[Bioc-sig-seq] RangedData: sorting problem

[Zhu, Julie]

Hi,

I am trying to sort a RangedData but encountered the following error. Here
is a toy example to reproduce the error. Did I do something wrong? Thank you
very much for your help!

Best regards,

Julie 

myPeak1 = RangedData(IRanges(start=c(967654, 2010897, 2496704, 3075869,
3123260 ,3857501,201089), end= c(967754, 2010997, 2496804, 3075969, 3123360
,3857601,201089),names=c("Site1", "Site2", "Site3", "Site4", "Site5",
"Site6", "site7")), space=c("1", "2", "3", "4", "5", "6","2"))


myPeak1[order(rownames(myPeak1)),]

Error in myPeak1[order(rownames(myPeak1)), ] :
  cannot combine 'i' row values from different spaces
