R help - Apr 2012 - Error while generating latex table from sweave and R?

Hi , 

I am generating one table without using latex. 

for (i in 1:LCol3) {

df <- data.frame(matrix(ncol = 6, nrow = 0))
datavec<-c(formatfile[formatfile[,3]==Col3[i],-3])
df<-rbind(df,datavec)
cat(Col3[i],"\n")
cat("\\begin{table}","\n")
cat("\\begin{tabular}{|l|l|l|}","\n")
        cat("\\hline","\n")
        #cat (line[1])
        for (i in 1:nrow(df)){
   for (j in 1:ncol(df)){
   cat ("&", paste(df[i,j]), " ")
   }
  cat("\\","\\","\n")
*  cat(paste (("\\"),("\\"),"\n"))*
}               
        cat("\\hline","\n")
        
    cat("\\end{tabular}","\n")
cat("\\end{table}","\n")
 #print(xtable(df,caption="Phenotype
Table",label="tab:summary",
align="lllllll"),include.rownames=FALSE,width=100)
}

In the above code, i need to add two backslashes "\\" at the end of
each
table record but if i use cat("///"), i m gettting error message. If i
use
cat("//","//") the backslahes are one space apart . How can
i solve my pblm?

Regards
