Examples

require(GenomicRanges)
brain.file <- system.file("extdata", "eqtl/brain.gtex.txt", 
    package="loci2path")
tab <- read.table(brain.file, stringsAsFactors=FALSE, header=TRUE)
eqtlRange <- GRanges(seqnames=Rle(tab$snp.chr), 
    ranges=IRanges(start=tab$snp.pos, 
    width=1))
brain.eset <- eqtlSet(tissue="brain",
    eqtlId=tab$snp.id,
    eqtlRange=eqtlRange,
    gene=as.character(tab$gene.entrez.id))
tissue(brain.eset)
head(eqtlId(brain.eset))
eqtlRange(brain.eset)
head(eqtlGene(brain.eset))
