I was wondering how to make a function which minimises a vector (a,b,c,d).
I have an equation ( for simplicity) say its 5 -(3a+4b+6c+8d) and i want to
make this equation as small as possible. Thus need to find the values for a b c
and d for which this happens.
I know there is a function in r
Your script is rather inefficient with spurious cbind calls. Any
particular reason not to use
?ar directly ?
