After searching for a while I found that there is a function dir.create() to create some directory. However I need to know whether such directory already exists or not, otherwise I will create that.

Just use

dir.create(showWarnings=FALSE)

This will create the directory if it does not exist, and do nothing if
it does. If showWarnings=TRUE, it will give you a warning that the
directory exists.

Cheers,
