read.marrayInfo {marrayInput} | R Documentation

## Create objects of class marrayInfo

### Description

This function creates objects of class `marrayInfo`. The `marrayInfo` class is used to store information regarding the target mRNA samples co-hybridized on the arrays or the spotted probe sequences (e.g. data frame of gene names, annotations, and other identifiers).

### Usage

    read.marrayInfo(fname, info.id=NULL, labels=NULL, notes=fname, sep="\t",skip=0, quote="\"", ...)

### Arguments

`fname` | the name of the file that stores information on target samples or probe sequences. This is usually a file obtained from a database.
`info.id` | the column numbers in `fname` that contain the required information.
`labels` | the column number in `fname` which contains the names that the user would like to use to label spots or arrays (e.g. for default titles in `maPlot`.
`notes` | object of class character, vector of explanatory text
`sep` | the field separator character. Values on each line of the file are separated by this character. The default is to read a tab delimited file.
`skip` | the number of lines of the data file to skip before beginning to read data.
`quote` | the set of quoting characters. By default, this is disable by setting `quote="""'.
`...` | further arguments to `scan`.

    datadir <- system.file("data", package="marrayInput")

    ## Reading target sample information
    swirl.samples <- read.marrayInfo(file.path(datadir, "SwirlSample.txt"))

    ## Reading probe sequence information
    swirl.gnames <- read.marrayInfo(file.path(datadir, "fish.gal"),
                                    info.id=4:5, labels=5, skip=21)
