lessR: Less Code, More Results

Each function accomplishes the work of several or more standard R functions. For example, two function calls, rad() and full(), together read the csv data and generate descriptive statistics for all variables in the data frame, plus histograms and bar charts as appropriate. The t-test function, tt, analyzes one or two groups from data or summary statistics and introduces the ODDSMD plot, which displays the Overlapping Density Distributions of two independent groups as well as a visual display of the mean difference and standardized mean difference. Other functions provide for descriptive statistics, a comprehensive regression analysis, color plotting, color bar chart, color histogram, color box plot, color density curves, a calibrated power curve, and the reading and display of csv formatted data. The function help.me provides a help system that suggests specific analyses and functions. Variable labels are also available.
