Hi Huidong,
There are a few ways. One is to define a .First function in the 
directory where R starts and include the setwd() command in that:

.First<-function() {
  setwd("/home/huidong/R")
}

If you start up a new R session, create the .First function and then 
answer "y" to:

Save workspace image? [y/n/c]:

this function will be run when you start up R. You can add other 
commands to customize the R session, but remember to do so in a fresh 
session, then quit saving the workspace image each time you change .First.
