===xtable=== Each time you want to generate LaTeX code for a table in your document, you need to use knitr to create an R environment and use the xtable package. For instance, printing the summary stats table from the example above would look like this: <<summary stats, echo=FALSE, message=FALSE, results='asis'>>= print(xtable(summary.stats, caption = "Summary statistics.", label="table:descriptives", align="llrrr"), include.rownames=FALSE) @ Note that there's a funny thing going on with the <code>align</code> parameter here. R includes some default rownames for dataframes (usually something like X1, X2 etc). Since we have a column that contains our rownames, we need to suppress the default rownames by specifying <code>include.rownames=FALSE</code>. However, even though the <code>summary.stats</code> dataframe contained only four columns, we still need to specify ''five'' column alignments in for the <code>align</code> parameter because the first one corresponds to the default rownames column in the R dataframe. Not specifying the extra column alignment parameter will give you an error.
