similar to: Installation of R on UNIX - Sparc Solaris v8 [SEC=UNCLASSIFIED]

Dear All, I am currently using R in Windows PC with a 2 GB of RAM. Some pretty large datasets are expected soon, perhaps in an order of several GB. I am facing a similar situation like Ralph, either to get a new PC with a bigger RAM or else. I am just wondering if R is getting faster in other systems like UNIX or Linux. Any suggestions are appreciated. Regards, Jin

Hi All, I installed R 2.5.1 recently on a PC (Windows XP Professional 2001) and tried to install some R packages. It took several minutes and gave me the following message. > utils:::menuInstallPkgs() --- Please select a CRAN mirror for use in this session --- Error in open.connection(file, "r") : unable to open connection In addition: Warning message: unable to connect to

Dear R-Users, as I will start a huge simulation in a few weeks, I am about to buy a new and fast PC. I have noticed, that the RAM has been the limiting factor in many of my calculations up to now (I had 2 GB in my "old" system, but Windows still used quite a lot of virtual memory), hence my new computer will have 4 GB of fast DDR2-800 RAM. However, I know that 1.) Windows 32 bit cannot

Hi all, I used the following code and data to get auc values for two sets of predictions: library(caret) > table(predicted1, trainy) trainy hard soft 1 27 0 2 11 99 > aucRoc(roc(predicted1, trainy)) [1] 0.5 > table(predicted2, trainy) trainy hard soft 1 27 2 2 11 97 > aucRoc(roc(predicted2, trainy)) [1] 0.8451621 predicted1: 1 1 2

Hi all, I would like create a new column in a data.frame (a1) to store 0, 1 data converted from a factor as below. a1$h2<-NULL for (i in 1:dim(a1)[1]) { if (a1$h1[i]=="H") a1$h2[i]<-1 else a1$h2[i]<-0 } My question: is it possible to remove the loop from above code to achieve the desired result? Thanks in advance, Jin Geoscience Australia Disclaimer: This e-mail

Hi Tobias, Here is something I acquired from this mailing list some years ago. It works well for me: #---run in previous version (e.g. R 3.1.0) packages <- installed.packages()[,"Package"] save(packages, file="Rpackages_R3.1.0") #---run in new version load("Rpackages_R3.1.0") for (p in setdiff(packages, installed.packages()[,"Package"]))

Hi All, Just thought you might be interested in a recently released R package, spm: Spatial Predictive Modelling. It aims to introduce some novel, accurate, hybrid geostatistical and machine learning methods for spatial predictive modelling. Of 22 functions available in spm, two functions are for accuracy assessment. Perhaps they are not only useful tools for spatial predictive modelling

Hi All, I tried to use xgboost to model and predict count data. The predictions are however not as expected as shown below. # sponge count data in library(spm) library(spm) data(sponge) data(sponge.grid) names(sponge) [1] "easting" "northing" "sponge" "tpi3" "var7" "entro7" "bs34" "bs11"

Dear R users, A new version (1.1.0) of the ?spm? package for spatial predictive modelling is now available on CRAN. The introductory vignette is available here: https://cran.rstudio.com/web/packages/spm/vignettes/spm.html There are several new enhancements to the package including a fast version of random forest in using ranger (rg) library(ranger) and the ability to convert relevant

Samba 3.3.3 I've seen some relevant posts, but no answers. Users on XP32 boxes will see duplicating directories inside of each other when accessing a samba share through dfs. Not sure how to recreate, but it happens regularly. Problem does not occur when accessing share directly. Performance does not seem affected. A reboot of XP will resolve the issue. Thanks. djm

Davood, I developed an MC simulation model for wind hazard analysis last year. I found three important issues to increase efficiency: 1) Reuse most variables in each loop 2) Write results (1000 stats) to external files, perhaps one file for each condition. (a good ID for each file can be implemented using "paste") 3) Develop a function to process the results stored in the external

Hi, I would like to create a matrix. Say 5*4. The first column is integer, the second column is date, the third column is character and the rest columns are integers. So it's a combination of different types. I am wondering how can I do that? "matrix" command only allow one type. ********************************************************************************* This e-mail message

Hello Recently I've been happily experimenting with syslinux, replacing grub and my old bootmanager. All works beautifully, but I have one question - in case of .bss bootsectors - what exactly and under what circumstances is patched in ? With syslinux used as main bootmanager - bootsectors from xp64, xp32 and [pre-syslinux] msdos 7.1 (98se) work perfectly fine when chainloaded natively as

I'm using a Proliant GL-380 server running Red Had Linux ES 4 (2.6.9-5.0.3.ELSMP) and Samba 3.0.10-1.4E. The server is acting as a Domain Member Server of an ADS Windows 2003 server. The problem I haveI been having is with some groups not being "migrated" to the Linux environment, or more specifically converting the group SIDs to GIDs. The problem can be summarised as follows: *

I have the following problem, and I would l like to know if Samba can help. (I suspect that it cannot, but feel free to prove me wrong.) My scenario is this: My site is just one of many, with the `Domain Master Browser` being off-site. My site has 10 VLANS, and in the current, purely Windows environment I have assorted problems with the browser list being maintained across all 10 VLANS. I would

Hi all, When upgrading to 2.11.1 recently I noticed different results being produced by my code. After much digging I have finally narrowed it to a call to nlm(). This can be replicated by: FixedRemovals<-1836180125888 AbStageInitial<-2223033830403 Rates<- 0.3102445 nlm(function(rootM,Abund,Loss,OtherM) {(Loss-(rootM/(rootM+OtherM)* (1-exp(-(rootM+OtherM)))*

Hi, You can exit out of the 'identify()' routine by either: right-click > 'stop' Or click on 'stop > stop locator' in the top-left of the plot window.
