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?
