[R] Out-of-sample predictions with boosting model

Hi UseRs - I am new to R, and could use some help making out-of-sample predictions using a boosting model (the mboost command). The issue is complicated by the fact that I have panel data (time by country), and am estimating the model separately for each country. FYI, this is monthly data and I

[R] how to code it??

Hi I have say a large vector of 3500 digits. Initially the digits are 0s and 1s. I need to check for a rule to change some of the 0s to -1s in this vector. But once I change a 0 to -1 then I need to start applying the rule to change the next 0 only after I see the next 1 in the vector. Say for

[R] Odd crash with tcl/tk

Hi, Recently, I've been trying to use packages in R that require loading the Tcl/Tk interface. However, I get a strange result and a crash that I haven't been able to find discussion about on these boards (or any others). When I enter library(tcltk), it reads Loading Tcl/Tk interface ... , but

[R] error in f(x,...)

Dear all, I tried once to create one variable called bip such that: bip - cip + (1/f(cip))*fi(f,cip) And this was working. But now, doing the same thing I did before, the software shows me the following message: Error in f(x, ...) : unused argument(s) (subdivision = 2000) I have the variable

If I take your meaning correctly, you want something like this. x - c(0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 1, 1, 0, 0, 1, 0, 0, 0, + 1) easy - function(x) { + state - 0 + for (i in 1:length(x)) { + if (x[i] == 0) + x[i] - state + state - 0 + if (x[i] ==

Ubuntu also uses ~ as a backup file syntax, but Ubuntu has a trash can where deleted files are located, so it would be easy to restore them. I would be surprised if Fedora didn't also have a trash can. -Original Message- From: r-help-boun...@r-project.org
