A real basic question on R I have a txt file and I am trying to read it into R but getting an error reading it in.I've set the path of R to where the folder is and then typed the following Santa <-read.table("IsThereASantaClaus.txt")but I get a whole host of errors Error in file(file, "rt") : cannot open the connectionIn addition: Warning message:In file(file, "rt") : cannot open file 'IsThereASantaClaus.txt': No such file or directoryI then tried puting the path direct > Santa <-read.table("C:\\Users\\Player\\IsThereASantaClaus.txt")and as > Santa <-read.table("C:\Users\Player\IsThereASantaClaus.txt")but still cant get it read.Can anyone help pleeeeease

try copying file to where your R is.

R uses unix forwardslashes in paths rather than windows backslashes, sosanta <-read.table("/users/player/isthereasantaclaus.txt")or santa <-read.table("c:/users/player/isthereasantaclaus.txt")should work

QuoteSanta <-read.table("IsThereASantaClaus.txt")you just typed in the name of your file.what about your working directory ?you may set your working directory :example : setwd("C:/Users/WilmottForumUser/desktop")you then can open you file :data<-read.table("IsThereASantaClaus.txt")but that very depends on the actual content of your file.in any case, you should specify the way your file is organized and what your data look like using the sep, dec, heade, na.strings keywords.that way you would be sure to open your file properly.édouard

thanks guys. Now working

For some reason when I run the following on a new PC > source("http://www.rmetrics.org/Rmetrics.R")> install.Rmetrics()I get the following error msg in file(file, "r", encoding = encoding) : unable to open connectionIn addition: Warning message:unable to resolve 'www.rmetrics.org'. in: file(file, "r", encoding = encoding)Any idea what is going wrong?It worked on my old PC last week

Do you have any kind of outgoing firewall? Zonealarm etc? Which Mirror are you using? Which OS? Which R version?

There is a firewall. The version is 2.5.1

I guess the issue is how do I change the intenet proxy to connect R to the web?

Set the proxy in IE and then start R with: "C:\Program Files\R\R-2.xx.0\bin\i386\Rgui.exe" --internet2 or change the shortcut accordingly.

Another basic q on R I have written the following function in an R script logistic <- function(r,x) r*x*(1-x)and saved it as logistic.RIm now trying to call it in the R console. How can I do this?I've set the wd to the same path as to where logistic.R is saved but still nothing....

You'll need to source it in. source("/path/to/file/logistic.R") or source("logistic.R") since it's in the working directory.

thanks
