Add a new R code chunk by clicking the Insert Chunk button on the toolbar

head(cars)
##   speed dist
## 1     4    2

If knitting to html, dataframes with many columns may be paged with rmarkdown:paged_table. Will not work with Word or PDF

#rmarkdown::paged_table(head(cars))

Dataframes in Word and PDF (as well at html) may be alternatively formatted with knitr::kable.

knitr::kable(head(cars))

Output may be displayed without code using echo=FALSE. This is not recommended unless you show the complete code at the end of the document.
