Description Usage Arguments Details Author(s) Examples

The sfcr_expand() function is a s3 generic that takes a list of external objects and returns a expanded set of these lists. It has methods for sfcr_set objects and for sfcr_shock objects.

1	sfcr_expand(x, variable, values)

`x`	A external set created with `sfcr_set()` or a shock set created with `sfcr_shock()`
`variable`	the name of variable to be expanded.
`values`	a vector containing the new values of the external or shock variable.

There are two available methods for the sfcr_expand() function:

sfcr_set: Takes a sfcr_set object with external variables and creates a list of sets that inherits all the aspects of the x set supplied but set the values of the variable to the each element of value. The output is a sfcr_mlt_set object.
sfcr_shock: Takes a sfcr_shock object and creates a list of shocks that inherits all the aspects of the x shock but set the values of the variable to each element of value. The output of this method is a sfcr_mlt_shock object.

# 1. Expand a external set:
external <- sfcr_set(G_d ~ 20, W ~ 1, alpha1 ~ 0.6, alpha2 ~ 0.4, theta ~ 0.2)
sfcr_expand(external, alpha2, c(0.1, 0.2))

# 2. Expand a shock:
shock <- sfcr_shock(variables = sfcr_set(alpha1 ~ 0.8), start = 5, end = 50)
sfcr_expand(shock, alpha1, c(0.7, 0.8, 0.9))
