HTTP Error Helpers (fauxpas)
HTTP error helpers. Methods included for general purpose HTTP error handling, as well as individual methods for every HTTP status code, both via status code numbers as well as their descriptive names. Supports ability to adjust behavior to stop, message or warning. Includes ability to use custom whisker template to have any configuration of status code, short description, and verbose message. Currently supports integration with ‘crul’, ‘curl’, and ‘httr’.

Random Sampling Association Rules from a Transaction Dataset (RSarules)
Implements the Gibbs sampling algorithm to randomly sample association rules with one pre-chosen item as the consequent from a transaction dataset. The Gibbs sampling algorithm was proposed in G. Qian, C.R. Rao, X. Sun and Y. Wu (2016) <DOI:10.1073/pnas.1604553113>.

Confidence Intervals for Comparisons of Binomial or Poisson Rates (ratesci)
Computes confidence intervals for the rate (or risk) difference (‘RD’) or ratio (‘RR’) for independent binomial proportions or Poisson rates, or for odds ratio (‘OR’, binomial only). Also confidence intervals for a single binomial or Poisson rate. Includes asymptotic score methods including skewness corrections, which have been developed from Miettinen & Nurminen (1985) <doi:10.1002/sim.4780040211> and Gart & Nam (1988) <doi:10.2307/2531848>. Also includes MOVER methods (Method Of Variance Estimates Recovery), derived from the Newcombe method but using equal-tailed Jeffreys intervals. Also methods for stratified calculations (e.g. meta-analysis), either assuming fixed effects or incorporating stratum heterogeneity.

R6 Objects for Text and Data (rtext)
For natural language processing and analysis of qualitative text coding structures which provide a way to bind together text and text data are fundamental. The package provides such a structure and accompanying methods in form of R6 objects. The ‘rtext’ class allows for text handling and text coding (character or regex based) including data updates on text transformations as well as aggregation on various levels. Furthermore, the usage of R6 enables inheritance and passing by reference which should enable ‘rtext’ instances to be used as back-end for R based graphical text editors or text coding GUIs.

Read HTTP Archive (‘HAR’) Data (HARtools)
The goal of ‘HARtools’ is to provide a simple set of functions to read/parse, write and visualise HTTP Archive (‘HAR’) files in R.
