great!! thanks very much, mean(unlist(lapply(listdata, function(z) z$c))) works well. and what about getting the average table $a (displaying the average elements across all 1000 matrix)? could you please help me? I am struggling with this... thanks in advance Roberto mean(unlist(lapply(x, function(z) z$d))) should do the trick On Sun, 12 Feb 2006 20:06:12 +0000, statistical.model at

Hi, i need to create a fractional factorial design sufficient to estimate the main effects. The factors may have any number of levels, let's say any number from 2 to 6. I've tried to use the library conf.design , but i cannot figure out how to write the code. For example, what is the code for a design with 5 factors (2x3x3x5x2) and only main effects not confounded? thanks in advance!

Hi, I am trying to compute the Shapley Values between a set of p independent variables (x1, ..., xp) and the dependent variable y to study the relationships. I believe that the package "kappalab" could be an appropriate choice. Is anybody able to give me some hints about the code I should write? Any better package? thanks in advance!

hi all, I have a simple problem that i am not able to solve. I've a list called datalist with the following structure: [...] [[10]] [[10]]$a -1 0 1 -1 31 5 2 0 6 7 5 1 1 7 36 [[10]]$b -1 0 1 -1 31 5 2 0 6 7 5 1 1 7 36 [[10]]$c [1] 0.855 [[10]]$d [1] 0.855 [...] with [[1]] ...

I'm sure I'm being stupid so flame away... R2.2.1 on Windoze (boohoo) latest updates of packages.

Dear useRs, I'm writing regular survey reports using Sweave. Each report has several sections along the lines of: \section*{Disease X} <<MapX,fig=TRUE,echo=FALSE>>= image(vectorx,vectory,matrixz) @ Notes with or without Sexpr{a}. \vfill \pagebreak \section*{Disease Y} <<MapY,fig=TRUE,echo=FALSE>>= ...etc. Often one or more of the diseases is not observed (all

Hi, I am exporting an HDF5 file from Matlab (hdf5write function). It contains several datasets: one scalar, one vectory, one 2-D array, and one 3-D array. The hdf5read() function in the hdf5 library seems to load everything except the 3-D array. There are no errors reported even with verbosity=1, as if the 3-D array did not exist in the .hdf5 file. However, I can read the 3-D array back in using

Dear friends. I use nls() and encounter the following puzzling problem: I have a function f(a,b,c,x), I have a data vector of x and a vectory y of realized value of f. Case1 I tried to estimate c with (a=0.3, b=0.5) fixed: nls(y~f(a,b,c,x), control=list(maxiter = 100000, minFactor=0.5 ^2048),start=list(c=0.5)). The error message is: "number of iterations exceeded maximum of

Dear list, in the following loop im generating objects of type table. What I would like to do is to put all those objects together in a list (that i called cc).I did this but the result is not what i espect to get: cc=list() d=1 for (i in data) { cc=list(cc,assign(paste("n",d,sep=""),table(i,subsample$vD31NADD))) d=d+1} I know that this won't work properly:

Hey Nadav, I'd humbly suggest that rather than use 3 directly, you should add a shared constant between these two passes, so when one changes, the other doesn't need to be updated. It would also ensure this bit of info about what needs to be updated isn't only contained in the comments.. On Fri, Jul 26, 2013 at 4:07 PM, Nadav Rotem <nrotem at apple.com> wrote: > Author:

Hi Daniel, Maybe my commit message was not clear. The idea is that the SelectionDAG store vectorizer can only handle pairs. So, the number three means "more than a pair".

Hi Nadav, Okay. 1. The comment doesn't make this clear. I would suggest, at a minimum, updating it to mention pairs specifically, to avoid the issue in #2 2. If the day comes when the selectiondag store vectorizer handles more than pairs, and does so better, is anyone really going to remember this random 3 exists in the other vectorizer? I would posit, based on experience, the answer is

R-help readers, I''m having a problem with an R script (see below), which regularly generates the error message, Error in start:(start + (sample.length - 1)) : NA/NaN argument , for which I am unsure of the cause. In essence, the script (below) generates the start and end points for random subsamples from along a vector (in reality a transect (of a given length,
