**Sparse Redundancy Analysis** (**sRDA**)

Sparse redundancy analysis for high dimensional (biomedical) data. Directional multivariate analysis to express the maximum variance in the predicted data set by a linear combination of variables of the predictive data set. Implemented in a partial least squares framework, for more details see Csala et al. (2017) <doi:10.1093/bioinformatics/btx374>.

**Helper Functions to Install and Maintain ‘LaTeX’, and Compile ‘LaTeX’ Documents** (**tinytex**)

Helper functions to install and maintain the ‘LaTeX’ distribution named ‘TinyTeX’ (<https://…/> ), a lightweight and portable version of ‘TeX Live’. This package also contains helper functions to compile ‘LaTeX’ documents, and install missing ‘LaTeX’ packages automatically.

**Quantile Regression Forests for ‘ranger’** (**quantregRanger**)

This is the implementation of quantile regression forests for the fast random forest package ‘ranger’.

**Pooled Mean Group Estimation of Dynamic Heterogenous Panels** (**PooledMeanGroup**)

Calculates the pooled mean group (PMG) estimator for dynamic panel data models, as described by Pesaran, Shin and Smith (1999) <doi:10.1080/01621459.1999.10474156>.

**Active Function Cross-Entropy Clustering** (**afCEC**)

Active function cross-entropy clustering partitions the n-dimensional data into the clusters by finding the parameters of the mixed generalized multivariate normal distribution, that optimally approximates the scattering of the data in the n-dimensional space, whose density function is of the form: p_1*N(mi_1,^sigma_1,sigma_1,f_1)+…+p_k*N(mi_k,^sigma_k,sigma_k,f_k). The above-mentioned generalization is performed by introducing so called ‘f-adapted Gaussian densities’ (i.e. the ordinary Gaussian densities adapted by the ‘active function’). Additionally, the active function cross-entropy clustering performs the automatic reduction of the unnecessary clusters. For more information please refer to P. Spurek, J. Tabor, K.Byrski, ‘Active function Cross-Entropy Clustering’ (2017) <doi:10.1016/j.eswa.2016.12.011>.

**Plot Ternary Diagrams** (**Ternary**)

Plots ternary diagrams using the standard graphics functions. An alternative to ‘ggtern’, which uses the ‘ggplot2’ family of plotting functions.
