Bonjour, J'ai t?l?charg? SciViews Insider que je trouve tr?s convivial. Par contre, je n'arrive pas ? comprendre comment enregistrer un script R en type de fichier R justement. Mes programmes fonctionnent tr?s bien, mais SciViews me propose uniquement de les enregistrer au format txt sous un type de fichier "bloc notes". Comment les enregistrer avec l'extension .R comme le

Hello, I have to create help files on R. I used the "package.skeleton" function which allowed to me to create a personal package with my list of functions. But I don't understand what I have to install to use these. That needs the tools to build packages from source to be installed. I will need the files in the R binary Windows distribution for installing source packages to be

I'm trying to make a connexion beetween Excel and R. It works for simple requests but it seems that complexe functions won't work. Does anybody knows how complexe can be the data set and function used? Does it exist something else than the Erich Neuwirth Add-in (which is already really interesting) ? Thanks Nolwenn ----------------------------------------------------------------------

I'm currently having a problem with the new released Samba 2.2.5: I cannot print anymore on my shared printer. What is strange is that It worked fine with samba 2.2.4, but now I got an access denied whenever I try to access the printer... /var/spool/lpd/samba is chmod 777 and the username is in the group lp Here is part of my smb.conf: [global] workgroup = HOME netbios name =

Hi, I'm a new R user, with a lot of questions. At the moment I'm stoped on an error traying to fit a model: > x <- sandeel ## numeric data (2500-60000) > y <- Noss ## numeric data (0-1.2) > A <- 0.8 > B <- 0.6 > C <- 1/40000 > nls( y ~ A-B*exp(-C*x)) Error in match.call(definition, call, expand.dots) : .Primitive... is not a function I'm

I ran into a problem trying to make a plot from a file that's read using source. Basically, I have the following code in a file "plot.R" : library(nlme) data(Loblolly) fm1 <- nlme(height ~ SSasymp(age, Asym, R0, lrc), data = Loblolly, fixed = Asym + R0 + lrc ~ 1, random = Asym ~ 1, start = c(Asym = 103, R0 = -8.5, lrc = -3.3))

I'm trying to fit a Gompertz sigmoid as follows: x <- c(15, 16, 17, 18, 19) # arbitrary example data here; y <- c(0.1, 1.8, 2.2, 2.6, 2.9) # actual data is similar gm <- nls(y ~ a+b*exp(-exp(-c*(x-d))), start=c(a=?, b=?, c=?, d=?)) I have been unable to properly set the starting value '?'s. All of my guesses yield either a "singular gradient" error if they

Hello I?m need fitt growth curve with data length-age. I want to evaluate which is the function that best predicts my data, to do so I compare the Akaikes of different models. I'm now need to evaluate if changing the initial values changes the parameters and which do not allow to estimate the model. To do this I use the function nls(); and I randomize the initial values (real positive number).

Hi, I'm trying to combine a VBA macro and a R package. I've installed the R-(D)COM and the R-excel interface by Neuwirth. They seem to work both. However I would like to display the r-generated data in an Excel sheet as an array but I don't manage. Here is an example of my source: Sub doR() Call RInterface.StartRServer Call RInterface.RRun("library(mdnn)") Call

Dear all I encountered strange behaviour of augPred with virtually the same data First I made groupedData object. > mar.g<-groupedData(rutilizace~doba|int, data=mar) When I perform nlme on complete dataset I get an error with augPred > fit<-nlsList(rutilizace~SSasymp(doba, Asym, R0, lrc), data=mar.g) Warning message: c("1 error caught in nls(y ~ cbind(1 - exp(-exp(lrc) * x),

Hola a todos Les consulto por un problema con xtable y nlme, tomando un ejemplo del manual de nlme para obtener los resultados en latex utilizando xtable, se puede utilizar el siguiente código, pero hay un problema y causa error. library(nlme) library(xtable) fm1 <- nlme(height ~ SSasymp(age, Asym, R0, lrc), data = Loblolly, fixed = Asym + R0 + lrc ~ 1,

Hi All. I'm trying to run nlsList an getting an error that makes no sense to me. I have accuracy and reaction time data over many trials for each person (id) When I use nlsList code that is virtually identical to the example in the doc file I get the following error. I've tried everything I could think of and can't get around it. Any ideas what I'm doing wrong? **************

Hi Well, yes I tried it about two weeks ago but my post did not get through as it still awaits moderator approval. I could check which column is offending but actually it is only minor nuisance, I can live with selection of columns before fitting a model. What seems to me strange is that both full dataset and only selected colums gave me identical fit results but only one works within augPred.

Hello there, I am trying to fit an exponential model using nls to some data. #data t <- c(0,15,30,60,90,120,240,360,480) var <- c(0.36,9.72,15.50,23.50,31.44,40.66,59.81,73.11,81.65) df <- data.frame(t, var) # model # var ~ a+b*(1-exp(-k*t)) # I'm looking for values of a,b and k # formula # mod <- nls(formula = var ~ a+b *(1-exp((-k)*t)), start=list(a=0, b=10,

Hi folks, I am tearing my hair out on this one. I am using an example from Pinheiro and Bates. ### this works data(Orange) mod.lis <- nlsList(circumference ~ SSlogis(age, Asymp, xmid, scal), data=Orange ) ### This works mod <- nlme(circumference ~ SSlogis(age, Asymp, xmid, scal), data=Orange, fixed = Asymp + xmid + scal ~ 1, start =

Dear Rusers, How would I plot several (24) fitted curves (nonlinear least squares) within a single plot? To get the parameters I use: resff <- list() for (s in levels(PairID)) { resff[[s]] <- nls(Photo ~ SSasymp(Ci, Asym, lrc, c0), subset = (PairID == s)) } Is it also possible to plot two different groups (male, female) of curves in the same plot, with different style lines?

Ok, I solved the problem by myself. The problem was that the users with wich I tried to connect to the printer where defined as admin users, and I declared root as an invalid user in the samba configuration, so it always give me an access denied because it tried to connect as root. Anyway thanks for the time you waste trying to help me ;-) ----Message r?exp?di?---- >Date: Thu, 27 Jun 2002

It got through just fine. It appeared on Aug 15. It just didn't get any replies. As I read your original question in this thread, it was not clear to me that you had
