Hello,
Considering 5 points in X-Y plain. Data is a 5*2 matrix (5 rows for samples
& 2 columns for X and Y)
With a distance from the origin, if a distance < 7, remove the row from the
Data.
After calculating the distance for each point, I can't forward because of
this "Removing" problem.
Anyone can help me?
Data=matrix(1:10,5,2)
a=rep(0,5);
b=rep(0,5);
for (i in 1:5))
{
for (k in 1:2)
{
a[i,k]=a[i,k]+(Data[i,k])^2
}
b[i,j]=(a[i,j])^0.5 # distance from the origin
}
Thank you,
Jin
