There is no file attached. If you're using R, consider using an .R script with comments (or better yet, a Rmd/Rnw with all the relevant data) and desired result. Make sure your example is reproducible. Cheers, Roman On Sun, Nov 16, 2014 at 11:04 AM, Chandrasekhar Rudrappa chandr...@gmail.com

You *can't* send docx files as attachments to this list; most attachments get stripped. Consider doing something useful with the content of the docx and put the content as plain text into an email and send that. HTH G On 16 November 2014 05:46, Chandrasekhar Rudrappa chandr...@gmail.com wrote:

Hi All, I have to fit the following model to growth data of Hevea (rubber) trees. [image: a = a - (a - b){e^{ - \,\,\frac{2}{T}(F(t) - F({t_0}))}}] where [image: F(t) = t + \frac{A}{{2\pi }}\sin 2\pi (t - {t_1})], [image: F({t_0}) = {t_0} + \frac{A}{{2\pi }}\sin 2\pi ({t_0} - {t_1})], and *t1*
