search for: imputemyobj

.... At some point, I would like to impute the missing value in the matrix. So I would like to use something like : ----------------- setClass("MyObj",representation(time="numeric",traj="matrix")) a <- new("MyObj",time=3,traj=matrix(c(1:6,NA,8:12),ncol=3)) imputeMyObj(a) ----------------- I find 'setTime<-' to change le slot time, but it can not work in the case of imputeMyObs since this mehod does not need a value... Any solution ? Thanks Christophe
