Dear all,
I created a function which it has many arguments i.e. Mu(x, Y, B, X, P)
where Mu is the function. This function works perfect but when I am trying
to use it in the apply() function in the manner apply(Matr, 1, Mu, Y=y, B=b,
X=x, P=p) it does not work and the output is: Error in match.fun(FUN) : '1'
is not a function, character or symbol
When I transform the function Mu to have less arguments like Mu(x, DATA) and
use apply by apply(Matr, 1, Mu, DATA=data) it works perfect
Does anyone knows where is my mistake?
The arguments of apply are
> args(apply)
function (X, MARGIN, FUN, ...)
so you actually called apply(X=x, MARGIN=Matr, FUN=1, Y=y, B=b, P=p)
Thanks
Dimitris
