a bit embarrassed about Excel & SPSS

I've been resisting R for years, but now that I have shed my mortal fear of learning any new syntax (e.g., MATLAB) I am loving it.  I'm also embarrassed that I relied on a crude combination of SPSS and Excel for plotting for so long.  I remain unapologetic though in my limited knowledge of MATLAB functions. Essentially, my capability with MATLAB is limited to typing the words 'SPM FMRI' at the prompt.
