coenocliner 0.2-3 ================= * Fix an issue causing vignette compiling to fail due to an update to the LaTeX package *hyperref*. Reported by: Brian Ripley. coenocliner 0.2-2 ================= * `NegBin()` and `ZINB()` incorrectly specified the gamma part of the distribution. The `shape` argument to `rgamma()` should have been `1/alpha` where `alpha` was used previously. Also clarified the paramterization of the negative binomial used by `NegBin()` and `ZINB` as the NB2 version. * `NegBin()` and `ZINB()` allow for vector `alpha` inputs. #25 coenocliner 0.2-1 ================= * Minor package update to fix issues under `R CMD check` in the development version of R. coenocliner 0.2-0 ================= * Jari Oksanen is now listed as a contributor to the package having added several new stochastic distributions. * The object returned by `coenocline()` now has S3 class `"coenocline"` and inherits from the `"matrix"` class. * A `print()` method has been added for `coenocline()` which displays some summary information and the first `n` lines of the simulated counts. The `print()` method uses a new internal function modelled on the way **dplyr** prints data frames. * A `stack()` method for `coenocline()` was added. This makes it much easier to reshape the simulated count data into a format suitable for use with **ggplot** or **lattice** graphics, or R's modelling functions. * An enhanced `plot()` method for `coenocline()` objects is provided, which can draw 1-d plots of single gradient simulations. * A `persp()` method is now provided which can produced 3-d perspective plots od simulations with 2 gradients. * Two new stochastic distributions were added by Jari Oksanen - Zero-inflated Binomial - Zero-inflated Beta-binomial * A new extractor function is provided, `locations()`, which extracts the gradient locations at which counts were simulated. Bug fixes --------- * Jari Oksanen noticed an annoying but important bug in the 2D Beta response function; the `gamma` parameter for the second gradient was being ignored, and the value of `gamma` for the first gradient was used instead. coenocliner 0.1-0 ================= * An R package for coenocline simulation; generating simulated species abundance or occurence data along one or two gradients * First public release of coenocliner on CRAN * Species response can be parameterised using either the classic Gaussian response model or the generalise beta response model * Random count or occurence data can be simulated from species responses using random draws from a Poisson, Negative Binomial, Binomial, Beta-binomial, ZIP, ZINB, or Bernoulli distribution with the parameterised response curve taken as the mean or expectation of the distribution to draw from * The main user-facing function is `coenocline()`. See `?coenocliner` and `?coenocline` for further details and examples of usage * A basic overview and introductory tutorial for coenocliner is available.
