Search the current working directory for a file or directory matching the input name, and if it exists suggest a new name by appending a counter to the input name.  Alternatively, the function can ask the user if the existing file should be overwritten, in which case the existing file will be erased if the answer is 'yes'.  The function also checks for write access permissions at the current working directory.  Used by the bayescount function.

methods

new_unique

A set of functions to apply a (zero-inflated) gamma Poisson (equivalent to a negative binomial), (zero-inflated) simple or independant Poisson, (zero-inflated) lognormal Poisson or (zero-inflated) Weibull Poisson model to a set of count data using JAGS (Just Another Gibbs Sampler).  Returns information on the possible values for mean count, variance and zero inflation present in count data such as faecal egg count data.  Checks for convergence using the Gelman-Rubin statistic.  Likelihoods for the above distributions can also be calculated, and a crude maximum likelihood function is included.  Also allows any user specified model to be run in JAGS from within R, returning the MCMC output as R objects.  Just Another Gibbs Sampler (JAGS) must be installed.  *THIS SOFTWARE IS INTENDED FOR EDUCATIONAL PURPOSES ONLY AND SHOULD NOT BE RELIED UPON FOR REAL WORLD APPLICATIONS*
