title: Hmisc and LaTeX multicloumn
body: <p>I am trying to create a multicolumn in a LaTeX table. It's easy to do this manually but I create these tabled from data frames generated fro many reports so doing it manually is time consuming. What I have is :</p>
  
  <pre><code>cat(cfrm, file="table2.tex") # this categotises the file
  t2&lt;-latex(tabl2, file="table2.tex", cellTexCmds = cellTex, rowname=NULL, colheads=c(paste("Recent Average Catch (",minyear," - ",maxyear,")",sep=""), "Skipjack", "Yellowfin","Bigeye","SP Albacore"),  
            caption=paste("Key fishery statistics averaged from ",minyear," to C$_{latest}$ for each of the four main target tunas. Where C$_{latest}$ is the last year in each species assessment model. \\label{tab2}", sep=""), caption.lot=NULL, caption.loc='top', 
            longtable=TRUE, collabel.just=c("c","c","c","c","c"), size="small", 
            col.just=c("l","c","c","c","c"), colnamesTexCmd=c("apple") , append=TRUE)
  </code></pre>
  
  <p>which fives me the table attached:
