Converts DICOM Header Field to a Matrix

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.
