25.11 Formatting Tables Using Kable
REVIEW Including a typeset table based on a
dataset can be accomplished using knitr::kable(). Here we
will use the larger dataset from
rattle (G. Williams 2021) setting it up as a dplyr::tibble()
courtesy of (Wickham et al. 2021). We will then choose specific columns and a
random selection of rows to include in the table. The source text we
include in our
.Rnw file is listed in the following code
<<example_kable, echo=TRUE, results="asis">>= set.seed(42) library(rattle) nobs <- nrow(weatherAUS) obs <- sample(nobs, 5) vars <- 2:6 ds <- weatherAUS[obs, vars] kable(ds) @
The result (also showing the R code since we specified
TRUE) is then:
# Set the seed so that results are repeatable. set.seed(42) # Load the package from the local library into the R session. library(rattle) # Record metadata for a sample of the dataset. <- nrow(weatherAUS) nobs <- sample(nobs, 5) obs <- 2:6 vars <- weatherAUS[obs, vars] ds # Generate the appropriate LaTeX code to display the data. kable(ds)
Since we are working with a random sample and we would like the sampling to be repeatable we have used base::set.seed() to initialise the random number generator to a fixed value.
