Dear R-helpers, I recently upgraded to R 1.9.0 in my computer at work and at home: 1.-The computer at home has Windows XP and Office XP and it seems to work perfectly and I copy-paste graphics perfectly. 2.-The computer at work has Microsoft Windows 2000 (5.00.2195 Service Pack 2) and Word 2000 (9.0.4402 SR-1) I cannot copy-paste windows metafiles into Office applications in my computer at

Dear R-helpers, I need some help to produce a set of contour plots that I am trying to make in order to compare surfaces between the levels of a factor. For example: library(lattice) g <- expand.grid(x = 60:100, y = 1:25, ti = c("a","b","c")) g$z <-with(g, (-1e-4*x-1e-3*y-1e-5*x*y)*(ti=="a") + (1e-2*x-1e-3*y-1e-4*x*y)*(ti=="b") +

Dear R-helpers, I am trying to reshape a data frame that is in a wide format into a long format one. I have come across the reshape() function, but I have been very successful using it. As an example: ll <- data.frame(time.1=seq(0.1,1,length=10),L1=rnorm(10),time.2=c(seq(1,7),rep(NA ,3)),R2=c(rnorm(7),rep(NA,3)),time.3=c(seq(1,1.5,length=3)+5,rep(NA,7)),M3=c (rnorm(3),rep(NA,7))) which

Dear R-helpers, I have some problem with a model I am trying to run with nlmeODE. I have a covariate that I want to include in the model and I can't find in the documentation how to include it in the model so that it can calculate it. >formula(trial) PME ~ time | Ident abcnoniso <- list(DiffEq=list( debdt = ~ -ksol*pH*eb , desdt = ~

Dear R-helpers, I’ve got a summary of results from a by() call that I am making with a list of more than two of factors not very different from the example in the by() help page require(stats) by(warpbreaks[, 1], warpbreaks[, -1], summary) The result of the command gives a list of the form wool: A tension: L Min. 1st Qu. Median Mean 3rd Qu. Max. 25.00 26.00

Last week (Wed 9/10/2003, "regression questions") I posted a question regarding the use of gnls( ) and its dissimilarity to the syntax that nls( ) will accept. No one replied, so I partly answered my own question by constructing indicator variables for use in gnls( ). The code I used to construct the indicators is at the end of this email. I do have a nagging, unanswered

I got a question from a fellow PhD student that work with spectrum analysis in Excel and now he has lots of spectrums that needs to be smoothed, which would be nice to be able to do in batch. Is there an R package that can do: Savitzky-Golay smoothing for reflectance spectral data or a function that does something similar. _______________________________________ Henrik Andersson

Hi there, I'm trying to fit a growth curve to some data and need to use a weighted least squares estimator to account for heteroscedasticity in the data. A weights argument is available in nls that would appear to be appropriate for this purpose, but it is listed as 'not yet implemented'. Is there another package which could implement this procedure? Regards, Robert Brown

I'm using Michel Fortin's MDTest cases to rewrite my html2text.php script. Just now I stumbled upon this bug (in PHP Markdown at least): # Input: Backtick: ``\``` # Output: <p>Backtick: ``&#96;``</p> # Should-Be Output: <p>Backtick: <code>`</code></p> If you (Michel) are already aware of this, just ignore me ;-) -- Milian Wolff

I am doing unit-tests for Maruku and every once in a while I run into some doubts. I am posting a lot to the list, but all of these messages should be in-topic (tell me if not). Consider the input: --- `There is a literal backtick (\`) here.` `There is a literal backtick (\\`) here.` ``There is a literal backtick (`) here.`` --- The documentation says that line 2 and 3 are equivalent.

A couple of months ago I downloaded R 1.6.0's binary for Windows, which I have since been using without any particular problem, that is on one machine running Windows 98. Last week I set up a local network and have since tried to use R remotely, i.e. R is installed on the previous machine and nowhere else. On the client's side, the GUI opens correctly and allows me to do simple

Dear Colleagues, Our group is also working on implementing the use of R for pharmacokinetic compartmental analysis. Perhaps I have missed something, but > fit <- nls(noisy ~ lsoda(xstart, time, one.compartment.model, c(K1=0.5, k2=0.5)), + data=C1.lsoda, + start=list(K1=0.3, k2=0.7), + trace=T + ) Error in eval(as.name(varName), data) : Object

Hi, I just tried to upgrade Nixpkgs to R 3.5.0, but unfortunately the new version fails its regression test suite. We configure the build using the flags "--without-recommended-packages", in case that's relevant. You can see a complete build log with all relevant information at [1]. Anyway, the test failures look like this: | make[3]: Entering directory

It seems that there are a few camps here: * The scp power users - this camp believes that scp supporting backtick notation is fine and that running arbitrary commands is a perfectly fine thing to do. * The restricted shell users - this camp believes that scp supporting backtick may not be the best, and there are various restricted shells which can prevent this. Power users may belong to this

Dear R-experts I would like to read all files from a directory, the files have names "myname0001.txt" etc. I paste the directory plus file names and use "read.delim()". My problem is that some file names are missing, so I get an error and my program stops. Is there a way to check for a null pointer analogous to C, so that I can simply skip non-existent filenames? Please do

I noticed just now that package.skeleton() produces R files in which the function names are escaped with backticks. ?Quotes says that "The preferred quote is the backtick (`)", but I don't understand _why_ this is preferred. ?formula gives some clues but points out that there are no guarantees that formulae using non-syntactic names such as `like this` will be accepted. What

Does someone out there have an example of R-code for a split-split plot ANOVA using aov or another function? The design is not balanced. I never set up one in R before and it would be nice to see an example before I tackle a very complex design I have to model.

Hi, I just edited http://wiki.centos.org/de/TipsAndTricks/BecomingRoot and formatted all the commands in section 1.1 as `monospace`. Since the main font and the monospace font look quite similar, it is sometimes difficult to see where one ends and the other starts. Therefore I propose to add the following CSS rule to the whole CentOS wiki: #page tt.backtick { background-color: #eee;
