am trying to use a large dataset for ChIPpeakAnno analysis.  A sample of my
bed file looks like

            name chromStart chromEnd strand            chrom
1     NM_001001398   13196926 13203469     -1            chr25
2     NM_001001399    4025604  4033166     -1            chr19
3     NM_001001401   12007237 12036869      1            chr14
4     NM_001001402    8387701  8401691      1            chr22

7     NM_001001407    3585650  3602600     -1            chr15
8     NM_001001409   38023452 38029815      1            chr20
9     NM_001001501    3187183  3217911     -1             chr6

When I use BED2RangedData I get this error:



test.rangedData = BED2RangedData(test.bed)
Error in `rownames<-`(`*tmp*`, value = c("-1", "-1", "1", "1", "-1", "1",  :

 duplicate rownames not allowed
In addition: Warning message:
In BED2RangedData(test.bed) : NAs introduced by coercion

Why is this?
