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.
