density(x)
...with imported data from either EXCEL or text files:
Error in density(spr) : argument must be numeric.
Other procedues such as truehist work. If I generate data within R density works fine.
Does anybody have an idea?
Yours

Construct a data.frame in a FOR-loop
...puting 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,
Serguei Kaniovski
