[R] trouble opening connection 64bit R with win7 64bit

[Hayes, Daniel]

Hi,

I just installed R 64bit under Windows 7 64 bit
When trying to readin files I get the following error message:

> >   source(file="C:\\Users\\me\\Documents\\My
PhD\\Modelling\\R\\Scripts\\Functions\\functions 20jan10.r")
Error in file(file, "rt") : cannot open the connection
In addition: Warning message:
In file(file, "rt") :
  cannot open file 'C:\Documents and Settings\DoHyeDan\My Documents\My
PhD\Data\Smoothing\R\Scripts\zscore references\cdcwfa.txt': No such file
or directory

The file I'm looking for is definitely exists:

> >  file.exists("C:\\Users\\me\\Documents\\My
PhD\\Modelling\\R\\Scripts\\Functions\\functions 20jan10.r")
[1] TRUE

I suspect it something with windows user rights or file properties but
am not sure what to do.

Any help is appreciated.

Thanks in advance,
Daniel Hayes
