Hi all, Being a new user of R I am having some troubles, I hope to get some solutions.., I have tried looking everywhere but so far not been so successful. i have two matrices mat1=[1:26], mat2[1:47] there are some missing values in mat1[5:6,15:26] I want to calculate Pearson correlation "r" between mat1 * mat2 and also estimate the significance P-value between mat1 * mat2 By using> cor(mat1[2:26],mat2[2:47], use="pairwise.complete.obs")I was able to calcualte the Pearson correlation "r" between mat1 * mat2 I am not able to estimate the significance P-value using cor.test My Qs are? How to estimate significance P-value between variables of 2 matrices? OR is there any other approach to do this.. any idea or suggestions ?? thank you for your time, balaji [[alternative HTML version deleted]]
