Scaling a numeric matrix in R with values 0 to 1

Question

Here is an excerpt of numeric matrix that I have

 [1,]   30 -33.129487   3894754.1 -39.701738 -38.356477 -34.220534
 [2,]   29 -44.289487  -8217525.9 -44.801         


        

Answer 1

And if you were still to use scale:

maxs <- apply(a, 2, max)
mins <- apply(a, 2, min)
scale(a, center = mins, scale = maxs - mins)
