Building a beamer presentation with knitr.

Introduction

The documents included are the input for knitr. In addition you need to have the tool pandoc installed. I also use a custom beamer template to add the University of Utah \institute command to the template. It also changes the indentation some.

Steps

1. knit document with

halpo

margins <- 
    function( grouped               #< [grouped_df] A data frame with groups defined.
            , ...                   #< passed to `FUN`
            , FUN=dplyr::summarize  #< Summary function
            , all.name = getOption("margins::all.name", "(All)")
            ){
    "Add margins to summarization"
    g <- groups(grouped)
    com <- lapply(seq(0, length(g)), combn, x=g, simplify=FALSE)
    com <- Reduce(c, com)
