Hi all, I would like to do cross validation in random forest using rfcv function. As the documentation for this package says: rfcv(trainx, trainy, cv.fold=5, scale="log", step=0.5, mtry=function(p) max(1, floor(sqrt(p))), recursive=FALSE, ...) however I don't know how to build trianx and trainy for my data set, and I could not understand the way trainx is built in the package

Hi, i have some problems with xen-3.0.1 and the network-bridge script. After ''/etc/init.d/xend start'' or ''/etc/xen/script/network-bridge start'' everything works perfect (as well as the domU''s network) - but only for a few seconds (~20s). After that the network seems to crash - no outgoing or incoming connection possible. I have read a forum

I have a local library which depends on the expm library. The expm library is loaded into my personal space and I have the environment variable R_LIBS_USER set appropriately. The command "library(expm)" works just fine from the command line, and in fact the package works if I do the source() and dyn.load() commands by hand. The following sequence works: tmt% R CMD build

I tried to cross-compile the newest release 2.0.1 on a linux machine, but i always got an error at the following stage DHAVE_CONFIG_H -DR_DLL_BUILD -c dynload.c -o dynload.o dynload.c: In function `R_loadLibrary': dynload.c:94: warning: implicit declaration of function `_controlfp' dynload.c:94: error: `_MCW_IC' undeclared (first use in this function) dynload.c:94: error: (Each

Dear all, Does anyone have any idea on how to speed up the for() loop below. Currently it takes approximately 2 minutes and 30 seconds. Because of the size of Nsim and N, simulating a multivariate normal (instead of simulating Nsim times a vector of N normal distributions) would require too much memory space. Many thanks for your kind help, Simona N=3000 PD=runif(N,0,1) cutoff.=qnorm(PD)

Hi, perhaps the answer to my question is obvious and I didn?t find it because I?m new to R ... The problem is as follows: I read some data from file, do some commands which are well processed and finally make some graphics. OK Then I put these commands together in a *.R file which I can process ... Among these i. e. is sum_input = summary(mydatatable) sum_input ..... plot(mydatatable) What

Martin, I am aware of --vanilla; I use it myself for some testing. In this case R_LIBS_USER was set externally (part of my login) and does not involve any of the R scripts. That means it is inherited by any subprocess. For example: tmt1495% R --vanilla --no-environ R version 3.3.1 (2016-06-21) -- "Bug in Your Hair" Copyright (C) 2016 The R Foundation for Statistical Computing

Our CEO, Dr. Dan Steinberg, is planning to visit Europe in May. He would like the opportunity to introduce statisticians (and statistically minded people) to data mining, data mining applications and to forefront data mining tools. Our algorithms are probably familiar to many statisticians (CART, MARS, MART, TreeNet and RandomForests), although it isn't necessary to be a statistician to

Martyn, No, that didn't work. One other thing in the mix (which I don't think is the issue) is that I call one of the C-entry points of expm. So the DESCRIPTION file imports expm, the NAMESPACE file imports expm, and the init.c file is #include "R.h" #include "R_ext/Rdynload.h" /* Interface to expm package. */ typedef enum {Ward_2, Ward_1, Ward_buggy_octave}

Hi All I have just upgraded from to Samba 2.0.0 from 1.9.18p8. Everything seems cool except my macintosh clients (running Dave v2.0 and v2.1) are not now able to access anything from the samba shares. The samba server still appears in chooser and you can select any share and mount it, but there appears to be nothing in it and you cannot copy anything to it. My other netbios machines on the

Hi, Plenty to talk about today. Dave Nelsen, a founder of Talkshoe, has a lot of experience in the telecommunications space and he joins us today to chat about its current state, conferencing and whatever else comes to mind. So we have a meta conference aout conferencing, it won't be the first time :) You probably saw John Todd's message on one of the lists: Skype for Asterisk is in open

I'm running stock RH9, which has the samba-2.2.7a-8.9.0 RPM installed on it. My friend has a Mac running OSX and the "DAVE" file sharing software. I can mount his shared folder using the following command: smbmount //tritanium/graphics /mnt/tritanium ...and I can see all the files in that folder when I do "ls /mnt/tritanium." But...
