setwd() analogue

["Iyue Sung" <isung@affinnova.com>]

Hi all, 

  I'm trying to specify the working directory from which to read in (and
write to) miscellaneous data.  
The documents and archives seem to suggest something like

> data.wd<-"C:\\Projects\\Data1"
> attach(pos=1, new.database(data.wd)) 

But then, I try to read in a simple file with:

> base<-read.table("myData.csv", sep=",", header=T)

without success.

Could someone provide a tip please?
Basically, I would like to use syntax that is analogous to "setwd()" in
[R].


Thanks,
Iyue
