Hi everybody! I have a matrix of class "myClass", for example: myMat<- matrix(rnorm(30), nrow = 6) attr(myMat, "class")<- "myClass" class(myMat) When I extract part of ''myMat'', the corresponding class ''myClass'' unfortunately disappear: myMat.p<- myMat[,1:2] class(myMat.p) Please for any advice / suggestions, how define class, that during an operation does not disappear.
You will need a "[" method for your class. Uwe Ligges
