Hi the list Is it possible to create an empty matrix ? I do not mean an matrix with a single value that is NA (which is not empty) but a real empty one, with length=0. I do not understand why we have length(numeric()), length(factor()) and length(character()) to zero, and length(array()) to on

Re: [R] empty array

ition will probably works in most case, but in S4, the uses of type is an important point, so I need to use matrix where I shall use matrix, even if it is an empty one. Christophe > --- Christophe Genolini <[EMAIL PROTECTED]> wrote: > > >> Hi the list >> >>

[R] length of S4

Hi the list, With basic type, length gives the length of the vector Wtih list, length gives the number of item With S4 object, length gives...one. Even with an objet with empty slot. setClass("E",representation(e="numeric")) [1] "E" length(new("E")) [1] 1 setClass("E",representation(e="matrix"))

[R] setAs vs setIs

Hi the list I am fighting with the twins setAs and setIs... Here are some questions and comments (comments to myself but that migth be wrong, it is why I am posting them) 1. Very surprising : using setIs define 'is', 'as<-' but not 'as' ??? 2. Using setAs define 'as', 'as<-' but not 'is'... What

Re: [R] setAs vs setIs

I works, great ! So using your code, we can define 'as','as<-' and 'is' with setIt. Is there still any interest using setAs ? Christophe > > It seems to me your problem here is simply that you did not define a > coerce cal in setIs, so it does not know how to turn a C object into a > B object,

[R] S4 : dumpMethod

Hi the list, I almost finished the green book (chapter 7 and 8 on S4), this is probably one of my last question :-) I hope you will not miss them to much ! Here is my today nighmare: I do not manage to use dumpMethod : setClass("A",representation(a="numeric")) setMethod("plot","A",function(x,y,

[R] legend at fixed distance form the bottom

Hi the list I would like to add a legend under a graph but at a fixed distance from the graphe. Is it possible ? More precisely, here is my code : --- 8< symboles <- c(3,4,5,6) dn <- rbind(matrix(rnorm(20),,5),matrix(rnorm(20,2),,5)) listSymboles <- rep(symboles,each=2) matplot(t(dn),pch=

Re: [R] legend at fixed distance form the bottom

Lol. To me, a "fixed amount" that depends on the size of the graph is not much fixed... --- 8< --- symboles <- c(3,4,5,6) dn <- rbind(matrix(rnorm(20),,5),matrix(rnorm(20,2),,5)) listSymboles <- rep(symboles,each=2) layout(matrix(c(1,1,1,2,2,3),3)) for(i in 1:3){ plot(dn) legend("top", pch
