Re: [R-SIG-Mac] I'm new to R in a Mac. How do I specify the path in read.table()?

[Parkhurst, David F.]

I’ve got it working now given help from several people.  Yes, I’ve used windows 
since it first came out, and DOS before that.  I switched to a Mac maybe 18 
months ago when MS said they wouldn’t support windows 7 any more, and I didn’t 
like my wife’s windows 10.  I’m still learning (and have just taken up R after 
not using it for years.). The Apple support people have taught me a lot!

David,

I thought I saw advice on this issue already that noted you could not use 
backslashes in file paths on a Mac. Have you tried with 
“/Users/DFP/Desktop/Monroe319Ecoli.txt”?  Do you come from a Windows background?

Wow.  That looks useful, especially when I don�t want to put the file to be 
read on the desktop.  Thanks.

Hi,

https://stat.ethz.ch/R-manual/R-devel/library/base/html/file.path.html

See the note at the bottom.  It's liberating in many ways that R handles the 
underlying details for you - use the forward slash and you'll be good to go 
without regard to the platform.

I think using file.path() is the best way to go. Just do something like the 
following...

filename <- file.path("Users", "DFP",  "Desktop",  "Monroe319Ecoli.txt")
x <- read.table(filename)

Cheers,
Ben

Thanks.  As I’ve said elsewhere, I thought I had seen in something I read that 
those double backslashes were required in a Mac.

Just use forward slashes, backslashes is a Windows thing. I.e.

read.table("/Users/DFP/Desktop/Monroe319Ecoli.txt")

should do it. A generic trick is

x <- file.choose()
dd <- read.table(x)

(and then possible have a look at x)
