ReadSparseMatrix: Reads sparse matrixes from *.lrn files.

In aultsch/DataIO: IO Handling for Files Containing Data

Description

Zum Lesen von duenn besetzten Matrizen, die in *.lrn-Files gespeichert sind. (Gegebenenfalls mit ergaenzender *.names-Datei.)

Usage

ReadSparseMatrix(FileNameWithoutExt, InDirectory)

Arguments

FileNameWithoutExt	String, name of the file to be written. Without extention!
InDirectory	the directory where to read from; if not given: current dir.

Value

A list of:

ZeilenInd	numeric vector. index of rows that contain non-zero entries
SpaltenInd	numeric vector. index of columns that contain non-zero entries corresponding to ZeilenInd such that Matrix[ZeilenInd, SpaltenInd]==non-zero
Inhalt	numeric vector. Containing the values of the sparseMatrix at corresponding ZeilenInd and SpaltenInd.
Dimension	numeric vector. Dimensions of the complete sparseMatrix. Default: c(max(ZeilenInd),max(SpaltenInd))
Header	string vector. Header for columns (including Key).
Key	numeric vector: unique key for each line
DimNames	OPTIONAL OUTPUT: If FileNameWithoutExt.names exists: string list. Names of the complete sparseMatrix fitting Dimension. Must not be quadratic. Must not be of the same length as ZeilenInd (iff there are rows containing only zeros). First list element are rownames, second columnnames.
