In xiaoyuezhuu/risky-muscimol: Makes plots for the risky paper on bioRxiv

returns choice_prob (probability choosing lottery) or choice (binary) from the simulated three-agent rho-sigma agent

rho_sigma_agent(
  prob = FALSE,
  params,
  sb_mag,
  lottery_mag,
  lottery_prob,
  total_rew_multi
)

`prob:`	Boolean, if true returns choice_prob
`params:`	a list as in list('rho' = 1, 'sigma' = 0.4, 'omega' = c(0.8, 0.1, 0.1))
`sb_mag:`	a vector of n_trials with surebet magnitude
`lottery_mag:`	a vector of n_trials with lottery magnitude
`lottery_prob:`	a vector of n_trials with lottery probability
`total_rew_multi:`	a vector of n_trials with total reward multiplier
