Dear Greg,
Thanks for the tip. As I am new in R can you please provide me a script how
do to so. It will help my learning process.
Thanks,
Asher

Hi,
I have 20*60 data matrix (with some NAs) and I wish to perfom a Pearson
correlation coefficient matrix as well as simple linear regression equation
and coefficient of determination (R2) for every possible combination. Any
tip/idea/library/script how do to so.
Thanks,
As hz

The correlation matrix can be readily obtained by calling cor() on the

Hmm, after reading one of your other posts, I am thinking you may
*just* want all pairwise combinations. This worked for me:
# Create a sample data frame with 60 named columns
x - data.frame(matrix(rnorm(1200), ncol = 60, dimnames = list(NULL,
paste(Col, 1:60, sep=''
# calculate the
Hi,
Thanks, the cor() works.
Regarding the simple linear regression equation (mainly, the slope
parameter) and r2. I think I was not writing it well. I need to do it just
for the columns. If I have a, b, c, d columns I wish to compute the relation
of there data, e.g., between a-b, a-c, a-d,
