read.spot {sma}R Documentation

Reading in Data Generated by the Image Analysis Package Spot

Description

Reads in a data file in table format and creates a data frame with the same number of rows as there are lines in the file, and the same number of columns as there are fields in the file.
`read.spot': reads in the data file generated by the microarray image extraction library Spot.

Usage

read.spot(name, dir=".", sep="\t", header=TRUE, ...)

Arguments

name character string naming the data file from which to read the data.
dir character string naming the directory that contains the data file. The default setting is the current directory.
sep the field separator (single character), often "t" for tab delimited fields. If omitted, any amount of white space (blanks or tabs) can separate the fields. To read fixed format files, make sep a numeric vector giving the initial columns of the fields.
header logical flag: if TRUE, then the first line of the file is used as the variable names of the resulting data frame.
... parameters for read.table may also be supplied as arguments to the function (see read.table).

Value

as in read.table, a data frame (data.frame) containing a representation of the data in the file.
