Using knit2pdf with Rmd files

Question

Is it possible to use the knitr function knit2pdf() directly with R Markdown (Rmd) files? I've seen various tutorials/class notes that seem to suggest it can e.g. here and here (Ctrl+F "knit2pdf" in either). But when I take a simple rmd file (saved as "test.rmd") ```` --- title: "knit2pdf test" author: "A Aaronson" date: "Thursday, February 19, 2015" output: pdf_document --- This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see <http://rmarkdown.rstudio.com>. When you click the **Knit** button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this: ```{r} summary(cars) ``` You can also embed plots, for example: ```{r, echo=FALSE} plot(cars) ``` Note that the `echo = FALSE` parameter was added to the code chunk to prevent printing of the R code that generated the plot.…

Accepted Answer

Your input file is in `rmarkdown` format.

You should use the `render()` function in the `rmarkdown` package to compile your document.

Try:

```
library("rmarkdown")
render("temp.rmd")
```
