[BioC] function log2ratios() missing in snapCGH ?

[Winfried Hofmann]

Dear colleagues,

on my new R-2.9.0 /Bioconductor 2.4-Installation, I get an error
message when using the function processCGH():
"Error in ncol(log2ratios(MA)) : could not find function "log2ratios"".
Unlike the former version of Bioconductor, the function log2ratios()
seems to be missing in the current version.

Maybe somebody knows more about it.

Thanks in advance

Winfried Hofmann
