R: Creating Latex tables without environment code
How can I print latex-formatted tables (eg summary statistics, no regression output) in R, but without the environment code like begin{table}[!htbp] centering ?
I tried many packages listed in Tools for making latex tables in R. Only the stargazer package seems to have an option for suppressing Latex environment code, namely out.header=FALSE . But that option seems to have no effect. Other packages seem to haven even less options.
Background: I have two table of very similar kind (spearman and pearson correlation, in my very case) which I would like to have in one table in Latex. I think of simply calling the R generated, latex-formatted output in a third latex file, which is ultimately called in the Latex document. But if there are other possibilities to create two R generated Latex-style tables in one .tex document, I'd be glad to use them.
You can do this with xtable :
Here's default behavior:
> print(xtable(table(1:5)))
% latex table generated in R 3.1.1 by xtable 1.7-4 package
% Sat Nov 08 14:57:56 2014
begin{table}[ht]
centering
begin{tabular}{rr}
hline
& V1
hline
1 & 1
2 & 1
3 & 1
4 & 1
5 & 1
hline
end{tabular}
end{table}
If you include floating = FALSE in the print method options, you can get your desired result:
> print(xtable(table(1:5)), floating = FALSE)
% latex table generated in R 3.1.1 by xtable 1.7-4 package
% Sat Nov 08 14:57:51 2014
begin{tabular}{rr}
hline
& V1
hline
1 & 1
2 & 1
3 & 1
4 & 1
5 & 1
hline
end{tabular}
There's very fine-grained control here, but most of the options are described in ? print.xtable ? print.xtable , not ? xtable ? xtable .
Why don't you merge the two tables into one data.frame in a first step, and then format the combined thing for your task? There are only few details in your question but I imagine something along these lines here could work:
x <- rbind( cor(mtcars, use="complete.obs", method="spearman"),
cor(mtcars, use="complete.obs", method="pearson" ))
rownames( x )[12:22] <- paste( rownames( x )[12:22], "a", sep = "-" )
xLatex <- xtable( x )
