ssdtools - Species Sensitivity Distributions

Species sensitivity distributions are cumulative probability distributions which are fitted to toxicity concentrations for different species as described by Posthuma et al.(2001) <isbn:9781566705783>. The ssdtools package uses Maximum Likelihood to fit distributions such as the gamma, log-logistic, log-normal and log-normal log-normal mixture. Multiple distributions can be averaged using Akaike Information Criteria. Confidence intervals on hazard concentrations and proportions are produced by parametric bootstrapping.

ypr - Yield Per Recruit

An implementation of equilibrium-based yield per recruit methods. Yield per recruit methods can used to estimate the optimal yield for a fish population as described by Walters and Martell (2004) <isbn:0-691-11544-3>. The yield can be based on the number of fish caught (or harvested) or biomass caught for all fish or just large (trophy) individuals.

nlist - Lists of Numeric Atomic Objects

Create and manipulate numeric list ('nlist') objects. An 'nlist' is an S3 list of uniquely named numeric objects. An numeric object is an integer or double vector, matrix or array. An 'nlists' object is a S3 class list of 'nlist' objects with the same names, dimensionalities and typeofs. Numeric list objects are of interest because they are the raw data inputs for analytic engines such as 'JAGS', 'STAN' and 'TMB'. Numeric lists objects, which are useful for storing multiple realizations of of simulated data sets, can be converted to coda::mcmc and coda::mcmc.list objects.

universals - S3 Generics for Bayesian Analyses

Provides S3 generic methods and some default implementations for Bayesian analyses that generate Markov Chain Monte Carlo (MCMC) samples. The purpose of 'universals' is to reduce package dependencies and conflicts. The 'nlist' package implements many of the methods for its 'nlist' class.

mcmcderive - Derive MCMC Parameters

Generates derived parameter(s) from Monte Carlo Markov Chain (MCMC) samples using R code. This allows Bayesian models to be fitted without the inclusion of derived parameters which add unnecessary clutter and slow model fitting. For more information on MCMC samples see Brooks et al.

newdata - Generate New Data Frames for Prediction

Generates new data frames for predictive purposes. By default, all specified variables vary across their range while all other variables are held constant at the default reference value. Types, classes, factor levels and time zones are always preserved. The user can specify the length of each sequence, require that only observed values and combinations are used and add new variables.

err - Customizable Object Sensitive Messages

Messages should provide users with readable information about R objects without flooding their console. 'cc()' concatenates vector and data frame values into a grammatically correct string using commas, an ellipsis and conjunction. 'cn()' allows the user to define a string which varies based on a count. 'co()' combines the two to produce a customizable object aware string. The package further facilitates this process by providing five 'sprintf'-like types such as '%n' for the length of an object and '%o' for its name as well as wrappers for pasting objects and issuing errors, warnings and messages.

batchr - Batch Process Files

Processes multiple files with a user-supplied function. The key design principle is that only files which were last modified before the directory was configured are processed. A hidden file stores the configuration time and function etc while successfully processed files are automatically touched to update their modification date. As a result batch processing can be stopped and restarted and any files created (or modified or deleted) during processing are ignored.

rescale - Rescales Data Based on Other Data

Rescales columns in a data frame based on the columns in a second data frame. For example a column can be rescaled by subtracting the mean and dividing by the standard deviation. The user can pass the names of functions which calculate the value to subtract and/or the value to divide by. The package was developed for making predictions based on models with rescaled variables. For the predictions to be valid the new data frame must have its predictor variables rescaled based on the original data.

gsdd - Calculate Growing Season Degree Days from Water Temperature Data

Calculates Growing Season Degree Days (GSDD), Growing Degree Days (GDD) and the Growing Seasons (GSS) from water temperature data. GSSD is a water temperature metric that is a useful predictor of age-0 trout size at the beginning of winter. It is the accumulated thermal units (in C) during the growing season based on the mean daily water temperature values. GDD is the GSSD to a particular date.

Six relational 'tibbles' from the Kootenay Lake Large Trout Exploitation study. The study which ran from 2008 to 2014 caught, tagged and released large Rainbow Trout and Bull Trout in Kootenay Lake by boat angling. The fish were tagged with internal acoustic tags and/or high reward external tags and subsequently detected by an acoustic receiver array as well as reported by anglers. The data are analysed by Thorley and Andrusak (1994) <doi:10.7717/peerj.2874> to estimate the natural and fishing mortality of both species.
