  The 'mosaic' package masks several functions from core packages in order to add 
  additional features.  The original behavior of these functions should not be affected by this.
  
  Note: If you use the Matrix package, be sure to load it BEFORE loading mosaic.
  
  In accordance with CRAN policy, the 'mdsr' package 
             no longer attaches
  the 'tidyverse' package automatically.
  You may need to 'library(tidyverse)' in order to 
             use certain functions.
