[R] (no subject)

Hi, I had been using a script that works fine for several days and then I stopped using it for a month without having doubt that it would not be working. When I use it again today, I received an error when I reach the last step of generating the data file. *"Error in .jcall(wb, "Lorg/apache

[R] I have a question

Hi! my name is jeong in Sim. Now I'm studying MLE(Maximum Likelyhood Estimation) and MOM(Method of moments). I want to compare with the performance of MLE and MOM by making functions and drawing a plot. But I don't know how to do . so I want you to show me some R codes. First of all, I want t

Re: [R] Superpose two QQ-plots (gamma distribution) with, lattice function qqmath()

David, Duncan, Hi Following on David's rate argument try (with modifications of pch and grid) rate <- 1/4 shape = 8 rate = c(rep(1/4,100),rep(1/3,100)) I don't think the problem is related to the rate argument, which can well be vectorized, as is the case for a number of arguments in distri

Hi I think the answer lies in the allocating the distribution argument but I do not know how. Possibly with a prepanel function Duncan At 21:06 22/06/2013, you wrote: David, Duncan, Hi Following on David's rate argument try (with modifications of pch and grid) rate <- 1/4 shape = 8 rate

Re: [R] overlay 2 dot plots

Bert, you did judge all right, indeed, I do not have a clue about how lattice/trellis graphics works. With regards to "Feel free to demonstrate publicly that **I** don't have a clue if I have misunderstood or misjudged", thank you, but I will pass on that... I do not feel it is important for me

[R] Sparse Matrices and glmnet

Dear All, I am not going to discuss in detail the implementation of a model, but I am rather puzzled because, even if I manage to train a model, then I do not succeed in applying it to some test data. I am sure I am making some trivial mistake, but so far I have been banging my head against

[R] Which is the final model for a Boosted Regression Trees (GBM)?

Hi R User, I was trying to find a final model in the following example by using the Boosted regression trees (GBM). The program gives the fitted values but I wanted to calculate the fitted value by hand to understand in depth. Would you give moe some hints on what is the final model for this ex

Re: [R] Which is the final model for a Boosted Regression Trees (GBM)?

You need to read the papers referenced in the Help file. Except in trivial cases, there are NO simple models that you can fit by hand. Like many machine learning algorithms. -- Bert On Sat, Jun 22, 2013 at 6:18 PM, Kristi Glover wrote: > Hi R User, > I was trying to find a final model in the fol

Hi, I am new to this forum, and hopefully am sending the post to the right avenue (and in the appropriate format). I am planning to prepare a (to be commercially sold) book in near future, in which I expect to use some screenshots from R (running on Windows), and also graphic outputs from some of
