This post is NOT a question, but an answer. For readers please disregard all earlier posts by myself about this question. I'm posting for two reasons. First to say thanks, especially to Dimitris, for suggesting the use of errorest in the ipred library. Second, so that the solution to this problem is in the archives in case it gets asked again. If one wants to run a k-fold cross-validation

I have a need to call and pass arguments to nlme() from within another function. I use R version 1.8. I have found an apparent way to make this work, but I would appreciate some comments on whether this fix is really appropriate, or there is another way to do it that does not involve changing the source code. I don't have enough experience to start changing the sorurce code of a library

Hi, I'm using metafor to perform a mixed-effects meta-analysis. I'd like to test whether the effect is different for animals and plants/whether "group" (animal/plant) influences the effect size, but am having trouble interpreting the results I get. I've read previous posts about QM in metafor, but I'm still a bit confused. I've dummy-coded the factors:

I apologize for posting on this question again, but unfortunately, I don't have and can't get access to MASS for at least three weeks. I have found some code on the web however which implements the prediction error algorithm in cv.glm. http://www.bioconductor.org/workshops/NGFN03/modelsel-exercise.pdf Now I've tried to adapt it to my purposes, but since I'm not deeply familiar

Hi, I'm trying to fit a multinomial logistic regression to my data which consists of 5 discrete variables (scales 1:10) and 1000 observations. I get the following error: Error in `row.names<-.data.frame`(`*tmp*`, value = c("NA.NA", "NA.NA", : duplicate 'row.names' are not allowed In addition: Warning message: non-unique value when setting

Can I use xapian for a search like: 'title' has the phrase "dinner jacket" AND 'color' == BLACK AND 'state' == MA AND 'size' == XL What about faceted search? Thanks

*I have the following function:* /plot_mi_time = function(mdata, miname) { mdata2 = mdata[row.names(hakat) == miname, ] print(mdata2) xcoords <- c(1,1,2,2,3,3,4,4,5,5,6,6) plot(c(xcoords), mdata2, xaxt="n", ylab="Expression", xlab="Time(h)", , main=miname) axis(1, at=xcoords,

I'd like to use stripplot for some plots because I want to use the jitter parameter. On the other hand, I'd like to use dotplot because I'd like to have the horizontal lines that it includes. dotplot doesn't have a jitter option and I'm not having any success with getting panel.grid(h=-1) with stripplot. Can anyone show me how to make dotplot-like lines on a stripplot? Or

For each level of the factor in dotplot, I have time points I'd like to connect with a line. In the example below, 'x' represents a starting time and 'd' a duration, and I wish to connect 'x' to 'x+d'. Ordinarily I would use Dotplot from hmisc for this, but I have not been able to find a time class that Dotplot will allow. I can get lattice dotplot to put

Hi, I want to control the plots in the output of the xyplot(). It is easier to explain it through an example: #------------------------------------------------------------- library(lattice); # months months <- c("Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep",

Hi, I have the following function that i use to plot graphs. plot_mi_time = function(mdata, miname) { mdata2 = mdata[row.names(mir_test3) == miname, ] # print(mdata2) xcoords <- c(1,1,2,2,3,3) plot(xcoords, mdata2, xaxt="n", ylab="Expression", xlab="Time(h)", , main=miname) axis(1, at=xcoords,

Dear list, is it possible to change the background color of dotplot's points? I tried in many ways but unsuccessfully Thanks in advance Gianandrea require(lattice) dotplot(variety ~ yield | site, data = barley, groups = year, pch=21) dotplot(variety ~ yield | site, data = barley, groups = year, pch=21, bg=c("2","3")) ??!!! -- View this message in context:

Hello, I have trouble adding an abline to a dotplot() from "lattice" package. For example, I would like to draw a line at x=3: > library(lattice) > x<-1:5 > names(x) <- c("a", "b", "c", "d", "e") > dotplot(sample(x)) > panel.abline(v=3) Produces a line on the left hand side of the origin. What would be a correct

How can I use row.names() as y-labels in Dotplot? How to set horizontal orientation for y-lables in lattice()? Dotplot(stcod1 ~ Cbind(statgh2,statgh2-1.96*segh2,statgh2+1.96*segh2)[og], subset=statgh2[og]>0.1, data=h2inqerrg02st, xlab="G", ylab=row.names(h2inqerrg02st)[og], main="") I have tried doing it with mtext() as well, but there is not enough space besides

There seems to be a bug in "dotplot" concerning the "cex" parameter. Setting cex has no effect on the character size of the labels of the points. This problem was posted to r-help today (Thu, 18 Jan 2001); the solution given by Brian Ripley (and Uwe Ligges) seems to work for me. Heinrich Rinner. > version _ platform i386-pc-mingw32 arch x86

Hello! In a grouped Dotplot, is there any way to set the color of error bars to be the same as the corresponding symbols? Example data: require(lattice) require(Hmisc) data(barley) Dotplot(variety~Cbind(yield, yield+2, yield-2)|year, groups=site, data=barley) I experimented with changing trellis settings of plot.line (as mentioned in the Hmisc documentation) as well as col.line settings in

Hi all, I'm a newbie R developer, am trying to dotplot a few graphs using a for loop. The following code works fine but once I wanna plot inside a loop, nothing happens. > for(i in 1:1){dotplot(y~x)} > y <- c(1,2,3) > x <- c('a','b','c') > dotplot(y~x) > for (i in 1:3) {dotplot(y~x)} (y and x depends on I in actual case) Nothing happens. I

In dotplot, what's the best way to suppress the unused levels of 'y' on a per-panel basis? This is useful for the case that 'y' is a factor taking perhaps thousands of levels, but for a given panel, only a handfull of these levels ever present. Thanks, Ben

When I create a dotplot in lattice, I frequently observe overplotting of the labels along the vertical axis. On my screen, this illustrates overplotting of the letters: windows() reps=6 dat=data.frame(let=rep(letters,each=reps), grp=rep(1:reps, 26), y=runif(26*reps)) dotplot(let~y|grp, dat) Is there a way to automatically scale the labels so that they are not over-plotted? I currently do

Hello everyone I have dataset containing a monetary value (ABS) and two factors (Fct, Group). I am able to create useful using: bwplot(ABS~Group|Fct) and dotplot(ABS~Group|Fct) Question: What do I have to do to overlay the dotplot with the bwplot (same data set)? I've found a couple of posts that hinted at the possibility of doing that, and checked the panel.superpose() help, but the info
