Formatting Tables Using Kable
Raw Including a typeset table based on a dataset can be accomplished using knitr::kable(). Here we will use the larger weatherAUS dataset from rattle setting it up as a dplyr::tibble() courtesy of dplyr. 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 block.
The result (also showing the R code since we specified echo=TRUE) is then:
# Set the seed so that results are repeatable.
# Load the package from the local library into the R session.
# Record metadata for a sample of the dataset.
nobs <- nrow(weatherAUS)
obs <- sample(nobs, 5)
vars <- 2:6
ds <- weatherAUS[obs, vars]
# Generate the appropriate LaTeX code to display the data.
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.
