Knitr Kable Table not producing captions in R markdown

I've read the various posts on this subject but am still having an issue. I can produce a nice-looking table when exporting to pdf or html, but it doesn't include the caption!

row1 <- c("a", "b", "c")
row2 <- c("d", "e", "f")
data <- as.data.frame(rbind(row1, row2))
kable(data, caption = "head")

If I try to run the code, I don't get the desired caption.

I think it might have something to do with the packages that are installed? 

library(httr)
library(dplyr)
library(scales)
library(tidyverse)
library(jsonlite)
library(skimr)
library(lubridate)
library(AER)
library(MASS)
library(countreg)

knitr::opts_chunk$set(tidy.opts=list(width.cutoff=60),tidy=TRUE)
knitr::opts_chunk$set(echo = TRUE)
Solution

  • I figured out that I had to load the knitr package at the beginning of the RMD file. Then, the caption appeared. Thanks!
