The knitr::kable() function does some internal setup, including
determining the target format, and then calls an internal function using
do.call(paste("kable", format, sep = "_"), list(x = x,
caption = caption, escape = escape, ...))
I was interested in setting the `vlign` argument to knitr:::kable_latex,
using this code:
knitr::kable(head(mtcars), format="latex", align = "c",
vlign="")
If I debug knitr::kable, I can see that `vlign = ""` is part of
list(...). However, if I debug knitr:::kable_latex, I get weird results:
> debug(knitr:::kable_latex)
> knitr::kable(head(mtcars), format="latex", align =
"c", vlign="")
debugging in: kable_latex(x = c("Mazda RX4", "Mazda RX4
Wag", "Datsun
710",
"Hornet 4 Drive", "Hornet Sportabout",
"Valiant", "21.0", "21.0",

escape = TRUE, vlign = "")
debug: {
[rest of function display omitted]
I see here that vlign = "" is being shown as an argument. However,
when
I print vlign, sometimes I get "object not found", and somethings I
get
Browse[2]> vline
debug: [1] "|"
(which is what the default value would be). In the latter case, I also see
Browse[2]> list(...)
$vlign
[1] ""
i.e. vlign remains part of the ... list, it wasn't bound to the argument
named vlign.
I can't spot anything particularly strange in the way knitr is handling
this; can anyone else? My sessionInfo() is below.

Sorry, it's a silly thinko. I misspelled the vline argument. Thanks Ivan for the gentle nudge!
