Latex Tables and the `xtable' package

[AC3112]

Hi All,

I've recently been trying to generate some Latex formatted tables using the 'xtable' package in R.

However, the formatting of some of the columns is different from the original output.

A snapshot of my original output is given:

print(postClassProbs(trial.lca4), row.names = FALSE)
``
MR Mob SC Act Pain Anx Freq      Class 1      Class 2     Class 3
  0   0  0   0    0   0 2845 2.642918e-06 8.776227e-01 0.067042881
  0   0  0   0    0   1  911 4.391841e-07 9.293405e-01 0.030696931
  0   0  0   0    1   0  616 8.220266e-07 9.226063e-01 0.062474787
  0   0  0   0    1   1  683 1.072411e-07 9.719491e-01 0.020051938

However, when I run the xtable command, I get:

xtable(print(postClassProbs(trial.lca4), row.names = FALSE))

````\begin{table}[ht]
\centering
\begin{tabular}{rrrrrrrrrrrr}
  \hline
 & MR & Mob & SC & Act & Pain & Anx & Freq & Class 1 & Class 2 & Class 3 & Class 4 \\ 
  \hline
1 & 0.00 & 0.00 & 0.00 & 0.00 & 0.00 & 0.00 & 2845.00 & 0.00 & 0.88 & 0.07 & 0.06 \\ 
  2 & 0.00 & 0.00 & 0.00 & 0.00 & 0.00 & 1.00 & 911.00 & 0.00 & 0.93 & 0.03 & 0.04 \\ 
  3 & 0.00 & 0.00 & 0.00 & 0.00 & 1.00 & 0.00 & 616.00 & 0.00 & 0.92 & 0.06 & 0.01 \\

In other words, I'd like to ensure that zeroes and ones remain as single numbers, yet xtable changes the format.

Would anyone know how to amend this?

Any help appreciated

Self-answered:

You need to exploit the digits command:

xtable(postClassProbs(trial.lca4), row.names = FALSE, digits =c(0,0,0,0,0,0,0,0,4,4,4,4))
