Re: [R] Error in rep.int() invalid 'times' value

Thanks William. I've tried the first code, ( with f0() ), but still for n=25, m=15 , I got this: > s<-f0(25,15) Error in rep.int(rep.int(seq_len(nx), rep.int(rep.fac, nx)), orep) : invalid 'times' value In addition: Warning message: In rep.int(rep.int(seq_len(nx), rep.int(rep.fac, nx)), orep) :

Thanks for the hint Petr. I'm just a little bit confused with the function f1(). could you please help me and insert comments within f1() to be able to relate it with f0()? Thanks a lot. Maram Salem On 20 October 2015 at 11:29, PIKAL Petr wrote: > Hi > > What about

Re: [R] Transfer a 3-dimensional array to a matrix in R

Hi, Bill was faster than me in suggesting aperm() instead of apply(), however, his solution is still suboptimal. Try to avoid array(), and set the dimensions directly if possible. fn1 <- function(x) { apply(x, 3, t) } fn2 <- function(x) { array(aperm(x, c(2, 1, 3)),

Re: [R] Most appropriate function for the following optimisation issue?

Correction. Yes, it's the projection of S onto the subspace orthogonal to B which is: X <- S - (B%o%B) %*% S/ sum(B*B) and is also implied by Duncan's solution since that is what the residuals of linear regression are. On Tue, Oct 20, 2015 at 1:11 PM, Gabor Grothendieck

Re: [R] Error in rep.int() invalid 'times' value

f0 is essentially your original code put into a function, so expect it to fail in the same way your original code did. f1 should give the same answer as f0, but it should use less memory and time. Bill Dunlap TIBCO Software wdunlap tibco.com On Tue, Oct 20, 2015 at 2:05 AM, Maram SAlem
