Sometimes it is easiest to open a file using a file selection
widget. I keep this in my .Rprofile:
getOpenFile <- function(...){
require(tcltk)
return(tclvalue(tkgetOpenFile()))
}
With this you can find your file and open it with
rel <- read.table(getOpenFile(), quote="", header=FALSE, sep="",
col.names=c("id","orel","nrel"))
or
filename <- getOpenFile()
rel <- read.table(filename, quote="", header=FALSE, sep="",
col.names=c("id","orel","nrel"))

P.S. I keep a couple functions on hand for choosing writable files
and directories too...
getSaveFile <- function(...){
require(tcltk)
return(tclvalue(tkgetSaveFile()))
}
chooseDir <- function(...){
require(tcltk)
return(tclvalue(tkchooseDirectory()))
}
