Hi, I've completely forgotten how to do R, and it seems I can't even load simple files correctly. I have two tab deliminated text files (attached, these were test files of the larger data files I'm trying to work with) that I am trying to load into R so that I can merge them. They were originally excel files but I used "saved as" to reformat to text. I don't know if

Hello r-help, I'm trying to split a character vector of dates of the form "dd-mmm-yy" into component days, months and years. But > library(chron) > testdate<-as.POSIXlt(strptime("17-Sep-98","%d-%b-%y")) > testdate [1] "1998-09-17" > months(testdate) [1] "September" # which is fine, but for days and years I get >

Hi everyone, I am not new to R, but its been over a year since I've used it, so I don't remember how to do some things. I have a data set (in excel currently, but will be converted to text), that has date, country and price, with a price for every country for every date. I need to find the mean and median of the interval between price changes for each country and the mean and median

While playing with DB function in Dialplan, I have added some garbage in AstDB. These are some family names with space in them. See this, demo*CLI> database show /18-05-2011 00:00:0052011175221575/TESTDATE : 2011-05-14 21:33:46 /18-05-2011 00:00:0052011175221575/TEST1 : 410 /18-05-2011 00:00:0052011175221575/TEST2 : 155 /18-05-2011 00:00:0052011182614252/TEST3 :

With dates I get different results with 2.2.1 and 2.3.1. From my somewhat naive point point of view, the 2.2.1 behaviour seems more sensible. Running the code below in 2.2.1: V1 2006-08-01 2006-08-01 1 1 With 2.3.1 I get: V1 1154354400 1154440800 1 1 # testdate.R t <- read.csv2('testdate.csv', header=FALSE) t$V1 <- as.POSIXct(t$V1)

Hi, I am trying to build a VERY basic neural network as a practice before hopefully increasing my scope. To do so, I have been using package "neural" and the MLP related functions (mlp and mlptrain) within that package. So far, I have created a basic network, but I have been unable to change the default activation function. If someone has a suggestion, please advise. The goal of the

UseRs, I am working on a dataset (see small example below) where individuals were followed on a specific date-time combo and multiple repeated measurements were taken (e.g., height in meters, behavior class in 2 letter code). Observation numbers varied between individual (ranging from 1 observation for each date-time combo to >50) I am trying to summarize the data into 1 row per

Hi everyone, A few days back Jim helped with out, helping me find an automated way of determining the mean and median of intervals between price changes. However, a new set of data I have is no longer in the same format. CDSmod is the file that was used with this code: x <- read.csv('/cdsmod.csv', as.is=TRUE, check.names=FALSE) x$Date <- as.Date(x$Date, "%m/%d/%Y")

Dear R users: I have a problem about catch the value from function. I have following two functions (part): fbolus1 <- function() {......... par<-data.frame(Parameter=c("kel","Vd"),Initial=c(0)) check(par) .....} check<-function(par) { if (par[ ,2] <= 0){ cat("\nEnter again (y/n) ?\n\n") ans<-readline() if (ans == "n" ){

Hi, I have a time series problem that I would like some help with if you have the time.

Hi, wbinfo -Y BUILTIN\group can work without idmap_rid in Samba-3.0.14a. But I'm experiencing wbinfo -Y with idmap_rid failed for SID to GID conversion of BUILTIN groups. Since idmap_rid only works in a single domain, and captures workgroup's domain sid as a real domain sid in rid_idmap_get_domains(), when running "wbinfo -Y BUILTIN/System Operators", the function

Dear list, I am an R user and I also write my own package in R(sometime i need to write in C), and right now i am thinking about buying a new workstation--and i am trying to decide if i should get a mac with OS X or a linux machine (for example Dell). I have experience using R on linux (but i have been just a user and never been a admin) but i am hesitating of managing a linux system on my

Hello everybody, I have been recently using reshape to convert "long" data to "wide" data. Everything was going well until I reached some problematic datasets. It has taken me a couple of weeks to finally figure out what might be happening. The problem is reproducible with test cases, and on two versions of R (Windows 2.2.0 and x86-64 Fedora Core 3 R 2.2.0). The data

Dear all, I tried to use "step" function to do model selection, but I got an error massage. What I don't understand is that data as data.frame worked well for my other programs, how come I cannot make it run this time. Could you please tell me how I can fix it? ***************************************************************************************************

Dear all, I wrote a function test1 in test1.R. Right, I am writing another function test2 on test2.R and trying to use test1 function. How can I do? Is there any similar way like including test1.R in test2.R file? Thank You Very Much.
