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!!!
