 ==========================================================
 [![](http://www.r-pkg.org/badges/version/emil)](http://cran.rstudio.com/web/packages/emil/index.html)
-[![CRAN RStudio mirror downloads](http://cranlogs.r-pkg.org/badges/emil)](http://cran.r-project.org/web/packages/emil/index.html)
 
 The `emil` package for R is a toolbox for designing and evaluating predictive models with resampling methods.
 The aim is to provide a simple and efficient general framework
