I have a bed file like this

ChrIII_A_nidulans_FGSC_A4   0   10  0.83700
ChrIII_A_nidulans_FGSC_A4   10  43  1.11600
ChrIII_A_nidulans_FGSC_A4   43  59  1.39500
ChrIII_A_nidulans_FGSC_A4   59  65  1.67400
ChrIII_A_nidulans_FGSC_A4   65  74  1.95300

As you can see there are no Strand name columns or Strand orientation column. If I try to import this file into R, it calls the score column as the name column

library(GenomicRanges)
library(rtracklayer)
library(IRanges)
file <- import.bed(file.path('C:/Users/ami/Downloads', file.bdg'))

The output for this is below

GRanges object with 4233716 ranges and 1 metadata column:

    seqinfo: 9 sequences from an unspecified genome; no seqlengths

My overall objective is to create a TSS line plot using this bed file. How can I load a bed file properly in rtracklayer and ignore these columns?
