Hello, Alaios,take a look at the help page of ecdf() where it says that the result of ecdf(x) is a 'function (!) of class "ecdf"', not a vector of function values.
Take a look at what
1- ecdf(onVector)(onVector)
does, and maybe
myecdfOn <- function( x) { 1- ecdf(x)(x)}
followed by
myecdfOn( OnVector)
does what you want, and can finally be input to curve(). HtH -- Gerrit On Tue, 24 Apr 2012, Alaios wrote:
Dear all, I would like to calculate the complementary cumulative distribution function. As it is known, the ccdf is the 1-ecdf(X)==1-F(x). (From ?ecdf help is shown that ecdf returns a function which is the F(x)I would like to use that function inside my function and after call curve (which accepts function as input). My code looks like thatonVector<-seq(1:100) offVector<-seq(101:200) myecdfOn<-function(onVector){1-ecdf(onVector)} # This gives the ccdf curve(myecdfOn,from=1,to=max(c(onVector,offVector)), add=TRUE,lwd=2) Unfortunately fails and I can not really see what is he problem of it. Could you please help me?
