I found this blog on getting a nested table into LaTeX format[(Blog Link)](http://www.r-statistics.com/2012/01/printing-nested-tables-in-r-bridging-between-the-reshape-and-tables-packages/). I like the outcome but want to insert a column into the object at the beginning after the rownames. I'm used to dealing with data frames so dealing with this beast is more difficult than typical column indexing. Here's what I have now: pre post approach mean sd mean sd 1 24.17 8.310 54.33 11.01 2 25.50 9.434 65.25 16.32 3 26.33 9.139 63.17 12.53 And here's what I'd like it to look like: pre post approach n mean sd mean sd 1 12 24.17 8.310 54.33 11.01 2 12 25.50 9.434 65.25 16.32 3 12 26.33 9.139 63.17 12.53 Here's the dput of z and also the column of n's I'd like to insert. Thank you in advance. z <- structure(list(24.1666666666667, 25.5, 26.3333333333333, 8.31027111835746, 9.4339811320566, 9.13866245766587, 54.3333333333333, 65.25, 63.1666666666667, 11.0068848977136, 16.3157759685081, 12.5323822978956), .Dim = 3:4, .Dimnames = list( NULL, c("term", "term", "term", "term")), rowLabels = structure(c("1", "2", "3"), .Dim = c(3L, 1L), .Dimnames = list(NULL, "approach"), justification = structure(c(NA_character_, NA_character_, NA_character_), .Dim = c(3L, 1L)), colnamejust = NA_character_, justify = NA, suppress = 0), colLabels = structure(c("pre", "mean", NA, "sd", "post", "mean", NA, "sd"), .Dim = c(2L, 4L), justification = structure(c(NA_character_, NA_character_, NA_character_, NA_character_, NA_character_, NA_character_, NA_character_, NA_character_), .Dim = c(2L, 4L)), colnamejust = character(0), justify = NA, suppress = 0), table = value * v * approach ~ variable2 * result_variable, formats = structure(c(NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA), .Dim = 3:4, .Dimnames = list( NULL, c("format", "format", "format", "format"))), justification = structure(c(NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA), .Dim = 3:4, .Dimnames = list( NULL, c("justification", "justification", "justification", "justification"))), class = "tabular") structure(c(12L, 12L, 12L), .Names = c("1", "2", "3"))
I'd like to actually understand the structure of this for future needs.
