10.1.7 Escape special characters

If you are familiar with HTML or LaTeX, you know that there are a few special characters in these languages. To generate safe output, kable() will escape these special characters by default via the argument escape = TRUE, which means all characters will be generated verbatim, and special characters lose theirspecialmeanings. For example,> will be substituted with > for HTML tables, and _ will be escaped as \_ for LaTeX tables. If you are an expertand know howtouse special charactersproperly, you may disable this argument via escape = FALSE. In the second table below, we include a few LaTeX math expressions that contain special characters $, \, and _:

m <- lm(dist ~ speed, data = cars)

d <- coef(summary(m))

knitr::kable(d)
