title: Avoiding for loop, Naming Example
body: <p>I would like to avoid using for loop in following example. Goal is to repeat string vector multiple times with different second part which changes each repetition. Is that possible?</p>
  
  <pre><code>str2D = mtcars 
  Vector = c(10,20)
  
  Dimen = dim( str2D )
  nn = c()
    for ( i in Dimen[2]*(1:length(Vector)) ){
      nn[ (i+1-Dimen[2]): i ] = rep(paste("|d",Vector[i/Dimen[2]],sep=""), Dimen[2] )
    }
  
  Name = paste( rep(names(str2D) , length(Vector) ),nn,sep="")
  </code></pre>
  
  <p>Correct result for "Name" vector is following:
  "mpg|d10"  "cyl|d10"  "disp|d10" "hp|d10"   "drat|d10" "wt|d10"   "qsec|d10" "vs|d10"   "am|d10"   "gear|d10" "carb|d10" "mpg|d20"  "cyl|d20"  "disp|d20" "hp|d20"  "drat|d20" "wt|d20"   "qsec|d20" "vs|d20"   "am|d20"   "gear|d20" "carb|d20"</p>
  
  <p>Thank you</p>
