Re: [Rd] feature request: optim() iteration of functions that return multiple values

I have done this using attributes: fr <- function(x) { ## Rosenbrock Banana function x1 <- x[1] x2 <- x[2] ans <- 100 * (x2 - x1 * x1)^2 + (1 - x1)^2 attr(ans, "extra1") <- 1:10 attr(ans, "extra2") <- letters ans } Not sure if this works in your case though. Cheers, Ott On S

Re: [Rd] R-Forge > GitHub?

Apparently your username/password are wrong. Can you clone/push from other repos? You do not need authorization when cloning a public repo, so even incorrect credentials may work (haven't tested this though). But for push you have to have that in order. I suggest you create ssh keys, upload tho

Re: [Rd] Testing for vectors

Thanks, Hadley for bringing this up:-) I am teaching R and I can suggest 5 different definitions of 'vector': a) vector as a collection of homogeneous objects, indexed by [ ] (more precisely atomic vector). Sometimes you hear that in R, "everything is a vector", but this is only true for atomic

Re: [Rd] row names of 'rowsum()'

I am referring to base::rowsum(), not rowSums(). For some reason I cannot access it's help on my computer but the online documentation (R-devel version) states: Value A matrix or data frame containing the sums. There will be one row per unique value of group Period. Above, the argument 'reorder

[Rd] row names of 'rowsum()'

'rowsum()' seems to add row names to the resulting matrix, corresponding to the respective 'group' values. This is very handy, but it is not documented. Should the documentation mention it so it could be relied upon as part of API? Cheers, Ott -- Ott Toomet Visiting
