Alan, I can't answer your first question, but as far as the second question goes, have you examined RStudio? http://www.rstudio.com/ Rstudio is a free, nice, IDE (I think this stands for integrated development environment that facilitates working in R. I provides very very basic sytax help (i.e. makes sure parenthesis are balanced), but more importantly allows for viewing plots generated by code more easily. John

I have a particular interest in generalised linear models (GLMs) and I'm experienced in fitting them using other bits of software. R can fit GLMs of course, using the glm() command. I have some large multivariate data sets I'd like to fit GLMs to, ideally using R. Two concerns though: Firstly, I'm told that R isn't especially fast at fitting GLMs, especially if the data files are too large to fit into RAM. Can anyone advise if there are alternatives to glm() around which might cope better. For example, I've heard that RevolutionR is available, and claims to fit GLMs faster in these cases. Might it be possible, alternatively, to write some very quick code using C (for example) and to get R to invoke this instead? Has anyone tried to do this? Secondly, I might like to create some kind of GUI so that I can have a nice interface for viewing data, specifying models, showing graphical model outputs, etc. Is there a preferred way to do this? The only GUI builder I know of is Shiny - http://www.rstudio.com/shiny/ - is this a good way to go? What alternatives might I consider? My IT/coding skills are limited. I'm hoping at some point to find an R expert to collaborate with, but in the mean time, a few pointers would be appreciated. Thanks!
