Hi R-fans, I would like put out a question to all R users on this list and hope it will create some feedback and discussion. 1) What are your 3 most useful R package? and 2) What R package do you still miss and why do you think it would make a useful addition? Pulling answers together for these questions will serve as a guide for new users and help people who just want to get a hint where to

...rix. Perhaps the xgboost package only imports certain functions from pkg:Matrix and that colSums is not one of them. This resembles the errors I get when I try to use grip package functions on ggplot2 objects. Since ggplot2 is built on top of grid I always am surprised when this happens and after a headslap and explicitly loading pfk:grid I continue on my stumbling way. library(Matrix) colSums(train$data) # no error > Note that as.matrix(M) can "blow up" your R, when the matrix M > is really large and sparse such that its dense version does not > even fit in your computer...

A stupid question but does anyone know how to express the actual colours used by the main Canadian political parties? I want to do a couple of ggplot2 plots and have lines or rectangles that accurately reflect the party colours. I can probably play around with RColorBrewer or something to figure it out but if some some already has got them it would save me some time especially with the NDP

Thank you for your responses. I guess I don't feel alone. I don't find the documentation go into any detail. I also find it surprising that, > object.size(train$data) 1730904 bytes > object.size(as.matrix(train$data)) 6575016 bytes the dgCMatrix actually takes less memory, though it *looks* like the opposite.
