When I use a table, from a Schaum book, I see that for the 95 percentile, with v_1 = 1 and v_2 = 1 the value is 161. In the modern era, looking values up in a table is less than ideal. Therefore, I would expect R to have a function to do this and based upon my reading of the documentation, I would expect the following call to get the value I expect:
      pf( .95,1, 1)
However, it produces
     0.4918373
Therefore, I conclude that I am using the wrong function. What function should I use?

Thanks
Bob
