Hello, ?colnames Regards, Pascal Le 20/09/2012 11:48, Kristi Glover a ?crit :
Hi R User, I calculated a correlation matrix and I was trying to give a same name for rows and columns (heading) in the correlation matrix. But, I was not able to do so. Would you mind let me know how I can assign the same name for the heading of row and columns in the matrix? I appreciate for your help. cheers, K [[alternative HTML version deleted]]

It does that automatically. Just assign the names you want to the data.frame before you compute the correlation matrix:
x <- data.frame(matrix(rnorm(100), ncol=5))
colnames(x) <- c("A", "B", "C", "D", "E")
y <- cor(x)
y
A B C D E A 1.00000000 -0.08053608 -0.05444754 0.02173336 -0.31879440 B -0.08053608 1.00000000 -0.02621494 0.16279797 -0.19011677 C -0.05444754 -0.02621494 1.00000000 -0.18518459 0.37355793 D 0.02173336 0.16279797 -0.18518459 1.00000000 -0.05316086 E -0.31879440 -0.19011677 0.37355793 -0.05316086 1.00000000
rownames(y)
[1] "A" "B" "C" "D" "E"
y <- cor(x) colnames(y)
[1] "A" "B" "C" "D" "E" ---------------------------------------------- David L Carlson Associate Professor of Anthropology Texas A&M University College Station, TX 77843-4352
