I have a problem with running the tree package (dec.8, 2001) for R. The problem is, it will only give me 5/6 terminal node and then stop, while using Splus's tree on the same data with the same specification give me hundreds of nodes. Here's a little more background info: R-1.4.1 Solaris 5.7 rpart (most recent version) tree (..) Splus 6.0 Solaris 5.7 tree

Hi, Suppose I have the following lines at the end of a function: answer <- c(2, 1, 0, 4, 5) # In fact, answer will be generate in my # function print(answer) # Print the answer # Now, find the best fitted n degree polynomial print(paste("The best fit is with", which.min(answer) - 1, "-degree polynomial")) this will return:

Hi all, I am currently using the code snippet below to minimize a function which I wasn't able to minimize properly with optim (cliffy surface, constraints, poles). Obviously this iteration is probably the poorest way of implementing such a function and it is expectedly slow. I've already written some vectorized functions, but I'm afraid that I'm missing the "big

Hi all In two days, I am giving a small, informal workshop in our Department about using R. Initially, it was just for statistician, but surprisingly (to me anyhow) many mathematicians are also coming who have a MATLAB background. They are coming at the Workshop from a teaching perspective. They are considering using R to avoid licensing issues with MATLAB. One thing they were hoping me to

Hi All, I am having trouble installing the sm package, and only the sm package. My box is RedHat 7.3 on a PIV. Readline 4.3-3 is installed (suited for RH 8, but same error under readline 4.2 for RH 7.3), but it seems to be looking for the readline library in the wrong directory. Will installing readline 4.1 do the trick? What else could be done? Rohan Sadler [root at rsadler R]# R CMD

Hello, Although your message is not very explicit about the structure of your data frame, I think you can get what you want by using a combination of the function "split" and the "apply" functions family: apply, lapply and sapply. If you provide a more detailed organization of your data frame, perhaps we can give to you a more wiser advice. Thanks, Carlos. P.S: By the way,
