lessR (2.5)

Less Code, More Results.


Each function accomplishes the work of several or more standard R functions. For example, two function calls, Read() and CountAll(), read the data and generate descriptive statistics for all variables in the data frame, plus histograms and bar charts as appropriate. Other functions provide for descriptive statistics, a comprehensive regression analysis, ANOVA and t-test, color plotting, color bar chart, color histogram, color box plot, color density curves, a calibrated power curve, and the reading and display of csv and other formatted data. The function Help provides a help system that suggests specific analyses and functions. Variable labels, and color themes with the set function, are also available. A confirmatory factor analysis of multiple indicator measurement models is also available as well as pedagogical routines for data simulation such as for the Central Limit Theorem.
