Description
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.
