Description

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

Usage

ancestrymap2lfmm(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 matric in the lfmm format. By default, the name of the output file is the same name as the input file with a .lfmm 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.

Examples

# Creation of a file called "example.ancestrymap"
# 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 lfmm format ("example.lfmm").
# By default,   the name of the output file is the same name
#               as the input file with a .lfmm extension.
# Create file:  "example.lfmm".
output = ancestrymap2lfmm("example.ancestrymap")

# Conversion    from the ancestrymap format (example.ancestrymap) 
#               to the geno format with the output file called plop.lfmm.
# Create file:  "plop.lfmm".
output = ancestrymap2lfmm("example.ancestrymap", "plop.lfmm")

# As force = false and the file "example.lfmm" already exists,
# nothing happens.
output = ancestrymap2lfmm("example.ancestrymap", force = FALSE)
