Dear developers: I have observed a change in the behaviour of S3 method despatch (as I guess related to namespaces) between 2.6.2 and yesterday's 2.7.0 RC and would be grateful if you could comment on that: the 'Axis' function in the 'graphics' namespace calls UseMethod("Axis",x), internally to despatch on the S3 Axis method depending on the type of the argument.

Following my previous post on S3 method despatch, I put debug messages in the code of Axis, Axis.default and plot.default in graphics/R/axis.R and graphics/R/plot.R to print the class of x, at and y on plot. After recompiling R, what I see is that x *lost* its class attribute (at least for classes not known to 'graphics') in Axis, called directly from plot.default and this could be the

Hi. I'm using R1.3.1 on a x86 machine running Win 2000. My problem: - I want to convert a string to a date format using strptime. As I'm from Portugal my locale information is the following: > Sys.getlocale() [1] "LC_COLLATE=Portuguese_Portugal.1252;LC_CTYPE=Portuguese_Portugal.1252;LC_MO NETARY=C;LC_NUMERIC=C;LC_TIME=Portuguese_Portugal.1252" If I do the following

Looks like there is a buglet in 'installed.packages', around line 17: for (lib in lib.loc) { dest <- file.path(tempdir(), paste("libloc_", URLencode(lib,=20 TRUE), paste(fields, collapse =3D ","), ".rds", sep =3D "")) if (!noCache && file.exists(dest) && file.info(dest)$mtime >=20

Dear list: working with date/times I have come across a problem that ISOdate and ISOdatetime are too slow on large vectors of data. I was surprised just until I looked at the implementation and the man page: "ISOdatetime and ISOdate are convenience wrappers for strptime". In other terms, they convert data to character representation first in order to create a POSIXlt object that is then

Hi. I've already posted this question 2 months ago but as I've got no answer I've decided to try again :-) I'm using R1.3.1 on a x86 machine running Win 2000. My problem: I want to convert a string to a date format using strptime. As I'm from Portugal my locale information is the following: > Sys.getlocale() [1]

Hi, I am trying to define the as.POSIXct as an S4 method for one of my classes. Trying to define a generic, I am getting an error that it is already differently defined in base. However, if I query for it, there is no definition. Being in base, I also cannot really import it. If I define methods without definig a generic, they will work but with a warning that a new generic will be automatically
