Hello R Users: I have 3 packages that I authored and they build and check just fine locally. However, when I try to install the local source packages (from the .tar.gz), I get the following message: Error in `+.POSIXt`(as.POSIXct(origin, tz = tz, ...), x) : could not find function "%is.a%" In addition: Warning message: In install.packages(file.choose(), .libPaths()[1], NULL, type =

I am a new R user, and am looking to call Postgres through R. I am not so technical and need help in setting up. I have downloaded the tar file but cannot get passed this step. Is there documentation for dummies to get working with this? I don't even know where I should save this file? [[alternative HTML version deleted]]

Hi all, I'm trying to install the splancs contributed package on a Redhat 7.3 system with R 1.5.1 installed. I've installed the readline41-4.1-10 RPM which Redhat requires for R and it works great, thanks very much. However, when I attempt to R CMD INSTALL splancs_2.01-9.tar.gz as root, I get the following error message during the install: [snip] g77 -fPIC -O2 -m486

Hi R, I wanted to know how do we access the elements of a list. In particular, v=list(c(1,2,3,4,5),c(1,2,33,4,5),c(1,2,333,4,5),c(1,2,3333,4,5)) I want to access all the thirds items of the elements of the list. i.e., I want to access the elements, 3,33,333,3333. This can be done through sapply as: sapply(v,function(x) x[3]) But I need to access this without using

Greetings! Recently when I tried to use lm.influence I get the following error: Error in .Fortran("lminfl", model$qr$qr, n, n, k, as.integer(do.coef), : Fortran symbol name "lminfl" not in DLL for package "base" This occurs on both Linux and Windows platforms (details below). Searching the mail lists and other sources indicates that the fortran code for

Dear all, how can I use vcovHC() to get robust/corrected standard errors from an arima() output? I ran an arima model with AR(1) and got the estimate, se, zvalue and p-value using coeftest(arima.output). However, I cannot use vcovHC(arima.output) to get corrected standard errors. It seems vcovHC works only with lm and plm objects? Is there another way I can get robust/corrected

Hi all, I am trying to download, decompress and read a csv file. My code: myurl <- "ftp://ftp.ncbi.nih.gov/pub/geo/DATA/supplementary/series/GSE24729/GSE24729_MitoNuclear_suppl_male_stats.csv.gz" # myfile <- "GSE24729_MitoNuclear_suppl_male_stats.csv.gz" # download.file(myurl, destfile=myfile, mode="w") # mycon <- gzcon(gzfile(myfile,

Hi, I ran into the following peculiarity involving S4 method dispatch and namespaces. I develop a package which have a namespace and which depends on 'pixmap' package, which itself does not have a namespace. Now, in my package I have a class which has a slot for objects from class "pixmap" and I want to have a "plot" method for this new class. Not to clutter the

Max and List, Could you advise me if I am using the proper caret syntax to carry out leave-one-out cross validation. In the example below, I use example data from the rda package. I use caret to tune over a grid and select an optimal value. I think I am then using the optimal selection for prediction. So there are two rounds of resampling with the first one taken care of by caret's train

I wondered if there were standard practices in CRAN for delivery of R source implementing functions in R packages. I has encountered a couple of packages where the gzipped version of source contains very little, primarily the Help files describing the functions in the package. In some cases I can find the source as the value of the function name. Given that these packages are released as GPL,

Hi all, I'm trying to use the package read.table within a foreach loop. I'm grabbing 500M rows of data at a time from two different files and then doing an aggregate/tapply like function in read.table after that. I had planned on doing a foreach loop 39 times at once for the 39 files I have, but obviously that won't work until I figure out why the segfault is occurring. The

Dear list, here is a problem I met when trying to use a method for an S4 object, without loading the package in which the method was defined. I do not know if this is a bug, or a mistake of mine. Normally, I think the package in which the appropriate method is defined is loaded automatically when calling the method. The problem is that if the package is indeed loaded automatically, the

Estimados Carlos y José Efectivamente deben ser librerías que faltan, desde RStudio para ratlle el error de xml desapareció al utilizar los repositorios de cran en ubuntu, como si instalaría cualquier programa. Hay otro error que aún no intenté solucionar, que es desde RStudio (aunque creo que instale algo de gtk ...), es el siguiente: > rattle() Installing package into

Como dice José normalmente son las cabeceras, (terminando en dev) . Para gtk prueba con sudo apt-get install libgtk2.0-dev Yo también estoy en ubuntu 13.10 y precisamente me pasó algo similar al instalar rgl, lo solucioné instalando libglu1-mesa-dev y algunas otras "dev".

I installed R (R-2.4.1-win32.exe) on a new computer with Windows Vista and a 64 bit operating system (hp dv9000 with intel core t7200). The base R runs fine, but I can not get any of the packages to load. From within R I choose install packages choose a site then a package. I tried installing 2 packages and get similar errors (see below), I just copied and pasted lines from R. Can anyone

Hello useRs I am trying to build a package for personal use and for making easier working with other people but I keep getting the same error message about the DESCRIPTION file not existing. when trying to install from a source tar.gz file: Error in .read_description(dfile) : file 'C:/Users/Propriétaire/AppData/Local/Temp/RtmpHFMONb/R.INSTALL647a3535/mypkg/DESCRIPTION' does not

Hi, I'm trying to plot an equation in two variables to get a feel for sensitivity to its parameters. I've run expand.grid to get made-up vectors of the combinations of the two independent variables, and am trying to plot the output of the dependent, M, against both the dependent in a 3d space. t <- 0:100 DBH <- 10:100 TxDBH<-expand.grid(t,DBH) time<-TxDBH[,1]

Hi: I am working on some code in a package I'm writing and I'm getting the warning below when I do the install on a newly installed fedora 16 OS. But when I run the same install on windows, I don't get the error. and when I used to run the install on Fedora 14 ( I missed Fedora 15 ), I didn't get the warning there either ? Does anyone know what the problem might be ? Maybe a

Hello, I previously submitted the below query to r-sig-geo, but have had no response. Before I start bothering individual maintainers, I wonder if anyone on this list has any experience with the package and (or!) can diagnose my problems? Thanks, Calum Hello, I am having a little trouble with plotKML and I am not sure whether to ascribe it to my incompetence (most likely), incomplete
