Hi there, I migrated from Windows7 to Ubuntu (11.10) and am trying to get my R back online. I've switched from Tinn-R to RKWard which seems to work well. My problem at the moment is that I'm no longer able to read in the data file I was working on before. > popafr <- read.table(file="~/Documents/My PhD/Modelling/SAS/SAS datasets/SAS export sets/Final reference curve sets/SAS_for_R AFRO 11jan11.txt",header=T, sep="\t") Error in file(file, "rt") : cannot open the connection Calls: read.table -> file In addition: Warning message: In file(file, "rt") : cannot open file '/home/me/Documents/My PhD/Modelling/SAS/SAS datasets/SAS export sets/Final reference curve sets/SAS_for_R AFRO 11jan11.txt': No such file or directory > I get the same results with: >popafr <- read.table(file.choose()) >popafr <- read.table(file="SAS_for_R AFRO 11jan11.txt",header=T, sep="\t") The file is physically present in both the getwd() and the directory listed above even with the .choose option I receive the same error. Does this have to do with file permissions? I've tried running sudo su and then starting R in a terminal with the same error. any help is much appreciated. Hopefully yours, Daniel
