R help - May 2012 - system() under windows [x] but not with Mac

Hey Guys,

i am kind of confused. Under windows the system() function works great, but
not with my mac.
  I have two questions:

1) What do i have to change. Using packages which require system or
eval(parse() everything is fine, but
when i try it myself "sh: cmd: command not found"
Under windows i use e.g system('cmd /c copy
"bild.jpg"',intern=FALSE )

2) I really love the Hmisc/latex function and want to be able to do it
myself. 
    How could i save a text in my notepad as name.txt

Thank you!!

There is no 'cmd' system function in MacOSX.

system("cp q.csv q2.csv")  # succeeds in making a copy of an existing
file in the working directory

I do not understand what the problem is. What is meant by "do it"?  
What is the "notepad"?

The Mac does not have an application called notepad, so you can't "save
a
text in [your] notepad". However, the Mac has TextEdit, and if you save
any file with the ".txt" suffix it will open in TextEdit when you
double-click on it in a Finder window (outside R, that is).

You could even, from inside R, type
  system('open name.txt')
and it will open the file in TextEdit, provided that the file is in what R
considers to be your working directory.

To save a file from within R, start by viewing the help pages for
  write.table
  sink
  cat
depending on what you want to save and how you want it structured in the
file.
