syskern (`Functions for writing code that is OS and R/S independent', an amazing description given the reality) fails Rcmd check on Windows, and also gives incorrect information where it does work. There are already correct OS-independent functions for these purposes in R. It appears not to be needed to run the other three packages in the dse bundle, but to be the only R package that

Below are a few problems I have encountered with the new checks being done in R-devel. 1/ I have two generics, test.equal and test.equal.tframe. The first checks that two objects are equal while the second checks if two objects have equal tframes (time frames). There is no reason these should have similar arguments but the check seems to think that test.equal.tframe is a method for test.equal so

Kurt The function tempfile is available based on some C code from Friedrich Leisch. The function unlink is fairly simple in unix but I haven't experimented elsewhere. In this regard, I have put together a small kernel set of functions to try to handle cross platform and R vs S issues. This is appended below and I would certainly appreciate feedback. The purpose of this kernel is so that I can

With some input from Martin Maechler and Martyn Plummer I think I now have a fairly good set of functions for handling R/S and OS differences, however, I still have two areas where I would appreciate input. These are largely S problems, not R problems, but I am doing this so I can write code to work on both. 1/ In Windows I have been trying to identify NT, 95, or 3.1, but Martyn (who claims to

A slightly revised version of my DSE package for multi-variate time series analysis is now available at <www.bank-banque-canada.ca/pgilbert>. This version works with R 0.90.1 (and not with R 90.0 or earlier versions). It can also be installed with install.packages(c("syskern", "tframe", "dse"),

Hi Does anyone know of any R routines to send emails from R, under Windows? I thought about writing such a facility using the R(D)COM package to drive e.g. MS Outlook, but I don't want to reinvent the wheel. I have found a function Sys.mail in the library syskern, but this only works under Unix by shelling out a mail command. Thanks, David

I've just been reviewing some functions in my syskern library. This library was set up originally to provide me with a way to program around small R/S differences and to encapsulate some operating system requests in one place, so that these problems would not be spread throughout my code. Over the years the need for many of the programs in this library has disappeared. I have always worked

One of the functions I would like to clean out of my syskern package is a program to send mail. This is a common feature other programs (e.g. bug.report) may use so I would like it to be included in R/base. I will volunteer to do this as it looks like a fairly straightforward dissection of bug.report but I have some questions: Has anyone done this already? Is "mail" a good name or

I'm having some trouble figuring out latest.start in the tframe package. The results seem a bit cloudy. Sample session: > library(ts) > library(tframe) Loading required package: syskern > t1<-ts(c(1,2,3,4,5),start=1) > t2<-ts(c(1,2,3,4,5),start=2) > earliest.start(tbind(t1,t2)) [1] 1 1 > earliest.start(tbind(t2,t1)) [1] 1 1 > latest.start(tbind(t2,t1)) [1] 1 1

In Windows, I tried to build and check Paul Gilbert's dse bundle with the command rcmd check ../library/dse It ran for a while and built the packages, then failed at the end with this: ** checking Rd files ... OK ** checking for undocumented objects ... OK ** creating syskern-Ex.R ... ERROR I get similar errors checking packages, but there make pkgcheck-foo works. I don't

Below is a revised version of my kernel of functions for isolating R/S and operating system differences. The main change is "date" which I've renamed "date.parsed" to avoid conflicts with the R and S date functions. The R call now uses system() rather than unix() to avoid warning messages in R 0.62.3.

Hi, As a project for a computer performance analysis paper I am taking this semester, I am going to look at the performance of the memory manager in R, with the aim of determining how fast it is and which areas most need improvement. The idea is that I will compare various versions of R, starting with 0.64.2, and then at a few stages in the implementation of the new memory management scheme (of

Below is a revised copy of my compatibility functions with additions from Martin. I expect I may need a new version when 0.6 arrives but I thought it would be worth circulating this in case it suggests anything which might be resolved before the release of 0.6 rather than after. Thanks to a few people for pointing out the R function machine(). I have a kludge below for determining the same

It would be nice to be able to initialize the random-number generator with a single long argument; I can see that in principle this could be done by writing an access method, do_RNGinit (or whatever) for RNG_Init. I had trouble with the technical details, possibly because of long/int incompatibilities. Any chance of this happening? -- Ben Bolker

I am trying to straighten up my DSE package to use require() as that seems to be a good mechanism. I have several packages: dse requires tframe which requires syskern which masks a few methods in base ( RNGkind rnorm runif). If I do require(dse) I get 3 copies of a six line warning (lots of white space) about syskern methods masking base methods. If I use library(dse) I only get 2. (I've
