Construct a data.frame in a FOR-loop

Say I have a FOR-loop for computing powers (just a trivial example)

for(i in 1:5)
{
x<-i^2
y<-i^3
}

How can I create a data.frame and a 3D plot of (i,x(i),y(i)), i.e. for
each iteration

Thanks,

If thats all you really need:
data<- t(sapply(1:5, function(i){ return(c(i,i^2,i^3))}))
scatterplot3d(data)

In general you don't plot something in R for each iteration.
You rather pass the whole result to the plot function.
But there are plotting function which accept formulas.
