I have the data: for x: 2, 8, 14, 20, 26, 32, 38, 44, 50, 56, 62, 68, 74, for y: 100, 99, 99, 98, 97, 94, 82, 66, 48, 38, 22, 10, 1. y depends on x by equation: y = 100*exp(b*(1-exp(c*x))/c), where b and c are coefficients. I need to find coefficients in this equation for given data. How can I do that by means of R? Thank you for advance. With regard, Dmitry.

Hi, I am a student studying Biostatistics at University. We have been advised to install R and R commander. I managed to do this successfully, except I wasn't able to complete the final step - which would enable both R and R commander to launch when I open the R icon on my desktop. However, I haven't been able to save it and for this to work. The last instructions we were given are:

Dear all, ggplot currently requires 13 packages (grid, reshape, RColorBrewer, proto, splines, MASS, Hmisc, boot, butler, hexbin, mapproj, quantreg, sm). Some of these are absolutely necessary (eg. proto), but most are used for one or two specific tasks (eg. boot is only used to get plogis, used for logit scales).
