R Package FILEST


The R package FILEST (Fine-Level Structure Simulator) is a population genetic simulator. The simulator is able to generate synthetic datasets for single-nucleotide polymorphisms (SNP) for multiple populations. The genetic distances among populations can be set according to the Fixation Index (Fst). This tool is able to simulate outlying individuals and missing SNPs can be specified. For Genome-wide association study (GWAS), disease status can be set in desired level according risk ratio.

The R package FILEST requires KRIS and rARPACK

Here is the list of functions in the R package FILEST:

Error of Roxygen2 in building RD files

The source codes in this package include the Roxgen’s syntax. If there is a problem for generating the RD files (facing some errors) using RStudio (Build > Document), try to use roxygen2::roxygenise() instead of Build > Document from the menu. Alternatively, install the package devtools, then enable RStudio to use the functions from devtools (check Build > Configure Build Tools… > use devtools package functions if available) or run devtools::document() in the console.
