title: Plot a graph with all row names and column names
body: <p>I have a data frame with 5 column names and 10 row names. Values in this data frame consist of numbers between -1 to 1 and NAs. </p>

  <p>I want to plot a graph, where I have all rows with row names at Y-Axis and columns with column names at X-Axis. Also, values denote points of certain color and the shade of this color determines value being closer to 1 or -1. NAs can be a cross mark or can be ignored.</p>
  
  <p>Thanks in advance!</p>
