assume I have an "unstructured" text line from a connection. Unfortunately, it is in string format:

R> x
[1] "\talpha0\t-0.638\t0.4043\t0.4043\t-2.215\t-0.5765\t-0.137\t501\t2000"

How can I extract the data included in this string object "x" in order to get the elements for the parameter vector called "alpha0", i.e.  -0.638 0.4043 0.0467 0.4043 -2.215 -0.5765 -0.137 501

Any hints how to handle this would be appreciated. Best regards,
