hello
I make a subroutine that give-me a (mathematical)
function in string format.
I would like transform this string into function ( R
function ).
thanks for any tips.
cleber
#e.g.
fun_String = -100*x1 + 0*x2 + 100*x3
fun - function(x1,x2,x3){
return(
evaluation( fun_String )
fun_String - -100*x1 + 0*x2 + 100*x3
fun - function(x1, x2, x3){
+ eval(parse(text = fun_String))
+ }
fun(4:0, -2:2, 0:4)
[1] -400 -2000 200 400
