Re: [R] Where to declare S4 classes?

The key steps are 1) setClass and setMethod calls are executed at the top level in your package See e.g. file mle.R in the stats4 package which ships with R. 2) The package is installed with SaveImage: yes or LazyLoad: yes. The stats4 package is shipped with R partly as an example of using S4

OK. Looks like I have got it... going through the source code of sp, classes are declared as usual functions in *.R files. With the current example, suppose I must write two files of names "class-Prior.R" and "class-SamplePrior.R" including setClass("Prior",representation(Distrib="character",Pa

Installing R on Knoppix Knoppix is a small LINUX distribution (http://www.knoppix.net/) runnable from a CD (without an installation) It can be also installed on a hard drive from a single CD. The idea was to reuse an old laptop with 6gb hard drive and 128mb memory. I had few days experience with

Hi Charles, Nice iniative for Linux newbie :) Some of us may have done a few things differently. I'll just point out one or two below. If you want to continue this discussion, why don't we carry it over to the r-sig-debian list that is more appropriate? I'll set the reply-to header accordingly.

Re: [R] what is scale function? Is it for variable transformation?

It will change the coefficients from lm and therefore their t-values but it will not change the residuals, fitted values, R-squared, F statistic, etc. For example, try this: set.seed(1) x <- 1:10 y <- x + rnorm(10) lm0 <- lm(y ~ x) # without scale lms <- lm(y ~ scale(x)) # with scale all.equal(fi

Hi, Paul: By my lights "paste" and "expression" work counter-intuitively. But as has been said here often, you CAN do it in R. Figuring out how might be a challenge, but you CAN do it (whatever it is). Here is some code that does what I think you intended. I also added some phantom characters

Try bquote (I may not have followed precisely what you want but hopefully this gives the idea). Note that you may need to use a few judiciously placed ~ and phantom(), as shown, in order to maintain syntax: plot(NA, xlim = c(0, 100), ylim = c(0, 100)) avar1 <- 10 amath1 <- bquote(slope == frac(p
