Creating a latex table from ftable object in R

Question

Let me create some data before I ask my question.

 my.data <- data.frame(A = sample(seq(1,100,by=5),10,replace=TRUE),W = rnorm(10),X =sample(1:10),Y = sample(         


        

Answer 1

Building off of user2030503's answer,

# install.packages('simsalapar')
library(simsalapar)
utils::toLatex(result1)

The function toLatex is an S3 generic so passes to simsalapar:::toLatex.ftable() when given an ftable object. Alternatively you can just do simsalapar:::toLatex.ftable(result1).

Once that was done I needed to include \usepackage{booktabs} in the latex preamble as toLatex.ftable uses \toprule. Alternatively you can pass booktabs=FALSE.

It also looks like toLatex.ftable trims out trailing zeroes. To fix that this is what I did (see the answer to Formatting Decimal places in R for format()):

result1[1:nrow(result1),1:ncol(result1)] %<>% as.numeric %>% format(nsmall=2,digits=3)

this converts the matrix of the ftable to a character matrix, but toLatex.ftable still works.

I also found it helpful to \usepackage{pdflscape} and wrap my table with \begin{landscape} and \end{landscape} because these contingency tables can be quite wide.

Answer 2

Use the toLatex() function provided by the simsalapar Package.

library(simsalapar)
toLatex(result1)

Answer 3

Method 1:

require(MIfuns)
require(Hmisc)
latex(ftable2data.frame(result1))

Answer 4

As an alternative, memisc provides toLatex methods for ftable objects.

library(memisc)
toLatex(result1)

Answer 5

You can use the package xtable:

library(xtable)
mytable=ftable(mydata)
print(
  xtable(format(mytable)),file="~/Desktop/mytable.tex"
)

I don't know how it compares to the other options given.
