  <li><p>I used function  ecmAsyFit(), from the from package "<a href="http://cran.r-project.org/web/packages/apt/apt.pdf" rel="nofollow">apt</a>":</p>
  
  <p><code>ecmAsyFit(gdp, life, lag = 1, split = TRUE,model = "linear", thresh = 0)</code></p></li>

  <p><strong>Problem:</strong></p>
  
  <ol>
  <li><p>After running the function, I got following result:</p>
  
  <p><code>Error in ecmAsyFit(gdp, life, lag = 1, split = TRUE, model = "linear",  : 
  Please provide time series data.</code></p></li>
