Hi there,
I have a vector of some functions e.g.
#-----------------------------#
f.1 <- function(a) {
return( a );
}
f.2 <- function(a) {
return( 1 - (tanh(a))^2 );
}
f.3 <- function(a) {
return( 1 / (1+exp(-a)) * (1 - (1 / (1+exp(-a)))) );
}
func.l <- c(f.1, f.2, f.3);
#-----------------------------#
and would like to calculate the output value of a function in the
vector, that is, pick e.g. function at position 2 in func.l and calculate the
output value for a=42.
func.l[2](42); # gives error
f <- func.l[2];
f(42); # gives error
Is there an easy way to solve this problem?
Cheers,
Thomas
