In 2014 Dice Tech Salary Survey of over 17,000 technology professionals, highest paid IT skill was R programming.
While big data skills in general featured strongly in the top tier, having R at the top of the list reflects the strong demand for skills to make sense of and extract value from big data.
Similarly, the recent O`Rielly Data Scientist survey also found R skills amongst those that pay in the $111,000 - $125,000 range.
