[R] problem in testing data with e1071 package (SVM Multiclass)

Hello all, this is the first time I'm using R and e1071 package and SVM multiclass (and I'm not a statistician)! I'm very confused, then. The goal is: I have a sentence with sunny; it will be classified as "yes" sentence; I have a sentence with cloud, it will be classified as "maybe"; I have a

Re: [R] Strange lazy evaluation of default arguments

This is exactly as expected. See section 4.3.3 of the R Language definition or google around on "R Lazy Evaluation" for details. You should not "expect" R's semantics to be the same as other languages with which you may be familiar. Spending time with a good tutorial or two should help you sort

Yes, this is intended behavior, and it has everything to do with where the parameters are first referenced and nothing to do with debugging. -- Sent from my phone. Please excuse my brevity. On September 2, 2017 10:22:22 AM PDT, Matthias Gondan wrote: >Dear R

Re: [R] Strange lazy evaluation of default arguments

Dear Bill, All makes perfect sense (including the late evaluation). I actually discovered the problem by looking at old code which used your proposed solution. Still I find it strange (and, hnestly, I don’t like R’s behavior in this respect), and I am wondering why u is not being copied to L

Re: [R] Strange lazy evaluation of default arguments

Another way to avoid the problem is to not redefine variables that are arguments. E.g., > Su3 <- function(u=100, l=u, mu=0.53, sigma2=4.3^2, verbose) { if (verbose) { print(c(u, l, mu)) } uNormalized <- u/sqrt(sigma2) lNormalized <- l/sqrt(sigma2) muNormalized <-

Re: [R] Strange lazy evaluation of default arguments

Hello, One way of preventing that is to use ?force. Just put force(l) right after the commented out print and before you change 'u'. Hope this helps, Rui Barradas Citando Matthias Gondan : Dear R developers, sessionInfo() below Please have a look at the

Re: [R] Block comment?

Is the reason you want a block comment containing code (as opposed to arbitrary text) that you want to be able to easily run the commented out code? If so the 'if()' construct has the advantage that you only need to change code at the start of the comment, not at both ends. The if(FALSE) could

Re: [R] Block comment?

I agree, since one reason for block commenting is to include syntactically-invalid information (such as broken code) in the source code. However, block commenting is not wholly a good thing, as both the R parser and human coders often find it challenging to identify where the end of the block

Re: [R] Block comment?

Uwe showed an R code -ish way to do it. RStudio and probably other R UI's and IDE's -- which is the way most folks write code, I think -- also make it easy to do. Cheers, Bert Bert Gunter "The trouble with having an open mind is that people keep coming along and sticking things into it." --

Thanks for the very detailed explanation. I did not create the series using structure(), that was the result of dump() on an intermediate object created within tsdisagg::ta(), which is where I found the error in the first place. ta() indeed manipulates .Tsp directly, rather than using ts. I guess
