Re: [R] search through a matrix

I changed the condition to: highlyCor<-cbind(rownames(x)[row(x)[((x > 0.9)|(x<(-.9)))]], colnames(x)[col(x)[((x > 0.9)|(x<(-.9)))]]) Actually what I am trying to do is run factor analysis on this 923 by 925 x matrix but many of the variables where too highly correlated and so I got some message

Re: [R] search through a matrix

Just try to run x[row(x) == col(x)] . You'll see it's a vector. It's the same as diag(x) Dimitri On Tue, Apr 21, 2009 at 9:02 AM, onyourmark wrote: > > Hi again. Thanks. I get it now. > So row(x) is a matrix with just the row number for each entry. > > How about x[row(x) == col(x)] ? > Can the sq

Re: [R] search through a matrix

Hi again. Thanks. I get it now. So row(x) is a matrix with just the row number for each entry. How about x[row(x) == col(x)] ? Can the square bracket function take a matrix as its argument? If so, I guess I understand this statement. The argument is a boolean matrix. Thank you. David Winsemiu

Thanks very much. I don't really understand the row() function. I looked in the reference but I don't really get it. It says: Description Returns a matrix of integers indicating their row number in a matrix-like object, or a factor indicating the row labels. Usage row(x, as.factor = FALSE) Arg
