[BioC] limma for R 2.6

[Tiandao Li]

Hello,

I upgraded R from 2.5.1 to 2.6 on Ubuntu this morning. However, when I ran 
normalization using printtiploess, it showed the following error.

> MA2 <- normalizeWithinArrays(RG, method="printtiploess")
Error in .C("lowess", x = as.double(xobs[o]), as.double(yobs[o]), nobs,  :
   C symbol name "lowess" not in DLL for package "base"

However, no error for the next one.

> MA3 <- normalizeWithinArrays(RG, method="printtiploess", weights=weight)

Any suggests are welcome!
