Hi, I was wondering if function eigen() does something different from the function call eigen() in SAS. I'm in the process of translating a SAS code into a R code and the values of the eigenvectors and eigenvalues of a square matrix came out to be different from the values in SAS. I would also appreciate it if someone can explain the difference in simple terms. I'm pretty new to both

Hi, I would like to know whether there exist algorithms to compute the coefficients or, at least, the degree of the minimal polynomial of a square matrix A (over the field of complex numbers)? I don't know whether this would require symbolic computation. If not, has any of the algorithms been implemented in R? Thanks very much, Ravi. P.S. Just for the sake of completeness, a

Hi, Try: dat1<- t(dat[,-1]) ?colnames(dat1) <- dat[,1] covmat <- cov(dat1) A.K. I'm running into this error and I'm not sure how fix it Error: is.numeric(x) || is.logical(x) is not TRUE This is my data frame geneExpression_Lab10.txt This is the homework instructions in case you want to see Lab10.pdf This is my code dat <-read.delim("~/Dropbox/Homework/R
