After entering ?library(rpart)?, I tried to plot an existing rpart tree, and got this error message: Error: couldn't find function "plot.rpart". However, ??plot.rpart? does bring up the help for the function. The same things occur for text.rpart, although print(my.tree) does work. So, I tried to re-install rpart using Packages | Install from CRAN, but then I get this

Hi I have been trawling the web, FAQs, and R manuals for help on the following issue, but have failed and was wondering if anyone has a solution to the following problem: After having installed R 2.6.2 for Windows (binary), I tried to install various packages. Every time I try loading a package (any package) via the built-in menu, I run into the following error message. >

The file src/library/base/R/print.R contains this line: x0 <- xm[okP]==0 != (as.numeric(Cf[okP])==0) I didn't know R allowed that, and I wonder if it is deliberate? In mathematics, you would expect x = y not= z to mean (x = y) and (y not= z).; In R, it is parsed as (x == y) != z. While I have to admit that the spacing around == and != in

Dear all, i was working under R 1.6.2 but i wanted to install bioconductor under WinXP, and because R 1.7.1 contains the TclTk package and automatic installation of bioconductor packages, so i install it.

Hi, I'm using rw2000dev.exe (Win32) built on August 14. If this isn't already planned, can I suggest that when checkS3methods() (called by R CMD check) fails because of a syntax error in a dependent package listed in the DESCRIPTION file of the main package being checked, it would be nice if checkS3methods() reported which dependent package caused it to fail? Running R CMD check on my

Dear useRs, Lately I noticed a strange warning in the summary of a lm-object. Any idea what this warning is about?

Dear all, I have the following question. I have to fit the hierarchical model for the hypothesis concern the individual-level effects by controlling for the individual -level attributes and national-level contextual effects on individuals by using R.

Is there a way to add covariates to the system equation in a time-varying approach: Y[t] = F'[t]theta[t] + v[t], v[t] ~ N[0,V] #observation equation theta[t] = theta[t-1] + psi*Z[t] + w[t], w[t] ~ N[0,W] #system equation While F[t] is a matrix of regressors to capture the short term effect on the response series Y, Z[t] measures the long-term effect of either (1) two policies by a step

Hello everybody, I have a problem with accessing class attributes. I think it might be due to namespace access restrictions or something similar, but I'm unable to figure it out, maybe someone knows the trick how to do it ...

Hello, when trying to write an R-file, which automatically installs and updates a given list of packages, I had two problems with install.packages() 1) install.packages("<package>") will install <package>, no matter if <package> has already been installed. 2) the readline() at the end of install.packages, which asks the user, if the downloaded files should be

Hi, I am having a problem building binary packages for Windows recently. Normally, I use the "Murdoch-Sutherland" tool set, http://www.murdoch-sutherland.com/Rtools/ just build source packages by R CMD build <pkgname> and install these with R CMD INSTALL <pkgname> But now, for someone without having this tool set installed, under Win XP, with R-2.10dev

At the encouragement of many at UseR, I'm trying to build my first real package. I have no C/Fortran code, just plain old R code, so it should be rocket science. On a Linux box, I used package.skeleton() to create a basic package containing just one "hello world" type of function. I edited the DESCRIPTION file, changin the package name appropriately. I edited the hello.Rd file.
