Hi Austin,
If one does need to resort to generating latex code directly from a
language then we have ':results latex', which ensures that the results
are wrapped in a begin_latex block. And as you point out, those R
functions could have their place even in the org-babel framework, as
they can make tabular latex output out of very non-tabular stuff[1]
E.g. below[2].

Footnotes:
[1] Of course it would be better if they generated org tables; maybe we
should start an R package for it (oRg?), one day.
[2] This example summarises a linear regression fit. Neither the printed
representation nor the value of summary(lm(y ~ x)) is at all tabular,
but the xtable function outputs a latex table which can be included in
the org buffer and thus in exported latex.
#+begin_src R :results output latex
library(xtable)
x <- rnorm(100)
y <- x + rnorm(100)
xtable(summary(lm(y ~ x)))
