Two-way sensitivity analysis (TWSA)

This function runs a deterministic two-way sensitivity analysis (TWSA) on a given function that produces outcomes.

twsa_det(parm1, parm2, ranges, nsamps = 40, params_basecase, FUN,
  outcome, strategies = NULL, ...)

Arguments

parm1	String with the name of the first parameter of interest
parm2	String with the name of the second parameter of interest
ranges	A named list of the form list("parm1" = c(0, 1), ...) that gives the ranges for the parameters of interest. The number of samples from this range is determined by `nsamp`
nsamps	number of parameter values. If NULL, 100 parameter values are used
params_basecase	List with parameters for the base case
FUN	Function that takes `params_basecase` and `...` and produces `outcome` of interest
outcome	String with the outcome of interest produced by `nsamp`
strategies	vector of strategy names. The default (NULL) will use strategy names in FUN
...	Further arguments to FUN (not used)

A dataframe with the results of the sensitivity analysis. Can be visualized with plot.owsa, and owsa_tornado

FUN must return a dataframe where the first column are the strategy names and the rest of the columns must be outcomes.
