create_demo_map_table: Create a demo genetic mapping '.map' table

In richelbilderbeek/plinkr: Interface to PLINK

Create a demo genetic mapping .map table

Description

Create a demo genetic mapping .map table. It is simply a map of SNPs that are located on different chromosomes.

Usage

create_demo_map_table(traits = create_demo_traits())

Arguments

traits

one or more traits with a clear genetic architecture and a known minor allele frequency, as, for example, created by create_demo_traits.

Details

Each SNP is positioned on a different chromosome. As PLINK allows for a maximum of 95 chromosomes, the 96th SNP is placed on the first chromosome again, after which the chromosomes are travered again.

Examples

# Default demonstration genetic mapping table
create_demo_map_table()

# Random, 1 SNP
create_demo_map_table(traits = create_random_trait())

# Random, 2 SNPs
create_demo_map_table(traits = create_random_trait(n_snps = 2))
