The rmarkdown package will call the knitr package. You can transform an R Markdown file in two ways. R Markdown files are the source code for rich, reproducible documents. rmarkdown comes installed with the RStudio IDE, but you can acquire your own copy of rmarkdown from CRAN with the command install.packages("rmarkdown") R Markdown files are designed to be used with the rmarkdown package. Note that the `echo = FALSE` parameter was added to the code chunk to prevent printing of the R code that generated the plot.
