[R] basic inquiry regarding write.csv

[ronggui]

If the "file" is a relative path, then it should be in the working
directory. Say, the working directory is E:/my_work_directory (of
course, you can get it by getwd()), and you export a data frame "a" to
csv by:
write.csv(a, file="a.csv"), then the file should be
"E:/my_work_directory/a.csv".
