Error running sammon() in multiv package
When I try to run the "sammon" function of the multiv package, I always get this error message: Error in as.vector(dist(a)) : couldn't find function "dist" It happens even with example(sammon). I am running R 1.5.0 on Win98 and I have still installed R 1.4.1 but it doesn't work on the old R version with the older multiv package either. Is there a problem with the

acceptable p-level for scientific studies
Dear list members, I have a statistical question, that doesn't belong to this list, and I apologise for that in advance but I would appreciate your help very much. Is there some convention for selecting the a level for significance testing in scientific (e.g. chemical processes) studies? Most people use the 0.05 level but I could not find a reference to justify this. Why not 0.01 or 0.1?

question about AIC
Please, forgive my ignorance on statistics, but I have a rather simple question concerning AIC. Small values of AIC mean good fit of the model. How about negative values of AIC? Is a model with AIC=0.5 considered to have better fit than a model with AIC=-500? I couldn't find anything explaining this in the documentation or any elementary statistics textbook that I have at my disposal. Thanks

coplots with missing values
Hello - I'm trying to construct a coplot to check the residuals conditioned on a factor using the following formula, however I keep getting an error message. I've used the same formula for another data set and it worked fine - the only difference is that now I have missing values for each level (2 levels) of the factor. Is this the problem and how can I fix it. Thank you. > E2 <-

model constant relations
Dear list members, this is not an R question and forgive me for using the list for irrelevant questions, but this is the only place I know where I can find some good statisticians and I need an expert opinion. There is this power law kinetic model of the form: M=kt^n where t is the time, M is the fraction of drug released, k is the rate constant and n is an exponent related to the mechanism of

How do I add fitted curves to coplots?
G''day I''ve been performing an analysis of some data by a follow the leader method (Bad I know but it seems to work and I think I understand all the steps now) and I''ve run into a problem. The analysis is for all practical purposes identical to the non-linear mixed effects analysis performed on Ludbrooks Rabbit data in the second edition of Venables & Ripley (page

coplot row separatot line
Hi all, I could not find a way to add the dashed horizontal separator line to the top panel of a coplot (the one indicating which panel belongs to which range of the given variable a in y~x | a). This line should separate the ranges plotted in a row of panels in the panel matrix below (hmmm, hope this is reasonably clear). I like it because it enhances readability. I'll try a sketch: >

coplot and par
R 1.9.1 on Win2000 or Win98SE. I am using coplot as follows: coplot(AVG~LRPI| REGION) the output seems normal but I get: "Warning message: calling par(new=) with no plot" This is the only explanation that I have for being unable to use par() with coplot for changing the way the xlab and ylab appears. From within coplot I can change the text itself but not the font, fontsize, etc,

More than one series in a coplot
Hi! I would like to know, how do you plot more than one data series when using "coplot"? I think I know the answer if "plot" is being used: x <- 1:10 y <- 1:10 y2 <- 1:10* 1.1 plot ( y ~ x, type="n" ) points( y ~ x, type = "b", col = "red" ) # plot the points and lines for the first series points( y2 ~ x, type = "b", col =

coplot with png: disappearing grid lines
Dear useRs, When I use coplot() and output to png/jpeg/bmp, the grid lines from the scatter plots disappear. If I output to pdf() the grid lines are there, however I can't use it - I have many points, and the resulting PDF file is large and very slow to open and scroll through. (By the way, if I click File-Save As-png/jpeg/bmp from Rgui.exe, the grid lines are preserved - but I need to use

Coplot Given text
Greetings: I am unsuccessful in suppressing "Given : myvariable" from a coplot. There was such a question in the past but the thread breaks down. I am sure this is a "for dummies" question :-). I tried: coplot(myvar~myvar | myvar, show.given=FALSE, xlab="....", ylab="...", main=" ") and some other variations (including without main=" ")

coplot and xyplot and panel functions
Hi, I wrote a panel function called panelwhite.corplot. If i use this function in a coplot is working fine, but if i use same function with xyplot i get the error: Error using packet 1: plot.new has not been called yet ..... and so on filling all my plots. So with: coplot(be~ch|dbh1, envmetr1, panel=panelwhite.corplot) I get the expected result with: xyplot(be~ch | dbh1,

Bug in coplot()
I am using R0.63.1 under Windows 95. Settings of <number> and <interval> when coplot is called are ignored, except for generating a warning. For example: > data(quakes) > coplot(long ~ lat | depth * mag, data = quakes, number=3) Warning: parameter "number" couldn't be set in high-level plot() function The warning is repeated ad nauseum.

Coplot graph size manipulation
I am currently plotting a graph with the function coplot() conditional on two factors which gives me 36 sub-panels. I have a few questions in general about changing the size of the graph. My question follows : a) I have a fair bit of text to put on the margin sides using mtext(). What is the best way to shrink the whole graph to say 80 - 90% so that I can include a bit more words. b) Since I am

coplot with boxplot panel function
I am attempting to construct a conditioning plot with a pair of boxplots within each panel. The resulting plot has panels misplaced. One misplaced panel is on top of the subcomponent describing ranges of the conditioning variable. This is what I did: X <- cut(rnorm(200), 2) Y <- runif(200) Z <- rnorm(200) given.Z <- co.intervals(Z, number = 4, overlap = .25) coplot(Y ~ X | Z,
