title: Analysing a data frame that contains a time series using stargazer
body: <p>I have a <strong>panel data set</strong> of 10 obs. and 3 variables.
  (# of obs. 30 = 10 rows (= countries) * 2 columns  (= migration parameters) * 1col for the respective year.
  My data frame consists of 3 annual data frames, so to say.</p>
  
  <p>How can I apply <strong>stargazer</strong> on the whole period of time by taking into account that it is a panel data set (so max N=10)? That is, R should start over after every 11th row. I'd like to get the pretty table for descriptive statistics</p>
  
  <p>The data set for the first three years:</p>

  <p>I still get descriptive statistics from N=30, but it should N=10, since I'm looking for the descriptive statistics of the whole period of three years and each yearly data frame needs to be considered isolated for that.
  Hope I expressed the problem comprehensibly </p>
