#STAY TUNED
Simple but extensive functionalities for passing R objects to TeX.
I have made extensive use of the xtable and texreg packages, but have ultimately found them too inflexible (see, e.g., 1, 2, 3, 4, 5, etc.) and stale (i.e., it's not typical to be able to propose and implement bug fixes/feature requests with expedience).
Feel free to leave suggested functionalities on the Issues page.
