I am able to replicate your problem, using R 2.7.2:
R version 2.7.2 (2008-08-25)
Copyright (C) 2008 The R Foundation for Statistical Computing
ISBN 3-900051-07-0
...
> source <- read.table("clipboard")
> source
V1 V2 V3 V4 V5 V6 V7
1 HIT000000001 hg18 chr8 + 1759549 1894206 Human
2 HIT000000005 hg18 chr11 - 8593662 8636959 Human
3 HIT000000007 hg18 chr5 + 31675274 32146794 Human
4 HIT000000011 hg18 chr5 + 79739648 79810715 Human
'data.frame': 4 obs. of 7 variables:
$ V1: Factor w/ 4 levels "HIT000000001",..: 1 2 3 4
$ V2: Factor w/ 1 level "hg18": 1 1 1 1
$ V3: Factor w/ 3 levels "chr11","chr5",..: 3 1 2 2
$ V4: Factor w/ 2 levels "-","+": 2 1 2 2
$ V5: int 1759549 8593662 31675274 79739648
$ V6: int 1894206 8636959 32146794 79810715
$ V7: Factor w/ 1 level "Human": 1 1 1 1
Plus/minus signs get read into factor variable V4. If spaces b/w the signs
and the numbers are eliminated, everything works as expected.
