[BioC] NOISeq installation error

[Fatemehsadat Seyednasrollah]

Hi all,
I am trying to install NOISeq package from Bioconductor using commands :
 source("http://bioconductor.org/biocLite.R") 
biocLite("NOISeq")

But there is an error when installing: Warning message: package ‘NOISeq’ is not available (for R version 2.15.1)

But in the manual it is mentioned that NOISeq is available for R (>=2.0.3) so why is that? 
Thanks in advance
