Downloads chromosome lengths and centromere positions from the UCSC
Genome Browser for any supported genome assembly. Requires internet
access.
Usage
chr_info_ucsc(genome, autosomes_only = TRUE)
Arguments
- genome
UCSC genome identifier, e.g. "hg38", "mm39",
"bosTau9", "canFam6", "susScr11", "galGal6".
- autosomes_only
If TRUE (default), return only autosomal
chromosomes (exclude X, Y, M, and unplaced scaffolds).
Value
A data.frame with columns: chr (integer), length,
centromere_start, centromere_end.
Examples
if (FALSE) { # \dontrun{
# Dog genome
dog <- chr_info_ucsc("canFam6")
snp_density(gwas, chr_info = dog)
# Pig genome
pig <- chr_info_ucsc("susScr11")
} # }
