Vectorize.function: Vectorize a multidimensional Function

Description

Vectorize a d-dimensional (input) function, in the same way that base::Vectorize for 1-dimensional functions.

Usage

Vectorize.function(
  fun,
  dim,
  .combine = rbind,
  .lapply = parallel::mclapply,
  ...
)

Value

a vectorized function (to be called on matrix argument, on each row)

Arguments

fun

'dim'-dimensional function to Vectorize

dim

dimension of input arguments of fun

.combine

how to combine results (default using c(.))

.lapply

how to vectorize FUN call (default is parallel::mclapply)

...

optional args to pass to 'Apply.function()', including .combine, .lapply, or optional args passed to 'fun'.

Examples

f = function(x)x[1]+1; f(1:10); F = Vectorize.function(f,1);
F(1:10); #F = Vectorize(f); F(1:10);

f2 = function(x)x[1]+x[2]; f2(1:10); F2 = Vectorize.function(f2,2);
F2(cbind(1:10,11:20));

f3 = function(x)list(mean=x[1]+x[2],se=x[1]*x[2]); f3(1:10); F3 = Vectorize.function(f3,2);
F3(cbind(1:10,11:20));
