Thanks, Gerrit.Hi Gerrit, I haven't used latex.table from quantreg so I can't comment on this approach. However, I would recommend using the xtable package to format your data.frame into LaTeX: require( xtable ) x<-data.frame(Name=c("Jan","Piet","Jan"), V=c(1,2.991,3)) # Create a table object from the data.frame latexTable <- xtable( x ) # Set the number of digits in each column. Your example has two columns, # but we must specify three digits since the rownames count as a column. digits( latexTable ) <- c( 0, 0, 2 ) # Print the table object in order to produce the LaTeX code. print( latexTable ) You should also read the help page for print.xtable() as it discusses many options that can affect the final LaTeX output. Hope this helps! -Charlie
