[R] R program for MacOS9.2.2

[Mark and Jenny]

Having trouble with this program which I have just downloaded for R program
for MacOS9.2.2. 

1. The download file on the CRAN site had a ? on the file to be downloaded.
Does this mean there is a problem with the file or does my computer have a
problem reading it?

2. On opening 'R' Initially comes up with Argument:____________ and choices
for console or file.    What am I supposed to enter here?

3. If I OK this and go to the 'copywright page, where it says to type
`demo()' for a demo it the comes up with a 'syntax error' What is a syntax
error?



If you cannot help with these questions, please could you email the program
with instructions how to install and use as I can not make any sense of the
FTP site.
Apologies for my ignorance.

Many Thanks
jenny
