[R] Printing a matrix in latexVerbatim without rownames.

[Duncan Mackay]

The original has not reached me yet

latexVerbatim is in Hmisc and appears similar to xtable::xtable

using xtable

library(xtable)

x <- matrix(rnorm(25), 5,5,dimnames=list(c(1:5),LETTERS[1:5]))
x

fhtml <- "latex.tex"
file.create(fhtml)
    
# open to append
ff <- file(fhtml, "a+")

writeLines(print(
xtable(x ),
       type    = "latex",
       tabular.environment = "tabular",
       include.rownames = FALSE,
       include.colnames = FALSE,
       only.contents = TRUE, 
       hline.after = NULL
), ff)

close(ff)

see ?xtable for formatting + more to suit your requirements

also have a look at dcolumn in latex

>From David Carlisle creator of dcolumn
\makeatletter
\newcolumntype{Y}[4]{>{\color{#1}\DC@{#2}{#3}{#4}}c<{\DC at end}}
\makeatother

and for the column specification

Y{black}..{-1} 

which takes a variable decimal format  rather than a fixed dcolumn one

You should post dput(x)

That is how R prints matrix objects. Perhaps you could convert to a
dataframe and suppress rownames. But knowing whether that is effective would
be facilitated by following the advice to post a reproducible example.
