Hi,
i am trying to use the normalization function from CGHcall library.

The command i use is

normal.fullData <- normalize(fullData, method = "median", cellularity = 1)

and i get the following error message. How can i solve this issue.

Error in function (classes, fdef, mtable)  :
  unable to find an inherited method for function "copynumber", for
signature "data.frame"

best,
salih
