I have a list that looks like this ... > have <- list(a=7,b=3,c=1) > have $a [1] 7 $b [1] 3 $c [1] 1 and I want to have a simple way to change it to the following without re-typing the values ... > desire <- list(a=c(7,7),b=c(3,3),c=c(1,1)) > desire $a [1] 7 7 $b [1] 3 3 $c [1] 1 1 In other words, I need to create the list in desire from the list in have. In my

I am attempting to create a plot with intervals "stretched" in the x-direction using plotCI() in the plotrix package. The same data provides an appropriate set of intervals when "stretched" in the y-direction but I only get a lower interval when "stretched" in the x-direction. The data are as follows mns <-

I am trying to define a general R function that has a function as the output that depends on the user's input arguments (this may make more sense by looking at the toy example below). My real use for this type of code is to allow a user to choose from many parameterizations of the same general model. My "issue" is that when I compile a package with this type of code in it I get a

I am trying to construct a two-way table where, instead of printing the two-way frequencies in the table, I would like to print the values of a third variable that correspond to the frequencies. For example, the following is easily constructed in R > fact1 <- factor(sample(LETTERS[1:3],10,replace=TRUE)) > fact2 <- factor(sample(LETTERS[25:26],10,replace=TRUE)) > fact3

I am trying to compare Vbert growth curves from several years of fish data. I am following the code provided by: http://www.ncfaculty.net/dogle/fishR/gnrlex/VonBertalanffy/VonBertalanffy.pdf. Specifically the section on VBGM Comparisons between groups. ? This code is pretty cut and dry. I am able to run it perfectly with the "fake" data that is provided. But when I run it with my own

Sorry for posting this twice, but I still have not solved this problem and am hoping for some assistance. I am attempting to write a function that is flexible enough to respond to the user providing a formula (with a data= argument) or not (similar to plot(x,y) versus plot(y~x,data=data)). I have found a method to work with this in a simple case but am having trouble determining how to

Hi All, I am running quantile regression in a "for loop" starting with 1 variable and adding a variable at a time reaching a maximum of 20 variables. I get the following warning messages after my "for" loop runs. Should I be concerned about these messages? I am building predictive models and am not interested in inference. Warning messages: 1: In

Hi all, I'm trying to load the quantreg package but keep running into problems no matter which method I have tried. Does anybody know what this error (below) means in plain language and what I might do to get this installed. I have not had problems downloading/installing/running packages in the past. thanks in advance, derek Begin R output: trying URL

Dear R-help, Has anyone been able to use the quantreg package on Windows successfully? I tried to load it and get the following: > library(quantreg) Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library "C:/PROGRA~1/R/rw1031/library/quantreg/libs/quantreg.dll": LoadLibrary failure: The specified procedure could not be found.

Hi All, I'm still having significantly difficulty getting the quantreg library running in R. I'm running R on MEPIS using the debs created by Dirk Eddelbuettel and placed in apt testing. When I try to install quantreg using the install.packages() function it fails with: /usr/bin/ld: cannot find -lblas-3 Dirk was nice enough to send me a .deb for quantreg which installs without

Hi all, I'm having some troubles with the Quantreg package. I am using R version 2.10.0, and have downloaded the most recent version of Quantreg (4.44) and SparseM (0.83 - required package). However, when I try to run an analysis (e.g. fit1<-rq(y~x, tau=0.5)) I get an error message saying that the function "rq" could not be found. I get the same message when I try to search

Hi, I'm wondering if it is possible to install a package for R 2.0 on R 1.9.1 on Mac OS X? I'm getting this error which seems to be known issue: library("quantreg") Error in firstlib(which.lib.loc, package) : couldn't find function "lazyLoad" In addition: Warning message: package quantreg was built under R version 2.0.1 Error in

Hi All, I'm trying to install the quantreg library on my MEPIS box (debian-based linux). When I try >install.packages("quantreg") it fails to loads and errors with: /usr/bin/ld: cannot find -lblas-3. I tried installing a ton of packages to fix the missing part but the only thing I manage to do it cause problems with another shared library and had to re-install a couple of

Please, is there anyone who can give me some suggestions? (1) I have to use a package from R on my work. The package is the "quantreg" developed by Koenker (Uni Illinois). I have installed the package in the R library tree /usr/local/lib/R/ library of my Linux Operating System. I did R CMD INSTALL -l /usr/local/lib/R/ library /path/to/quantreg_x.y-z.tar.gz. However, when I call any

Just noticed that I get a similar error about object 'kronecker' in "Matrix" package when trying to load "lme4". So this is a more pervasive problem. Brian Brian S. Cade, PhD U. S.

After library(quantreg), ls("package:quantreg") will list all the names you currently export. So cat(ls("package:quantreg"), sep = ", ") will print the list in a form suitable for including

I recently lost the partitions on my hard drive (second time in 6 months) so I had to have our IT folks image all my files over to a new drive. I completely reinstalled R (now 2.15.2) and all my libraries to my computer (Dell Latitude running Windows 7). A few of my previous workspaces (created with R 2.14.1) can't be restored, reporting an error similar to the one I get when I try to

Dear all, I know that my question is somewhat special but I tried several times to solve the problems on my own but I am unfortunately not able to compute the following test statistic using the quantreg package. Well, here we go, I appreciate every little comment or help as I really do not know how to tell R what I want it to do^^ My situation is as follows: I have a data set containing a

You need to pay attention to the documentation more closely. If you don't know what something means, that is usually a signal that you need to study more... in this case about the difference between an input variable and a design (model) matrix. This is a concept from the standard linear algebra formulation for regression equations. (Note that I have never used RobPer, nor do I regularly
