**Experimental Design and Analysis for Tree Improvement** (**eda4treeR**)

Provides data sets and R Codes for Williams, E.R., Matheson, A.C. and Harwood, C.E. (2002). Experimental Design and Analysis for Tree Improvement, CSIRO Publishing.

**Build Dirichlet Process Objects for Bayesian Modelling** (**dirichletprocess**)

Create Dirichlet process objects that can be used as infinite mixture models in a variety of ways. Some examples include; density estimation, Poisson process intensity inference, hierarchical modelling and clustering. See Teh, Y. W. (2011) <https://…/Teh2010a.pdf>, among many other sources.

**Show an Image on an ‘R’ Graphics Device** (**showimage**)

Sometimes it is handy to be able to view an image file on an ‘R’ graphics device. This package just does that. Currently it supports ‘PNG’ files.

**Two Sample Mendelian Randomization using Robust Adjusted Profile Score** (**mr.raps**)

Mendelian randomization is a method of identifying and estimating a confounded causal effect using genetic instrumental variables. This packages implements methods for two-sample Mendelian randomization with summary statistics by using Robust Adjusted Profile Score (RAPS). References: Qingyuan Zhao, Jingshu Wang, Jack Bowden, Dylan S. Small. Statistical inference in two-sample summary-data Mendelian randomization using robust adjusted profile score. <arXiv:1801.09652>.

**Descriptive Analysis by Groups** (**compareGroups**)

Create data summaries for quality control, extensive reports for exploring data, as well as publication-ready univariate or bivariate tables in several formats (plain text, HTML,LaTeX, PDF, Word or Excel. Create figures to quickly visualise the distribution of your data (boxplots, barplots, normality-plots, etc.). Display statistics (mean, median, frequencies, incidences, etc.). Perform the appropriate tests (t-test, Analysis of variance, Kruskal-Wallis, Fisher, log-rank, …) depending on the nature of the described variable (normal, non-normal or qualitative). Summarize genetic data (Single Nucleotide Polymorphisms) data displaying Allele Frequencies and performing Hardy-Weinberg Equilibrium tests among other typical statistics and tests for these kind of data.
