Subject: compare a vector and a row of a matrix
Date: Sun, 26 Sep 2010 23:23:52 +0800








Hi Everyone:

   I am trying to compare a vector and rows of a matrix
   for example
  > xn <- c(1,2,4,4,5,5,5,6)
  >yn <- c(1,2,5,7,1,2,3,1)
  >mtrx <- cbind(xn, yn)
  when I tried, say, > c (1,4), the result was TRUE, TRUE. I think the reason is that 1 is compared to xn and 4 is compared to yn seperately.
  Could anyone tell me how I can get a single result of the comparson between a vector and a row of the matrix?
  for example， c(1,1) is one row of the matrix but c(1,4) is not. I tried to write a loop but it seems long for this simple problem

Thank you very much!!!
