Tools to Analyze Repertory Grid Data (OpenRepGrid)
Analyze repertory grids, a qualitative-quantitative data collection technique devised by George A. Kelly in the 1950s. Today, grids are used across various domains ranging from clinical psychology to marketing. The package contains functions to quantitatively analyze and visualize repertory grid data (see e.g. Bell, 2005, <doi:10.1002/0470013370.ch9>; Fransella, Bell, & Bannister, 2004, ISBN: 978-0-470-09080-0).

Partial Least Squares Regression for Beta Regression Models (plsRbeta)
Provides Partial least squares Regression for (weighted) beta regression models and k-fold cross-validation of such models using various criteria. It allows for missing data in the explanatory variables. Bootstrap confidence intervals constructions are also available.

Time Series Plot (rtsplot)
A fast and elegant time series visualization package. In addition to the standard R plot types, this package supports candle sticks, open-high-low-close, and volume plots. Useful for visualizing any time series data, e.g., stock prices and technical indicators.
