title: Excel VBA: Determine if range is horizontal or vertical
body: <p>I want to create a function that, among others, has a range as input.
  This range will be 1 row by ? columns or 1 columns by ? rows. In other words, it will be "one dimensional" - either horizontal or vertical.</p>
  
  <p>Based on whether it is H or V, certain calculations will be made.
  How can I determine if the range that is passed is horizontal or vertical?</p>
