Creating a bigger data frame by joining multiple data frames : <p>I currently have multiple data frames (named cont, cont2 .... cont7), and need to combine them</p>

<p>Each data frame has 2 columns; date and a mean temperature value (taken from a netcdf file)</p>

<p>The dates are monthly values, in 
cont = 1951-1 to 1960-12 
cont7 = 2011-1 to 2014-12
(basically monthly values split into groups of 10 years, from Jan 1951- Dec 2014)</p>

<p>How can I extent my data frame so all values are in 1 table? I want to make it continuous so as to plot a time series</p>
