coencliner Change Log Version 0.2-3 * Fix an issue related to an upgrade to the *hyperref* LaTeX package that was causing vignette compilation to fail. Reported by: Brian Ripley. Version 0.2-2 * Fix bug in `NegBin()` and `ZINB()` which had incorrect specification of the gamma mixture part of the distribution. Reported by: @nlhuong #24 * Allow for vector `alpha` in `NegBin()` and `ZINB()` Version 0.2-1 * Fix problems identified by `R CMD check` under R-devel Version 0.2-0 * Bug Fix: A typo in the bivariate Beta response function led to the code ignoring `gamma` for the second gradient, which used the value for first gradient instead. Reported by: Jari Oksanen (with patch/fix) * For additional details, please see the github commit log: http://github.com/gavinsimpson/coenocliner/commits/master For higher-level news of chanegs to the package, see the NEWS file. Version 0.1-0 * Released to CRAN... Version 0.0-10 * Gaussian: default for `corr` changed to `0` so users don't need to specify this unless they want correlated responses. * vignette: added a basic tutorial vignette document to the package. * BetaBinomial: realised I should have asked Jari for permission to copy code to compute the parameters of the beta distribution from a parameter tau^2. This came from his BETASIMU C code. I've temporarily removed this code until such a time as I get permission to include it (Jari is in the field). I've replaced it with a different parameterisation I found in Ben Bolker's Ecological Models and Data in R book. Version 0.0-9 * ZIP, ZINB: new wrappers for random number generation for the zero-inflated Poisson (ZIP) and Negative binomial (ZINB) distributions. These functions are simple ZIP and ZINB distributions where the probability of a zero from the binomial part of the model depends only on a mean probability of zero. Version 0.0-8 * Binomial, BetaBinomial: New wrappers for random number generation for the Binomial and Beta-Binomial distributions. The Binomial distribution allows simulation of binomial counts from a probability of occurence and binomial denominator, m, the number of trials (number of individuals counted). The Beta-Binomial() is an extra-variance Binomial distribution and allows simulation of overdispersed binomial count data in a manner similar to that by which the Negative binomial distribution can be used to generate overdispersed Poisson count data. Version 0.0-7 * Beta: now implemented for one or two gradients. Version 0.0-6 * Binomial(): this really should have been Bernoulli and now is. Version 0.0-5 * Old code: This version removed all the `simxDfoo()` functions and associated helpers (`betaResponse()`, `gaussianResponse()`, `biGaussianResponse()`, `expandGauss()`, `expandBeta()`) as these are now no longer needed given that we have `coenocline()` as a gneral interface to all these things. Version 0.0-4 * Gaussian() & Beta() modified to take lists of arguments, `px` and `py`, to simplify the naming of species parameters in these models. * coenocline() modified to supply arguments in the format now required by `Gaussian()` and `Beta()`. Version 0.0-3 * coenocline() a generic interface to coenocline simulation. * Beta(), Gaussian(); new response model functions for the classic Gaussian response model and the generalised Beta response model. * New wrappers for random deviate generation from Poisson, Binomial, and Negative binomial distributions. * expand() a new general version of the expand.grid()-like functionality where we repeat sets of parameters for each of n gradient locations. Version 0.0-2 * added simulators for occurrence not abundance Code provided by F. Rodriguez-Sanchez. Version 0.0-1 * intial alpha version
