First save your file as csv and then type the following in the console....assignname

This would open up your dcouments file and then you can select the file you saved as csv.

 Subject: [R] Using read.csv() to import data
I am just beginning to learn R, using _R for Dummies_ by Andrie de Vries and Joris Meys. I am using Windows 7, and RGui (64-bit) version 3.0.2. I have reached the chapter on "Getting Data Into and Out of R." But the code they use for importing data doesn't seem to be working for me.

Their example is:> elements <- read.csv(file.path("f:", "elements.csv"))
Since I don't have any such file, I am trying to use a file I have. I went to Excel, brought up my file titled JPH_data, and saved it as .csv (comma delineated) on my main hard drive C:

Then I entered:>  mammals <- read.csv(file.path("C:", "JPH_data.csv"))
I got the following:Error in file(file, "rt") : cannot open the connection
In addition: Warning message:
In file(file, "rt") :
  cannot open file 'C:/JPH_data.csv': No such file or directory
Aside from the obvious (how can it say "no such file or directory" when I just saved one such?), the "cannot open the connection" is also unexpected. What am I doing wrong here?
