Hi All, I am new to the R program (only my 2nd day trying it out!) and this may seem like a really stupid question but I was wondering if someone could help. I have managed to calculate the pearson correlation coefficient for my data and now I have a correlation coefficient matrix with a whole slew of numbers. I was wondering if there is a way to only show the correlation coefficient values that are between +0.85 to +1.0 and/or -0.85 to -1.0 in the matrix table. Thanks in advance, Allen
selecting for values above or within a range in the data matrix

Maybe something like this: set.seed(1066) m <- matrix(sample(10, 20, TRUE), 5, 4) cm <- cor(m) ind <- which(abs(cm) < 0.85) is.na(cm) <- ind round(cm, 2) Peter Ehlers
Thanks in advance, Allen
