Hello,
Please forgive me that this question is so basic, but i have not
been able
to find a solution in any of the basic R introductions, in the R
wiki, or in
the stats textbook i'm using to learn R. I run R on a macintosh,
and i have
not been able to load any data files yet. For instance, if I have a
data
table in a file called schools.txt on my desktop, i've been trying
to load
the table as such:
schools <-
read.table("c:\harddrivename\users\username\desktop\schools.txt",
header=T,row.names=1)
(obviously for the purposes of posting in this forum i've entered
generic
folder names.)
No matter how i ammend the path, i get the following error message:
Error in file(file, "r") : cannot open the connection
In addition: Warning message:
In file(file, "r") :
cannot open file 'c:\harddrivename\users\username\desktop
\schools.txt':
No such file or directory.
I'm guessing that there's a different way to enter the path name on a
macintosh?
Thanks for your help!
You are using a Windows based file path and on Windows,
snipped further useful information that does not need repeating:
Two further suggestions for a new Mac user;
a) this should have been posted to r-sig-mac:
https://stat.ethz.ch/mailman/listinfo/r-sig-mac
b) If you click-drag a file from the Finder to the R-console, you will
get a properly constructed full file specification. I generally
construct a landing zone with two apostrophes and thennavigate the
cursor until is sits between them:
read.table("", header=T,row.names=1)
.... and please do read the Posting Guide.
