ancestrymap2geno: Convert from 'ancestrymap' to 'geno' format

In LEA: LEA: an R package for Landscape and Ecological Association Studies

Description

A function that converts from the ancestrymap format to the geno format.

Usage

ancestrymap2geno(input.file, output.file = NULL, force = TRUE)

Arguments

input.file	A character string containing a path to the input file, a genotypic matrix in the ancestrymap format.
output.file	A character string containing a path to the output file, a genotypic matrix in the geno format. By default, the name of the output file is the same name as the input file with a .geno extension.
force	A boolean option. If FALSE, the input file is converted only if the output file does not exist. If TRUE, convert the file anyway.

Value

output.file

A character string containing a path to the output file, a genotypic matrix in the geno format.

Examples

# Creation of of file called "example.ancestrymap"
# a file containing 4 SNPs for 3 individuals.
data("example_ancestrymap")
write.table(example_ancestrymap,"example.ancestrymap",
col.names = FALSE, row.names = FALSE, quote = FALSE)

# Conversion    from the ancestrymap format ("example.ancestrymap") 
#               to the geno format ("example.geno"). 
# By default,   the name of the output file is the same name
#               as the input file with a .geno extension.
# Create file:  "example.geno".
output = ancestrymap2geno("example.ancestrymap")

# Conversion    from the ancestrymap format (example.ancestrymap) 
#               to the geno format with the output file called plop.geno.
# Create file:  "plop.geno".
output = ancestrymap2geno("example.ancestrymap", "plop.geno")

# As force = false and the file "example.geno" already exists,
# nothing happens.
output = ancestrymap2geno("example.ancestrymap", force = FALSE)
