I am trying to find the difference between rows using the diff() function. However, because the rows contain NaN values I am getting the following error.
'Check for missing argument or incorrect arugument data type in call to function diff'
The data is a timetable with weekly closing stock prices and I just need to calculate the difference in price between weeks.

You can substitute all 'nan' values with 0's by locating them via isnan() and then substituting.
