<URL: http://finzi.psych.upenn.edu/R/library/datasets/html/morley.html > "The classical data of Michaelson and Morley on the speed of light" Can you provide more information about the data? How were they obtained, etc.? I do not have the book "Genstat Primer" and the nearest location where it is available is University of York which is rather far from my location.

"An Introduction to R", Venables and Smith, Version 1.6.2 (2003-01-10) http://cran.r-project.org/doc/manuals/R-intro.pdf has in its "Appendix A: A sample session", page 81, file.show("morley.tab") I get the response NO FILE morley.tab The following "Introduction to the R Project for Statistical Computing" www.itc.nl/~rossiter/teach/sstat14/

Hi Ann Looks like a typo - I see "moreley.tab" that should be "morley.tab". Works for me after correcting that. > filepath <- system.file("data", "moreley.tab", package="datasets") > filepath [1] "" > > filepath <- system.file("data", "morley.tab", package="datasets") > filepath [1]

"An Introduction to R" has a sample session in the appendix. One of the examples looks at the Michaelson and Morley experiment to measure the speed of light and starts with "file.show("morley.data")". Where does one find this data table?

Hello! I was reading R-intro and I have some suggestions: R-intro.html#A-sample-session rm(fm, fm1, lrf, x, dummy) suggestion rm(fm, fm1, lrf, x, y, w, dummy) The next section will look at data from the classical experiment of Michaelson and Morley to measure the speed of light. file.show("morley.tab") mm <- read.table("morley.tab") suggestion mm <- data(morley)

Hi: I'm trying to do the sample session listed in Appendix A of the "Introduction to R" manual from: http://cran.R-project.org/manuals.html I've already downloaded R-1.5.1.tgz from: http://cran.r-project.org/ The problem is I can't find the file "morley.tab" which I need to start the sample session (as stated in the manual). Do you know where I can find it?

I am having what I think is a strange problem with applying TukeyHSD to an aov fit with error strata. TukeyHSD is supposed to take "A fitted model object, usually an 'aov' fit." aov (with error strata) is supposed to generate an object of type aovlist, which is a list of objects of type aov. But I can't seem to feed components of my aovlist to TukeyHSD. I guess I

I would like to plot two different samples on the same scatterplot in R using different symbols for the different groups. Could someone please let me know how this can be done? Thank you very much.

Dear all, I have the following output generated by linear regression. Since there is only one regression intercept and one slope for one set of data, what is the meaning of std. error for intercept and that of slope? Thanks in advance.

Dear List, I'd like to run a discriminate analysis on a data set, but have no idea how to go about this in R. I have attempted to locate info in the manuals, but may not be consulting the right sections or documents. Can anyone point me to appropriate documentation if such exists. Many thanks, David S.

Here's a nasty one. The following has caused a segmentation fault and possibly also a bus error. fred <- 1:6 dim(fred) <- 6 dimnames(fred) <- list(LETTERS[1:6]) mm <- matrix(1:12, 2, 6) mm %*% fred # segmentation fault here In the case without the dimnames assignment the result is OK.

Hi, I'd like to normalize a dataset by dividing each row by the first row. Very simple, right? I tried this: > expt.fluor X1 X2 X3 1 124 120 134 2 165 163 174 3 52 51 43 4 179 171 166 5 239 238 235 >first.row <- expt.fluor[1,] > normed <- apply(expt.fluor, 1, function(r) {r / first.row}) >normed [[1]] X1 X2 X3 1 1 1 1 [[2]] X1 X2 X3 1

Please, I would like to know how to generate a truncated multivariate normal distribution k - dimensional, X ~ NT(mu, Sigma), where the elements of X to be non-negative (except the first), and the first dimension is strictly larger than zero. Example: X ~ NT_2(mu, Sigma), where mu=c(0.5, 0.5) and Sigma=c([120, 191], [191,154]), with X_1>0 and X_2>=0 Could anybody help

I have a general style question about R coding. Suppose I'm writing a function (foo1) that calls other functions (foo2, foo3, ...) which have complicated argument lists (e.g. optim(), plot()), _and_ I may be calling several different functions in the body of foo1. Since foo2 and foo3 have different sets of arguments, I can't just use "..." ; I did write some code a while ago

For most cases, I''ve got search working in Rails as follows: ## controller: term = params[:search][:term] @results = MyModel.find_by_contents "#{term}*" The ''*'' character is appended to the search term so that searches match anything that begins with ''term''. For the most part, this is great, but let''s say term is equal to
