1. confbars

Add confidence bars to linear model plots

confbars(model, xbounds=range(model$model[,2]), level=.95, ...)

• model an object containing the results returned by a model fitting function (e.g., lm or glm).
• xbounds left-right limits on the lines to be drawn.
• level float (0,1); the confidence level, defaults to 0.95.

Example Usage

confbars(mod1, lty=2, col='red')

2. roller

Roll any number of dice any number of times apiece

roller(sides_vec, rolls_vec)

• sides_vec vector where each element is a number of sides of a die
• rolls_vec vector of times to roll each corresponding die

Example Usage

> roller(c(6,12,20), 1:3)
$`6-sided`
[1] 5

$`12-sided`
[1] 12 11

$`20-sided`
[1]  3 18 20

6. Installation

# devtools lets you install packages from GitHub:
install.packages('devtools')
library(devtools)

# then it's this simple:
install_github('vlahm/statextra')
library(statextra)
