[R] Data Parsing

[Bernard L. Dillard]

Hello.  I have looked at R Site Search for this problem, and it didn't
give me exactly what I needed.

Consider this dataset called "results".  It has the following information:

Student      Day        Subject        Score

Mary          1          Math          Failed
David         2          Science       Passed
Bob           4          Reading       Passed
Marie         4          Reading       Failed
Jesse         3          Spelling      Borderline
Et cetera


My goal is to only do analysis of the data having to do those who passed
or who are borderline.  I want to ignore all of the data having to do with
those who failed.  I think part of the syntax is something like
results[-c("Failed")], but I'm not getting anywhere with it.

How do I create a separate data set containing all information on students
who either passed or were borderline?

Thanks.

Bernard
