r2bugs.distributions: convert R parameterizations to BUGS paramaterizations

In dlebauer/r2bugs: R2BUGS distributions

Description

convert R parameterizations to BUGS paramaterizations

Usage

  r2bugs.distributions(priors, direction = "r2bugs")

Arguments

priors	data.frame with columns distn = distribution name, parama, paramb using R default parameterizations
direction,	one of 'r2bugs' (default), 'bugs2r'. Determines if function should convert from R to BUGS, or vice-versa. The bugs2r.distributions does the reverse.

Details

R and BUGS have different parameterizations for some distributions. This function transforms the distributions from R defaults to BUGS defaults. BUGS is an implementation of the BUGS language, and these transformations are expected to work for bugs.

Value

priors dataframe using JAGS default parameterizations

Examples

priors <- data.frame(distn = c('weibull', 'lnorm', 'norm', 'gamma'),
                     parama = c(1, 1, 1, 1),
                     paramb = c(2, 2, 2, 2))
r2bugs.distributions(priors)
