Uploading bed3 format into Guitar package in R

Question

[blur]

Hi,

I want to upload bed3 format to R for a guitar plot I followed the manual which states:

> bed3=system.file("extdata", "H3K4me3_mm10_1000peaks.bed", package="Guitar")

but when I open the bed3 file [head(bed3)] - this file is empty. Any ideas what I am doing wrong? Thanks!

figured it out: you can skip this step and go straight to bed3 <- import.bed("file.bed")
