LDmatrix: Generates a data frame of pairwise linkage disequilibrium...

In LDlinkR: Calculating Linkage Disequilibrium (LD) in Human Population Groups of Interest

Generates a data frame of pairwise linkage disequilibrium statistics.

Description

Generates a data frame of pairwise linkage disequilibrium statistics.

Usage

LDmatrix(
  snps,
  pop = "CEU",
  r2d = "r2",
  token = NULL,
  file = FALSE,
  genome_build = "grch37",
  api_root = "https://ldlink.nih.gov/LDlinkRest"
)

Arguments

snps	list of between 2 - 2500 variants, using an rsID or chromosome coordinate (e.g. "chr7:24966446")
pop	a 1000 Genomes Project population, (e.g. YRI or CEU), multiple allowed, default = "CEU"
r2d	r2d, either "r2" for LD R2 or "d" for LD D', default = "r2"
token	LDlink provided user token, default = NULL, register for token at https://ldlink.nih.gov/?tab=apiaccess
file	Optional character string naming a path and file for saving results. If file = FALSE, no file will be generated, default = FALSE.
genome_build	Choose between one of the three options...'grch37' for genome build GRCh37 (hg19), 'grch38' for GRCh38 (hg38), or 'grch38_high_coverage' for GRCh38 High Coverage (hg38) 1000 Genome Project data sets. Default is GRCh37 (hg19).
api_root	Optional alternative root url for API.

Value

a data frame

Examples

## Not run: LDmatrix(c("rs3", "rs4", "rs148890987"),
                  "YRI", "r2",
                  token = Sys.getenv("LDLINK_TOKEN"))
                 
## End(Not run)
