...load the class definition. I believe the error that occurs when we try to run `validObject` the first time happens in the `validObject` -> `getClassDef` -> `.requirePackage` set of calls. When `.requirePackage` does not find our package already loaded, it loads, attaches it, and returns the _package_ environment. This is different to what happens when the package namespace is already loaded, in which case the _namespace_ environment is returned. The problem with the _package_ environment is that any unexported class definitions will not be found there. This is why `validObject` fails the fir...

Does anyone know how to get cumulative frequency percentage and how to access library (equate)? Thanks. Grace [[alternative HTML version deleted]]

Hi! If i found a problem with the code of one of the libraries (not core), or, in my current case, would wish something minor changed for convenience, where can i get contact? Can i put it in the "official" bug repository? (Problem discription for anyone interested: Why call the default function kpca for a matrix with kpar=list(sigma=0.2), instead of putting this default sigma into the

Hi all, I'm tring to download the gpclib library but I don't find it in the old repository install.packages(c("gpclib"), dependencies=TRUE, repos="http://cran.cnr.berkeley.edu/") Avviso in install.packages(c("gpclib"), dependencies = TRUE, repos = "http://cran.cnr.berkeley.edu/") : argument 'lib' is missing: using

The Writing R Extensions manual instructs developers who use S4 classes and methods in a package with a name space to: There needs to be an .onLoad action to ensure that the methods package is loaded and attached: .onLoad <- function(lib, pkg) require(methods) I'm wondering if listing methods in the Depends field of the package's DESCRIPTION file is sufficient.

Hello R users and developers, I have a general question about reshaping a wide data frame using the "reshape" command. I have a data frame consisting of 108 columns that I would like to convert to a long table and remove the metadata (embedded in the column names of the wide table) to new metadata columns in the long format. #example data frame. NOTE column names contain metadata::

Hello ! I am completely new to syslinux. I followed this instruction manually: http://www.wonkity.com/~wblock/docs/html/pxe.html I am on debian and do not have syslinux installed, but using this debian box as a tftp server. I had to modify the instructions given by the installation above. I downloaded the 6.02 version and copied the files to the tftp root. I am using dnsmasq as a tftp

Hi guRus, i'm running R-2.15.1 and the R CMD CHECK output appears to have changed substantially, in that instead of pointing me to the offending functions or files, I get lots of 'call sequence' traces as below. I've been using R CMD CHECK for years & never seen anything like this before. This is on a pretty fresh OSX 10.8 Mountain Lion installation, where I installed R from

Dear alltogether, I experience very strange behavior of imputation of NA's with the NORM library. I use R 2.2.0, win32. The code is below and the same dataset was also tried with MICE and aregImpute() from HMISC _without_ any problem. The problem is as follows: (1) using the whole dataset results in very strange imputations - values far beyond the maximum of the respective column, >
