Estoy ejecutando un script en R usando el comando: Rscript gtextisschrom.R 1
El contenido de este script es:

source(“../code/gtex_v7_nested_cv_elnet.R”)
“%&%” <- function(a,b) paste(a,b, sep=”)

argv <- commandArgs(trailingOnly = TRUE)
chrom <- argv[1]

#tiss <- argv[1]
#chrom <- argv[2]

main(snp_annot_file, gene_annot_file, genotype_file, expression_file, covariates_file, as.numeric(chrom), prefix, null_testing=FALSE)
