Hi I know this only affects a small number of subscribers, so I apologize to the "Non Stellenbosch University subscribers" for the noise. Two weeks ago, four R users met and discussed the possibility of forming an interest group of R users at SUN. The interest group (R at SUN) has the aim of: ? Promote the use of R at SUN (Stellenbosch University); ? Organize Hons stats courses using R; ?...

Hi R experts :) I'm trying to carry out a survival model on my data, but I am unsure of whether it's appropriate or if I should do something specific in regards to hazard. My data is time to death by predator where I have 8 prey and one predator in the setting. This means that two prey can't possibly die at the same time and I can't quite get my head around how to include this in

Hi, I would like to find out the coordinates of the intersection points of 2 density curves. I did a search but i didn't get any significant results. I really hope some of you have some ideas. here it is an example: set.seed(123) x1 <- rnorm(100, 1, 1) x2 <- rnorm(100, 0, 1) d1 <- density(x1) d2 <- density(x2) plot(d1, col = 2) lines(d2, col = 4) Now i would like to know

...linear. Also would like to add A^2 and B^2 into the ANOVA and modeling. Please can you help with regard and offer some advice. Your help is much appreciated.
