lessR

less work, more results for data analysis with R

The functions in the lessR R package provide many of the most common data analyses, each obtained with a simple function call. In general, an analysis consists of both one or more visualizations as well as statistical output. Most data analytic lessR function calls provide both. Some examples of just the visualization output follow, with the accompanying function calls. The optional style function provides options beyond the default styling.

  • library("lessR")
  • d <- Read("Employee")
  • Histogram(Salary)
  • BarChart(Dept)

 

  • library(lessR)
  • d <- Read("Mach4")
  • style("orange",
       sub_theme="black")
  • Plot(m06)
  • Plot(m06, m07,
       ellipse=TRUE,
       fit="loess")

This site provides support for doing data analysis with the R program using the functions in the package lessR, as documented by the accompanying text.

lessR 4.0.1 Vignettes

These vignettes, downloaded with lessR but also available on the web, provide detailed examples and explanation of various lessR functions. The Proportions tests are new to this version of lessR, and the pivot function features have been much increased.
