28.16 Adding a Caption and Reference Label
REVIEW We have seen captions and labels above but tell the story here in a slightly different way.
print(xtable(ds,
digits=0,
caption="Selected observations from **weatherAUS**."),
include.rownames=FALSE)Notice that we wanted to emphasise the name of the dataset in the
caption. We can make it bold using the \textbf{} command of
LaTeX within the string passed to caption=. We need to
repeat the backslash because R itself will attempt to interpret it
otherwise. That is, we escape the backslash.
As well as adding a caption with a table number, we can add a label to the xtable::xtable() command and then refer to the table within ``Table ??’’ in the documnet.
print(xtable(ds,
digits=0,
caption="Selected observations from **weatherAUS**.",
label="MyTable"),
include.rownames=FALSE)The references to Table ?? can appear anywhere in the document. We can even refer to its page number by replacing Table ?? on Page .
