R: Read Matrix Data

read.matrix {tseries} | R Documentation

## Read Matrix Data

### Description

Reads a matrix data file.

### Usage

    read.matrix(file, header = FALSE, sep = "", skip = 0)

### Arguments

`file` | the name of the file which the data are to be read from.
`header` | a logical value indicating whether the file contains the names of the columns as its first line.
`sep` | the field separator character. Values on each line of the file are separated by this character.
`skip` | the number of lines of the data file to skip before beginning to read data.

### Details

Usually each row of the file represents an observation and each column contains a variable. The first row possibly contains the names of the variables (columns).

`read.matrix` might be more efficient than `read.table` for very large data sets.
