If I understood correctly what you want, one possibility is to use the "xtable" package to return an R object in the latex table format.

A solution using the stargazer package is:

install.packages("stargazer")
library(stargazer)

data("iris")
stargazer(do.call(cbind, lapply(iris,summary)), type = "latex")
