[R] colSum() in Matrix objects

isted in the help for Class 'CsparseMatrix' , but I wonder whether I'm using the default colSums() or the one specific to CsparseMatrix... #example (z = Matrix(c(0,1,0,0), 10,10)) zr = rowSums(z) class(zr) # numeric; I'd like it to be a CSparseMatrix object Thanks a lot in

Re: [R] %*% in Matrix objects

rix but numeric, and then ( * ) is applied. Last, I shouldn't consider myself the most standard user of the matrix package, since my lineal algebra is really basic. But in any case, you should know that your package is being enormously useful for me. Keep up the good work. And

Dear all, This may seem obvious for some of you, but it got me thinking. Can one use correlations (or R^2) as data for an ANOVA? The case in hand: I have several models fitting the same data (individual fits per subject). The different models fitting the same guy will produce different R^2, I was

[R] rank in descending order?

Hi, Is there any simple solution to get ranks in descending order? Example, a <- c(10, 98, 98, 98, 99, 100) r <- rank(a, ties.method="average") produces 1 3 3 3 5 6 I would want this instead: 6 5 3 3 3 1 Note that reversing r doesn't work but in small examples. Thanks, -Jose -- [EMAIL PRO
