write.snp.matrix

Write a SnpMatrix object as a text file

Description

This function is closely modelled on write.table. It writes an object of class SnpMatrix as a text file with one line for each row of the matrix. Genotpyes are written in numerical form, i.e. as 0, 1 or 2 (where 1 denotes heterozygous) or, optionally, as a pair of alleles (each coded 1 or 2).

Usage

write.SnpMatrix(x, file, as.alleles= FALSE, append = FALSE, quote = TRUE, sep = " ", eol = "\n", na = "NA", row.names = TRUE, col.names = TRUE)

Arguments

`x`	The object to be written
`file`	The name of the output file
`as.alleles`	If `TRUE`, write each genotype as two alleles
`append`	If `TRUE`, the output is appended to the designated file. Otherwise a new file is opened
`quote`	If `TRUE`, row and column names will be enclosed in quotes
`sep`	The string separating entries within a line
`eol`	The string terminating each line
`na`	The string written for missing genotypes
`row.names`	If `TRUE`, each row will commence with the row name
`col.names`	If `TRUE`, the first line will contain all the column names

Value

A numeric vector giving the dimensions of the matrix written
