Dear members of R forum, I'm trying to perform a simply dynamic programming model in R, following the reccomendations of Soetart & Herman (A practical guide to ecological modeling). However, I've obtained a number of problems, that I'm unable to solve (even thoughI've tried during at least 2 hours). Can anyone help me? Many thanks > ccrit <- 0 > cmax <- 5 >

Dear R-Helpers Has anyone written a script for the dose proportionality assessement using the power model and the confidence interval criteria as described in - Gough at al. Assessment of dose proportionality: report from the statisticians in the pharmaceutical industry in Drug Information Journal,1995, 29:1039-1048 and/or - Smith et al. Confidence interval criteria for assessment of dose

Hi, not sure this is a bug or just an unavoidable undesirable side-effect -- or just me that does not do the right thing. Consider the code and output below. It creates 2 packages: * pkgA * pkgB that creates a method for a generic defined in pkgA Changes in a method for the generic in pkgA (after re-installing pkgA) are not reflected in pkgB, unless pkgB is re-installed against the new

HI: I need ideas on how to make this code shorter (maybe with a second loop?). The code as it is works, but in this case I only have 14 samples, but it will become insane with more, so I need a way to make it more automatic. The problem is that the output from ts1, ts2, and so on is a vector with more than one value, so I do not know how to solve this. Thanks Prenewbie The code is the

If I f = function() {} package.skeleton("PkgA", "f", path="/tmp") and then edit man/PkgA-pacakge.Rd to read in part \description{ More about what it does (maybe more than one line) \Sexpr{1} } and then R CMD build PkgA I end up with Saving output to ?/tmp/PkgA/build/PkgA.pdf? ...

Hello - I am having trouble extracting data from NetCDF data files using RNetCDF. The data files each have 3 dimensions (longitude, latitude, and a date) and 3 variables (latitude, longitude, and a climate variable). Here is some of the output from print.nc for clarity: ----- dimensions: month = UNLIMITED ; // (1368 currently) lat = 3105 ; lon = 7025 ; variables: float

I was wondering: are the downstream dependencies of a package rebuilt when a package is updated on CRAN? (I'm referring to the binary packages, of course.) The reason I ask is because there are cases where this can cause problems. Suppose that when pkgB is built, it calls pkgA::makeClosure(), which returns a closure that refers to a function in pkgA. Suppose this code is in pkgA 1.0:

Hi, SETUP: Consider three packages PkgA, PkgB and PkgC. PkgA defines a generic function foo() and exports it; export(foo) PkgB imports PkgA::foo() and re-exports it; importFrom(PkgA, foo) export(foo) PkgC imports everything from PkgA and PkgB: imports(PkgA, PkgB) PROBLEM: Loading or attaching the namespace of PkgC will generate a warning: replacing previous import by

Hello, I have a problem with ggplot and colors I used this function to draw somes lines and I want them to be all black (just to test) however, I dont get any black line in the figure. Do you have any experience with ggplot and manual colors?? ggplot(cmax, aes(cmax[,3], cmax[,6],colour=interaction(cmax[,1],cmax[,2]))) + geom_line() + geom_point() +

Dear All, I am trying to do the following, and could use some hints. Suppose I have a package called pkgA. pkgA exposes an API that includes setting some options, e.g. pkgA works with color palettes, and the user of the package can define new palettes. pkgA provides an API to manipulate these palettes, including defining them. pkgA is intended to be used in other packages, e.g. in pkgB1 and

Forgive my poor English. There is Tmax Window, the 1st windows XP compatible proprietary OS from Korea. Tmax company showed screenshot of Tmax Windows. But it is known as they mixed images with real XP and OpenOffice suite screenshots. http://mr-dust.pe.kr/entry/Tmaxwindow-screenshot-failed Tmax Window is doubtful about stolen ReactOS source code: This is a post of a tmax developer.

Hi, I have R 2.6.0 with updated lme4 and Matrix packages, and I am trying to fit a nonlinear multilevel model. I get the following error message: Error in nlmer(f ~ grModel(x, w, Tmin, Tmax, Topt, kopt, m) ~ kopt | flat, : gradient attribute of evaluated model must be a numeric matrix and I wonder what this may indicate. The nonlinear model I try to fit is as follows: > grModel

I'm trying to understand what goes on in the process that nls() uses. This converges without much drama: > rate.nls <- nls(Dev ~ exp(rho * (T)) - exp(rho*Tmax - (Tmax - T)/del)+ + lam , data = xx, trace = TRUE, + start = c(rho = 0.15, del = 7, lam = .02, Tmax = 30)) 599.7841 : 0.15 7.00 0.02 30.00 4.69849 : 0.14673457 6.83443060 -0.01417782

Hello, and please advise regarding any errors/omissions on my part. However, the documentation for R's tcplot function in the evd package appears to contain an error. I am using evd version 2.2-4 in R 2.14.0 with Windows XP. > data(portpirie) > mrlplot(portpirie) ## No Error > tlim <- c(3.6, 4.2) > tcplot(portpirie, tlim) ## Line from documentation Error in fpot(data, u[1],

Dear list, It seems that a package (pkgB) using another package (pkgA) with S4 generics formed by taking existing functions (for example 'plot') must not import the existing functions ('plot') in its namespace to avoid the warning "replacing previous import: plot". Suppose we use the simple 'import' directive in the name space of pkgB. pkgA and pkgB files would
