Sorry. I have to modify my question. My codes were exactly as follows.
>>> import rpy2.robjects as robjects
>>> load=robjects.r['load']
>>> filename=robjects.StrVector(['test.RData'])
>>> x=load(filename)
>>> print(x)
"a" "b" "c"
>>> open(x[0])
Afterward, I got the following error.
RRuntimeError: Error in UseMethod("open") :
no applicable method for 'open' applied to an object of class "character"
