Thank you Ray and Jim.
It works with file.choose().

If it's a text document created with a Windows application, then it is very likely that the file name is really DATOS1.txt.  Another useful thing to do in Windows is to use file.choose() whenever you want to open a file:
DATOS1 <- matrix(scan(file.choose()), ncol = 8)
