Hi Jim,
The last question:
I changed my function robustm () to have as output the scatter matrix and
the data to re-enter into the process and I used as suggested you "while
do", and seems to work without errors.
iterate.robustm<-function(x,z) {
b<-robustm(x,z) #in robustm() the output
is a list with [[1]]=scatter matrix [[2]]=my new data
bS<-b[[1]]
finido<-FALSE
while(!finido) {
b2<-robustm(b[[1]],b[[2]])
bS2<-b2[[1]]
for(i in 1:10)
for(j in 1:10)
if(abs(bS2[i,j]-bS[i,j])<=0.001) finido<-TRUE
b<-b2
}
return(b)
}
But my question now is what is the difference between the recursive process
"while do" and suggested earlier with "if else"?
Thank you for all precious tips suggested me
Mary
