title: How to save data file into .RData?
body: <p>I want to save data into an <code>.RData</code> file.</p>
  
  <p>For instance, I'd like to save into <code>1.RData</code> with two csv files and some information.</p>
  
  <p>Here, <strong>I have two csv files</strong> </p>
  
  <pre><code>1) file_1.csv contains object city[[1]]
  2) file_2.csv contains object city[[2]]
  </code></pre>
  
  <p>and additionally save other values, country and population as follows.
  So, I guess I need to make objects 'city' from two csv files first of all.</p>
  
  <p>The structure of 1.RData may looks like this:</p>
  
  <pre><code>&gt; data = load("1.RData")
  
  &gt; data
  [1] "city"  "country"  "population"
  
  &gt; city
    [[1]]               
    NEW YORK         1.1
    SAN FRANCISCO    3.1
  
    [[2]]
    TEXAS            1.3
    SEATTLE          1.4
  
  &gt; class(city)
    [1] "list"
  
  &gt; country
    [1] "east"  "west"  "north"
  
  &gt; class(country)
    [1] "character"
  
  &gt; population
    [1] 10  11  13  14   
  
  &gt; class(population)
    [1] "integer"
  </code></pre>
  
  <p><code>file_1.csv</code> and <code>file_2.csv</code> have bunch of rows and columns.</p>
  
  <p>How can I create this type of RData with csv files and values?</p>
