script S-plus -> R
Dear List,
I'm trying to transfer a script that uses S-plus functions for the
kernel and integration calculations to R. This it what it looks like in
S-plus:
qrm(cpt,don,ect,h,intctk,nbcol,nbl1,nbl2,nbl3,nlc,nlgn,overlap,Results,tdon,tdon1,tdon11,tdon2,tdon21)
don<-guiDisplayFileDialog()
import.data (DataFrame="tdon",FileName=don,FileType="EXCEL")
nbcol<-length(tdon[1,])
nlc<-matrix(0,1,nbcol)
for (i in 1:nbcol)
{nbl1<-tdon[,i]
nbl2<-nbl1[nbl1!="NA"]
nbl3<-numRows(nbl2)
nlc[,i]<-nbl3
ect...

doubt with integrate ()
...t; function. Searching in the r-help
archives, I think this may have something to do with the function (it is not
returning a vector but a number), but I don't see exactly what.
The function to integrate was defined with a for loop first:
for (i in 1:(nbcol-1))
{tdon1<-tdon[,i]
tdon11<-subset(tdon1,tdon1!="NA")
fctk1<-function(x)
{density(tdon11, bandwidth=h[i], kernel="gaussian")$y}
for (j in (i+1):nbcol)
{tdon2<-tdon[,j]
tdon21<-subset(tdon2,tdon2!="NA")
fctk2<-function(x)
{density(tdon21,bandwidth=h[j],...

script problem to obtain pairs of overlap values
...f script.
tdon <- data.frame (sp.1=c (5 ,9 ,NA ,5, 11) , sp.2=c (4, 2, 4, NA, 11,
),sp.3=c(5, 4, 2, 6, 13), sp.4=c(3 , 11, NA, 5, 3), sp.5=c(2 ,5 ,2, 9, 9))

Here is the code:

{tdon1<-tdon[,i]
tdon11<- subset(tdon1,tdon1!="NA")
