Dear list,

I am trying to prepare a handout showing how to use R for factor
analysis. As part of the exercise I want to save a correlation
matrix on a tutorial web page. I can save with no problem (saving
locally and then transferring to the web site). Although I can
load() the local file, I am having problems getting loadURL to read
the remote file. I have tried saving it as an ascii file or just
using the default format.

Using R 1.9.0 on a Mac with OS 10.3

I first saved the file:
save(big5r,file="big5r.txt",ascii=TRUE)
and
save(big5r,file="big5r")
I can load either version from a local file using load().

I then have moved these files to a webserver and tried to load them
using the loadURL() command.

Using loadURL() I get the following message

>loadURL("http://personality-project.org/r/datasets/big5r")
#the default format
Error: restore file may be from a newer version of R -- no data loaded
>loadURL("http://personality-project.org/r/datasets/big5r.txt") #ascii format
Error: restore file may be from a newer version of R -- no data loaded

I can list the second file using a web browser and I can move the
first file back to my machine and load it locally.
My problem seems to be with loadURL.

Any help would be appreciated.

Bill
