[R] RDCOMServer
Hi there, I downloaded RDCOMServer and the related packages from Omegahat. Tried their R.Evaluator example. But failed to invoke any method from the client side. When I looked at R.Evaluator from OLE View (some Microsoft development tool for browsing all the OLEs), I got the following error message from R.Evaluator: CoGetClassObject failed Class not registered REGDB_E_CLASSNOTREG ($80040154) RDCOMServer's isRegistered method said R.Evaluator was registered. So, what's wrong? Thanks. __ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help

[R] persp colors
Dear R experts! I use image() persp() functions for color plotting z(x,y)-type graphics. In image() colors correspond to z-values, that's what I want. OTOH, in persp() the col option means: col: the color(s) of the surface facets. Transparent colours are ignored. This is recycled to the (nx-1)(ny-1) facets. but I'd like to persp()' colors behave like in image() function! Could you help me to solve this problem?

[R] Simulating a variable following an arbitrary distribution
Hi, I'd like to know if there's anything in R that could help me do that. Let's suppose I have a density function of a random variable, for example f(x) = (x^3)/4 0 x 2 and I would like to simulate it. For the common distributions (exponencial, gamma, cauchy) there are the r-functions (rgamma, rexp, runif, rcauchy, and so on).. But when the variable I want to simulate is not one of those, how should I procede? I read some references on the subject and saw that there are some algorithms that can do that, but I just wonder if there is any implemented in R?

Re: [R] Simulating a variable following an arbitrary distribution
Your specific example is a scaled beta. Therefore, 2*rbeta(1000, 4, 1) will generate 1000 random numbers according to that distribution. You can get the same distribution from 2*qbeta(runif(1000), 4, 1). We can generalize this last example to any case of interest. Example: df4 - function(x)(x^3)/4 pf4 - function(q)(q^4)/16 qf4 - function(p)(16*p)^0.25 rf4 - function(n)qf4(runif(n)) Then rf4(1000) will produce 1000 pseudo-random deviates following this distribution. hth. spencer graves Edgar Acuna wrote: Hi, Use the Inverse transformation method.

[R] extending subsets over another variable..
Hi, I've been trying to learn and use R for data analysis, and so far it has be OK. It is very slow with the aov command. But, other than that things are generally OK. Anyway, todays problem is one that I have looked in quite a few places to try to solve but to know avail. I hope the list can help. I have my data organized in the appropriate way (i.e. a data point on each row and columns for each variable). I want to divide my subjects up by a median. However, I don't want the overall subject median but a subset, and then to split the entire subjects data on that subset. I don't see a way to do that at all. Any help would be appreciated. to make things clearer, here is an example of how to split subject by median ss-split(s, ave(s$x, s$subj) median(ave(s$x,s$subj))) what I need to do is split by subject when s is further split by a sub factor.

Re: [R] want to write a package for R
Hello, You should start creating a separate directory for your package (e.g. foo). As a minimum you need three things: 1) your R functions (as .R files in directory foo/R) 2) documentation of your functions in .Rd format (look writing R extensions and function prompt(), they must reside in foo/man directory) 3) The DESCRIPTION file (in the foo directory). Everything else is made by R. Now run R CMD build foo in the directory above (where the subdir foo is lying). It was pretty easy to do on linux, with windows you probably need necessary tools as perl. Otherwise, it should be similar. Bundles are just collections of different packages, probably not for you right now. Perhaps it helps.

[R] Help - Curvature measures of nonlinearity
Dear colleagues, Von Bertalanffy model is commonly adjust to data on fish length (TL) and age (AGE) TL= Linf*(1-exp(-K*(AGE-t0)). Linf, K and t0 are parameters of the model. One main goal of the growth study is the comparison of growth parameter estimates between sexes of the same species, or estimates from different populations. The realibility statistical tests normally applied are highly dependent on the nonlinearity of the model used. Are there any developed routines in R ? to: 1) calculate the maximum intrinsic curvature 2) maximum parameter affecting curvature 3) plot the two dimensional cross sections of confidence regions (for different alpha values) of the model parameters Regards, Ivone Figueiredo [[alternate HTML version deleted]] __ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
[R] Rounding problem R vs Excel
For numbers ending in 5 Excel always rounds up and I want to reproduce this in R
rather than use the round function.
I have tried:
x-as.integer(x*100+0.5)/100
and
x-floor(x*100+0.5)/100
However, some values of x cause problems e.g
x-floor(4.145*100+0.5)/100
4.14
I have tried breaking it down into steps and force the results to 10 significant
figures in the following function, which seems to work
roundoff-function(x){
a-signif(x*100+0.5,digits=10)
roundoff-floor(a)/100
roundoff
}
Is there a more sensible way of do this for all numbers?
Thanks
