Hello, Actually you are right. I was looking on the wrong direction. But I still got some doubts about how to use those methods.
I want to open a file on the client machine, for example a txt tab-delimited, and create a dataframe with its information on R. I got to create a RFileInputStream object, using the openFile method, so it store the file information. Then I must use the read() method from the RFileInputStream to get file information. And finally, I should use the assing() method to relate the data with an R object. Is that right?
