[R] please help me on this problem

[Yong Wang]

Dear all:
I am totally new to R, actually, statistics software.I get two very
simple, even stupid question:
1) where I should put the data file in order to use it , I tried to build
a
work dir in library( package:base) and save the text file (data) there,
then, I use read.table(filename), not work; I tried the full path, still
not work. I must have done something wrong.
2) is it possible to create a data file in R instead of put data in a txt
file and then save the file under R?
I tried to find answer from the introduction, failed.
I really appreciate your help, thank you very much.
best
