A small code bug

[DJEKIDEL MOHAMED NADHIR]

Hi, 

Thanks for the package, 

Recently I have been using the package and after running the following command 

 H3K4me1_bin <- readBins(type=c("chip","input","GC","N"), fileName=c(H3K4me1, input, GCcontent, NNcontent))

I got the following error :  

Error in intersect(chrChIP, chrInput, chrN)

I went through the code ReadBins and changed line 167 to 

Reduce(intersect, list(chrChIP, chrInput, chrN))

And every thing worked fine, 

maybe it would be nice to fix the bug :)

Regards
