical variable (default = `TRUE`) telling the routine to populate the matrix by rows then columns.
