I was wondering if anyone had any tips or tricks that may make this run faster? Below is

Merry Xmas to all, I am writing a function and curiously this runs sometimes on one data set and fails on another and i cannot figure out why. Any help much appreciated. If i run the code below with data <- iris[ ,1:4] The code runs fine, but if i run on a large dataset i get the following error (showing data structures as matrix is large) > str(cluster.data) num [1:9985, 1:811] 0 0 0 0

Hi all, I got this time for my code, > proc.time()-pt user system elapsed 132541.743 0.004 132533.526 As you can see, there is huge difference btw elapsed time and system time. Does that mean lots of I/O? Or some bad coding? Thanks, Libo [[alternative HTML version deleted]]

Hi, I'm working in R 2.11.1 x64 on Windows x86_64-pc-mingw32. I'm experiencing a strange problem in R that I'm not even sure how to begin to fix. I've got a huge (forty-pages printed) simulation written in R that I'd like to run multiple times. When I open up R and run it on its own, it works fine. At the beginning of the program, there's a variable X that I set to 1,

Hi everybody, this is a real dummy thing. I sorted a matrix based on a given column, and what I get is right, until it comes to columns of negative and positive values; than, "order" orders everything from max to min in the negative values, and then AGAIN from max to min in the positive values!!! Why isn't everything order from max to min, and that's it? Thank you!!! Attached

Dear all I'd like to give RExcel a decent spin, mainly to take advantage of Excel's data management facilities and automatic recalculations. However I cannot use this Windows-only solution on the platform of my choice, Linux. Alternatively I've been considering the cross-platform ROOo, the OpenOffice equivalent of RExcel, but in this case the problem is that the only release available

Dear all: I¡¯m trying to get unbiased feature importance of my data via package ¡°party¡±, which contains 1-5 integer value, and a few numeric values attributes. The class label is 1-5 integer value as well. In total I have 20 features with 1100 observations. I checked the type my data in R using class(my_data_cell), no factor has been observed. I received a commond error like others did
