Hi there
In the course of my diploma thesis in climatology I have encountered
a difficult R-Problem that I cannot solve. I want to fill R-Objects
(whose names should depend on j) with numbers at the i-th position.
The resulting Objects should be something like:
RQuadratStep1, RQuadratStep2, RQuadratStep3 ... filled with Elements like
c(0.324, 0.456, 0.657 ...)
Below is a short version of how I have tried to solve it but I don't
know how to insert numbers at the i-th place. The problem seems to be
the "assign" line. Thanks a lot for all hints.
for(j in 1:10) {
for(i in 1:30) {
fit<-lm(annJMSLTv.box~.,data=data.frame(annJMSLTv.box=annJMSLTv.box[,i],allTreerings[,1:15])
backfit<-step(fit,trace=F,steps=1)
assign(eval(parse(text=paste("RQuadratStep",j,sep=""))),round(summary(fit)$r.squared,
dig=3))
}
}

Why don't you want to have RQuadratStep as an array or a list? The problem would vanish then, wouldn't it?
