Hi, I am sorry to say, I do not know where the 'morley.dat' is that is mentioned as the sample data for the sample session on page 80 of Appendix A in the Introduction to R book. If you could get back to me soon about that would be great! Then I can prepare my next question, steve __________________________________________________ Do You Yahoo!?

<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.

Hello all, I've tried to reproduce the contour plot that appears in the book of Venables and Ripley, at page 255. Is a F-statistic surface and a confidence region for the regression parameters of a non-linear model. It uses the stormer data that are in the MASS package. I haven't been able to reproduce the plot either in R ( version 1.5 ) and S. It makes the axes and it puts the

Dear all, I am doing 200 times simulation. For each time, I generate a matrix and define some function on this matrix to get a 6 dimension vector as my results. As the loop should be slow, I generate 200 matrice first, and save them into a list named ma, then I define zz<-sapply(ma, myfunction) To my surprise, It almost costs me the same time to get my results if I directly use a loop

Dear WizaRds! A trivial question indeed on selecting subsets in data frames. I am sorry. Unfortunately, I did not find any helpful information on the introduction, searched the help archive and read in introductory books. Please help: I want to select column "KB" which is read via read.csv2 as a data.frame into d. I checked that it is indeed a data.frame object and included the

Hi - I am using pls package for some pcr computations. There is a data set called gasoline. Would someone be able to tell me what command(s) could be used to produce this graph in R? I am not sure where the log(1/R) - Y-axis - are coming from Thanks much Ravi

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?

poly(NIR, degree = 2) will work if NIR is a matrix, not a data.frame. The degree argument apparently *must* be explicitly named if NIR is not a numeric vector. AFAICS, this is unclear or unstated in ?poly. -- Bert Bert Gunter "The trouble with having an open mind is that people keep coming along and sticking things into it." -- Opus (aka Berkeley Breathed in his "Bloom

Hello everyone, I have a simple histogram of gasoline prices going back a few years that I want to insert a line graph of consumer price index (cpi) over the histogram. I have looked through the "Lattice" book by Deepayan Sarkar but don't see anything there. How might this be done? An example would be wonderful. Current code snippet follows.
