Val, please take it slow, you are missing basic stuff here.
(1) Windows Explorer may hide extensions; the 'Type' column should
read 'R file' anyway.
* Yes I looked at it and it only shows type. To check I downloaded
another script with R extension "test.R" and the type column shows
the
exact extension(i.e., test.R).
*
(2) Script files are included in your workspace with the comand
source().
Please type ?source for details.
(3) You should call files with their path and extensions (in your
case
'Rossi.R')
I can open the script using this command,
* Rossi <- read.table( file.choose(),header=T)
*
*Why I can not open with this command?*
Rossi <- read.table("C:/Documents and Settings/Val/My
Documents/R_data/prd/Rossi.dat",header=T)
*David,
*You suggested to use ,
Rossi <- read.table(paste("C:/Documents and Settings/Val/My
Documents/R_data/prd", "Rossi.dat", sep="/"), header=T)
This is not working as well I got the same error message.
H0: there is no file by that name in that directory.
HA: (or Windows and the email process is mucking up the spaces in the
path). I do not "see" a space between "My" and "Documents" in the
email representation.
I originally asked and you never answered...HOW did your save
"Rossi" or "Rossi.dat"? Code and output ... we want all your code and
console output!
So, please reproduce complete code and complete error messages. There
are often details in those messages that new users are unable to decode.
Any help is highly appreciated
Val
Hope the above help,

The working directory is

The data file(Rossi.dat) and the script(Rossi.R) are in
"C:/Documents and Settings/Val/My Documents/R_data/prd"
How should I write to read the file?
source(???) # what should be included here?
Rossi <- read.table('Rossi.dat',header=T)
I still got the same error message.
Error in file(file, "r") : cannot open the connection
In addition: Warning message:

Thanks

Hi User's,
This might be a simple question but it is giving me a hard time
as I am
a
new user.
I installed R version 2.9.2 (2009-08-24)
1. I just copied a short script from Fox (2002) as a practice
and
wanted
to save it as Rossi.R.
How?
The system saved it without complain but when I looked at using a
windows
explorer it is not *.R file but only Rossi. Why this is
happening?
If you were to include the code, we perhaps could tell you. In its
default
mode Windows may be hiding the extension from you. (Or possibly
because
R
does not postpend file types and (I am now guessing here about a
package
I
have not used and don't even know if you are) neither does Rcmdr.)
2. the script and the data files are in the same working
directory.
When I
run the following script
Rossi <- read.table('Rossi',header=T)
No path specification. And ??? thought you said it was a script,
which
would have been loaded with source()
Rossi[1:5,1:10]
But this suggests you are using it as data. ????
What do you get when your type this:
getwd()
the working directory is > getwd()
[1] "C:/Documents and Settings/val/My Documents"
getwd()
Maybe if you tried (untested)... Nah ... not going to do further
guessing.
Read the posting guide and supply the missing elements.
I got the following error messages
Error in file(file, "r") : cannot open the connection
In addition: Warning message:
In file(file, "r") : cannot open file 'Rossi': No such
file
or
directory
Rossi[1:5,1:10]
Error: object 'Rossi' not found
Thank you for your help in advance
Val
