I am the proud owner of a new laptop since my old one died the other day.
Currently I have a dual-boot Windows 7 Home and Ubuntu 12.04 . I'll leave the Windows problems for another post.
I know practically nothing about Linux so I am probably doing something stupid but ... at the moment I cannot seem read or write files in Ubuntu. I am not having any problem saving other documents to the hard drive and R , from my few simple tests, seems to be working okay otherwise.
At the moment I am trying :
mydata <- read.csv("DATA/media/DATA/rdata/tt1.csv", header = TRUE)
or
mydata <- read.csv("DATA/rdata/tt1.csv", header = TRUE)
where tt1.csv is a text file on what, from my reading of the path listed in gedit is
DATA/media/DATA/rdata
The csv data is simply:
aa, bb
2, 3
4, 5
What happens:
-------------------------------------------------------------------------------
1> mydata <- read.csv("DATA/rdata/tt1.csv", header = TRUE)
Error in file(file, "rt") : cannot open the connection
In addition: Warning message:
In file(file, "rt") :
cannot open file 'DATA/rdata/tt1.csv': No such file or directory
Am I totally screwing up the path? Or doing something else equally stupid?
BTW I realise that 2.15 is out but Ubuntu as of yesterday did not have it in the repositories and I have yet to figure out how to install it from a CRAN site.
