Dear list, I'm trying to download a text file directly from the internet using the RCurl package and the command getURL. Duncan Lang graciously helped me solve the first step in this problem using the following command: ################# txtfile <- getURL('ftp://ftp.wcc.nrcs.usda.gov/data/snow/snow_course/table/history/idaho/13e19.txt', ftp.use.epsv = FALSE) #################

Dear list, After searching many old posts, I can't find the solution to a simple problem. can someone tell me how to create a character string with multiple backslashes, as in: file_dir <- c("C:\files\data\") I need to create this string and then paste it to many files names for batch processing in another software program.

Dear list, I'm trying to write my first looping function in R. After many hours of searching help files and previous posts, I'm at wits end. Please forgive my programming ignorance...any help is greatly appreciated. I need to sort through a vector (x) and identify the point at which 2 successive values become smaller than the previous value. I've written a "while"

Dear List, I'm stuck on what seems like a simple indexing problem, I'd be very grateful to anyone willing to help me out. I queried a dataframe which returns a character vector called "plot". I have another dataframe from which I want to subset or select only those rows that match "plot". I've tried subset, and also the "which" command. plot

Greetings R list, I am stuck on a simple syntax problem. I want to list all files in a directory, excluding files of a certain type.

I have read the regexpr help files and search old posts to no

Dear list, I've recently installed R on a 64 bit machine with 8 GB of RAM. I set this computer up as a dual-boot system, with windows XP 64 and Ubuntu 7.10. I downloaded the Linux 64 bit version of R and installed it. I'm trying to run rather large Random forest models and was running into severe memory limitations with my old windows 32 bit machines. When I run Random Forest models

Hi guys, I can't see virtio in releng/9.1, is there any particular reason why it isn't going to be included given that it works reasonable well (and is optional anyway, so not likely to be detrimental)? Thanks, Joe

Hi all. I'm having a strange issue with a server running Samba 3.0.2a. The server has a single share, and under that are subfolders that contain documents. Each subfolder is owned by a different folder-specific group, and users belong to the groups that own the folders to which they need access. But suddenly one user can't access any folders. Windows (the client) suggests that she

See: http://syslinux.zytor.com/archives/2006-May/006887.html I think I've tracked the problem down a bit more specifically. In edd.S when the kernel calls int 0x13 with %dl=80 [primary disk] & %al=1 [read one sector] and ah set to READ_SECTORS it never returns. However, the following code [which does drive diagnostics] works. mov $0x7E, %al call prtchr movw $0x0000, %ax movb

Hi, I am a newbie of R, and playing with the "ifelse" statement. I have the following codes: ## first, for(i in 1:3) { for(j in 2:4) { cor.temp <- cor(iris.allnum[,i], iris.allnum[,j]) if(i==1 & j==2) corr.iris <- cor.temp else corr.iris <- c(corr.iris, cor.temp) } } this code is working fine. I also tried to perform the same thing in another way with "ifelse":

Dear list, I have a question I'm trying to use the following command in R, but it gives me an error message.The command is: data<-ddply(data,c("year","name"), transform, check1=ifelse(check1==1 & check2==1, 1,NULL)) so in my data frame I already have the check1 variable, if the conditions (check1==1 & check2==1) is respected, check has to have 1 as value,

I'm trying to find a good open source software to do sales forecasting using Holt Winters and Box Jenkins time series algorithm. Somebody pointed me that R is the best open source available for statistical computing. Are there functions to do Holt Winters and Box Jenkins time series prediction in R? If there is none, can some one point me a good GNU/freeware to do the sales forecasting using
