Hi all, I was wondering whether it is possible to use the lapply() function to alter the value of the input, something in the spirit of : a1<-runif(100) a2<-function(i){ a1[i]<-a1[i-1]*a1[i];a1[i] } a3<-lapply(2:100,a2) Something akin to a for() loop, but using the lapply() infrastructure. I haven't been able to get rapply() to do this. The reason is that the "real"

...ement data for my project and I want to use quantile regression with multilevel or panel data in "R." I dont find the basic version of software in R, so I have difficulty in using it. I would also appreciate if anyone more proficient in R could help me how to run this. best wishes  M.A-Vakili Department of Biostatistics Faculty of Medicine Shiraz/Iran P.O.Box: 71348-45794 E-Mail: vakilima@sums.ac.ir  or mavakili@yahoo.com [[alternative HTML version deleted]]

Dear List, I'd like to call pyhton function from within R. I tried installing the latest version of RSPython: wget http://www.omegahat.org/RSPython/RSPython_0.7-1.tar.gz R CMD INSTALL --clean RSPython_0.7-1.tar.gz I get a compile error (posted below). Did anyone else run against this ? Is there a solution ? checking for python... /usr/bin/python Python version 2.6 Using threads checking

Hi list, in the Rglpk_solve_LP function (::Rglpk), on line 26, the function calls a function as.glp_bounds() that i cannot access. i'm trying to alter the Rglpk_solve_LP function to add a line to retrieve column/row dual values. everytime i change the slightest line of code inside Rglpk_solve_LP() [to even add a print] i get a ': could not find function "as.glp_bounds"'

Hi all, were can i find the sources for the function sample() (the one from the base package) thanks in advance, -- View this message in context: http://r.789695.n4.nabble.com/source-for-function-sample-in-package-base-tp4447796p4447796.html Sent from the R help mailing list archive at Nabble.com.

Hi all, I have this problem with lattice that xyplot() won't draw some of my axis labels if the type (i.e. the relation argument) of scales is set as free. For example, in the plot below, I would want it to also show: 1. the labels E1,...E6 below the 10th panel (i.e. 3rd row, 2 col)....just as it is now done below the 12th panel.... 2. as well as the labels (2,4,6,8) on the top of panels 1

Hi list, I have two question relating to the Rsymphony package: a) is there a way to use 'warm starts' ? i.e. if i successively call Rsymphony_solve_LP() with only one constraints change, does it perform the optimization from the simplex-origin or does it uses the previously found solution [i.e. as is common usage, see for instance lpsolveAPI] b) to what extend are sparse matrix

Is there any reason to expect a problem ? i'm running this script on the cluster down the hall: module load R/2.11.0 R library(multicore) fxx<-function(ll) runif(1) mclapply(1:10,fxx) i get: Error in fork() : Unable to fork. less /proc/cpuinfo yields: processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Xeon(R) CPU

Dear All, in the sources of robustbase, there appears a function called rPsort() (say l253 of qn_sn.c). I could not find its source in the robustbase package and a google search yields too many unrelated response. Can anyone point to its source ? thanks, -- View this message in context: http://r.789695.n4.nabble.com/Robustbase-source-question-tp3459966p3459966.html Sent from the R help

Hello, i'm using <R.h> & <Rmath.h>. What is the c equivalent to sort(x,deceasing=T) i.e. to get sort(x) i type R_qsort(x, 1, n), where do i set the decreasing=T flag ? More generally, is there a place where the functions in the R sources are documented ?

Dear List, I'm currently working on an R package that works great when compiled with GCC 4.8 under linux but which doesn't seem to work so well when compiled by the win builder (http://win-builder.r-project.org/). After asking around a bit, the primary culprit could be the older version of GCC used in Rtools. Now, for academic purposes, I would like to have a zip version of this

When I install an R package with cpp codes such as rrcov via CRAN (under R 3.1.1, using no Makevars file and under Ubuntu 14.04 using GCC 4.8), the cpp code is compiled with the -o3 flag (in fact, looking at the Makeconf file this seem to again be the default since R 3.1.1) But when I install my own package via CRAN it is compiled with the -o2 flag. My questions are what is causing my

Dear List, I'm trying to install Rcplex on a ubuntu 64 bit machine, and have not been successful.

Hi dear list, I'm scrambling with this: i have a p-dimensional data frame for which i want to have a pairs() plot, with ellipse added in each lower.panel. I want the ellipse's parameter (mu, sigma) to be extracted from the appropriate entries in a pre-computed matrix ("dab" in the code below). Can it be done ?

Dear all, I'm working on a project that links to the BH package (http://cran.r-project.org/web/packages/BH/index.html). My packages doesn't call entry points which might terminate R nor write to stdout/stderr instead of to the console. However, it seems some of the codes in the BH package might. At any rate, when I include some boost headers such as boost/math/distributions/ through BH,

Dear Prof. Ripley, Thank you for your answer. I think I am way over my head here. (Using Doker adds a level of complexity that I'm afraid I can't manage for now so I am happy with building Rdevel and using it in to run these tests). After building Rdevel with what I think are the correct options** (just to avoid mistakes I have also fully removed R from my system just before and

Dear All, I'm trying to implement the section of the manual pertaining to the gcc-ubsan test carried by CRAN on my local computer (ubuntu 14.04): http://www.stats.ox.ac.uk/pub/bdr/memtests/gcc-UBSAN/README.txt I was wondering whether someone could tell what the minimal version of the gcc tool chain needed to run the gcc-ASAN and gcc-UBSAN alignment tests on ones local

Hi all, I have been trying to add the line: h = n - p0 + 1; just after h = n / 2 + 1; (line 131) in the source code (the original paper mention this is possible for p0&lt;n). with p0 declared as an int (actually i used the same declaration protocol as n everywhere in the code). The &quot;new&quot; source compiles, but when i give it reasonable values of p0, it runs unto
