26.13 Improvements Using BookTabs

REVIEW The booktabs package for LaTeX provides additional functionality that we can make use of with knitr::kable(). To use this be sure to include the following in the preamble (before the \begin{document} of your .Rnw file:

# Load the package from the local library into the R session.

\usepackage{booktabs}

We can then set booktabs=TRUE to remove the clutter of the extra lines.

# Use the booktabs option to improve presentation of the table.

ds %>% kable(row.names=FALSE, digits=0, booktabs=TRUE)

Location	MinTemp	MaxTemp	Rainfall	Evaporation
Tuggeranong	10	25	0	NA
Wollongong	21	31	1	NA
Dartmoor	6	15	2	3
Sale	17	29	0	6
WaggaWagga	8	31	0	4

In the following example we notice that with more rows booktabs=TRUE will add a small gap every 5 rows.

# Display a tale with more observations.

weatherAUS[sample(nobs, 12), vars] %>%
  kable(row.names=FALSE, digits=0, booktabs=TRUE)

Location	MinTemp	MaxTemp	Rainfall	Evaporation
