Set default for Gamma priors
default_priors()
a list of default parameters for the priors. Values can then be manually be edited as in the examples below. Users could use functions `epitrix::gamma_shapescale2mucv` and `epitrix::gamma_mucv2shapescale` to set the shape and scale corresponding to the desired prior mean and coefficient of variation.
priors <- default_priors()
# change the prior for R to have a mean of 3
priors$R$shape <- 3
