Hi, I have a list of several hundred 2 dimensional matrices, where each matrix is n x m. What I need to do is that for each n,m I need an average over all the lists. This would collapse...

Hi, I have a fairly complex object that I have written a print function for. Thus when I do print(results), the R console shows me a whole bunch of stuff already formatted. What I want to do is to...

Hi Everyone, I recently have started using R again on a Linux box after spending several years on a Mac. Last I checked, the best way to use R was through EMACS using something like ESS. I remember that being...

Hi Everyone, I am implementing a special case of Random forests. At one point, I have a list of which I then sample for replacement. So if the list is 100 elements, I get 100 elements some of them duplicates...

Hi, Suppose I have array A with 100 elements all filled in with "N/A". Array B has 25 elements with actual values. Lastly, I have array C that provides a map of where to put the elements from array...

Hi, My package is failing during the check phase on the windows machine both in devel and on 3.7. Here is a link to the devel branch: https://bioconductor.org/packages/3.8/bioc/html/iPAC.html I don...

Sorry, I forgot to add that some of the entries in various matrices have NA in them. On Sep 12, 2010, at 3:40 PM, Gregory Ryslik wrote: > Hi, > > I have a list of several hundred 2 dimensional matrices, where...

Hi Everyone, I have a list of vectors like this (in this case it's 3 vectors but assume the vector count and the length of each vector is not known): [[1]] [1] 9 5 7 2 14 4 4...

Hi, Doing that I get the following: Browse[2]> Reduce["+",results] Error in Reduce["+", results] : object of type 'closure' is not subsettable Thanks again! Kind regards, Greg On Sep 12, 2010, at 3:49 PM, Phil Spector wrote: > Gregory - > Suppose...

Hi Everyone, I have written debugged and tested my code and it works (yay!). I recently tried to parallelize it (1 core/per tree) and when I run the code I get an error saying the object "control" was not...

HI Everyone, I am working with the following situation. I have n observations and j possible outcomes and each one of the n observations is assigned a class from 1 to j. Furthermore, this process is done m times (for...

Thank you both for your help! I was interested in how to get at either element specifically. Your solutions work fine though. If I need the first element its lapply(thelist,'[[',1) and if I need the second its lapply...

Worked great, thanks! On Sep 11, 2010, at 8:26 PM, <Bill.Venables at csiro.au> <Bill.Venables at csiro.au> wrote: > Is this the kind of thing you are talking about? > > ### 8< cut here 8< ### > A <- rep(NA, 100...

Hi Everyone, I am interested in taking the mode over several thousand matrices. I show an example below. For the [1,1] entry of my "mode" matrix that I want to create I would like to have a "2". For...

Hi Everyone, I am trying to figure out the spatstat package for the first time and am having some trouble. Unfortunately, I can't post my data set but I'll hopefully post enough details for some help. I want...

Hi, I seem to be having somewhat of an unusual data input problem with some of the data sets I'm working with and want to run a simulation on. in the first data set I'm looking at, I...

Hi, Thanks for the help! The prop.table definitely will save some time but my question is how would you actually build the "mat" matrix. What I have now is 1000 matrices that are nx1 which have a predicted value...

Hi, That seems to be the case. Is there a way that I can put an object in some global place where all the workers can access it? Doing the following at the start (before I make multiple workers) does...

Perfect! Thank you! On Mar 2, 2011, at 10:55 PM, <Bill.Venables at csiro.au> <Bill.Venables at csiro.au> wrote: > Here is one way. > > 1. make sure y.test is a factor > > 2. Use > > table(y.test, > factor...

Hi Mr. Turner, You are correct that I am confused a bit by the RCode. Basically, I have 3772 observations of data and only about 500 of them correspond to where "people" exist. For the other observations, I just have...
