A collection of functions for ease of presentation and interpretation of regression analysis. These functions are developed in response to student requests that have arisen in our regression course. For regression diagnostics, see mcDiagnose, getDeltaRsquare, meanCenter or residualCenter. See the outreg function for a way to generate LaTeX tables of regression models. For nice, easy to use pictures, see plotSlopes, plotCurves, plotPlane for graphs. There are some functions for re-organization of data, especially useful might be combineLevels for re-coding factors. The vignette "rockchalk" offers a fairly broad survey. The package title "rockchalk" refers to the expression, "Rock Chalk Jayhawk, Go K.U.".
