Display R-Code in Output[edit]

In general the R-code is not echoed in the output. If you want to view the code chunks for debugging set echo = FALSE. {r setup, include=FALSE} knitr::opts_chunk$set(echo = FALSE)

Output Format[edit]

If you want to change the output format, * OFFICE - LibreOffice Write/Word: change the output: setting in header to output: word_document. * PRESENTATION - Web: change the output: setting in header to output: ioslides_presentation: default.
