similar to: Xyplot or Tin-R problem?

Hi all, I'm trying to find a way to get xyplot to produce a second set of axes outside the right hand side of the graph. This is my progress so far: EE <- equal.count(ethanol$E, number=9, overlap=1/4) xyplot(NOx ~ C | EE, data = ethanol, prepanel = function(x, y) prepanel.loess(x, y, span = 1), xlab = "Compression Ratio", ylab = "NOx (micrograms/J)",

Hi: (Tried to find a bug report about this issue, but was unable to find it, let me know if this is a known issue) I have been working on an interface to highlight xyplot panels on mouse overs in JavaGD but I have stumbled with what seems to be a bug in trellis.focus. I am using R 2.8 with lattice 0.17-15 *** To replicate the bug: 1.- display an xyplot. For example, from the xyplot help page:

Hi, I wonder if anyone knows how to control color and darkness of the background grid generated by ' type = c("g", "p") ' in a lattice plot (e.g., in xyplot). The documentation does not seem to offer a way to change them. Thanks a lot! Wen

Hi: I am using the package "KernSmooth" to do the local polynomial regression. However, it seems the function "locpoly" can only deal with univariate covaraite. I wonder is there any kernel smoothing package in R can deal with bivariate covariates? I also checked the package "lcofit" in which function "lcofit" can indeed deal with bivariate case. The

Hello, I would be very grateful if anyone could help with what seems like a simple lattice task. I want to use xyplot, where the symbols for the plotted points are taken from another column in the data frame. So if the data frame looked like: a <- as.data.frame(matrix(data=c(1,1,10,2,2,20,3,3,30), nrow=3, ncol=3, byrow=TRUE)) a V1 V2 V3 1 1 1 10 2 2 2 20 3 3 3 30 you would get

Greetings and happy new year! I am in the process of converting some of the old S-PLUS scripts from Visualizing Data (Cleveland, 1993) into lattice. In fact, I did most of it several years ago, and at the time, all of the scripts that contained loess() worked fine. Tonight, I ran most of the scripts again, but every one that I tried with a loess() call crashed R. I tried it in two sessions, one

I would like to draw smooth curves instead of polygons. I could not find any spline function to do that : given an x and a y vectors, they all take the x in increasing order. Is there a function to draw a smooth curve through a set of points in any order ? with many thanks in advance Alain Guerreau CNRS Paris [[alternate HTML version deleted]]

Hi, I'd like to plot 4 groups of data using xyplot and panel.superpose so that the points are overlayed on a single plot. For each group of data I'd also like a loess smoothed function (using panel.loess). I have tried the following: xyplot(series ~ time | gr, data=etable, panel = function(x,y, ...) { panel.superpose(x,y, ...) panel.loess(x,y,span=.15)

Hello This is a problem I encountered repeatedly and I found no answer that made me really happy. I hope it is not too trivial. I would like to give the concentration of a substance in a plot title: 5 ug/ml substance the '5' would be a variable and the ug should be micrograms (with greek letter mu). It is the mu that causes the problems for me. I failed using various combinations of

I am trying to replicate the following plot using Lattice: http://addictedtor.free.fr/graphiques/graphcode.php?graph=78 I'm having trouble with the lattice equivalent of the "oma" (outside margin) setting. I've been all through the Lattice documentation and others and also searched the lists. Below is sample code that demonstrates where I'm at (it should paste

Dear, I am doing some statistics analysis using R software. I am currently trying to implement your library locfit. I am using Win NT and R1.1.1 version obtained on the following Webmaster : http://cm.bell-labs.com/cm/ms/departments/sia/project/locfit/index.html When trying to run it, the following message appears: ********** Error in .C("guessnv", nvm = integer(1), ncm =

I have a question regarding the package LOCFIT of C Loader. After fitting a smooth surface (y modeled by two regressors), I can't seem to find a nice way of making a perspective (or other 3d plot). The contours don't look quite so good. It is meant to be used as illustration of smoothing to my students in regression analysis. Could anybody perhaps assist me in producing a

Hi all: There was a concern raised by reviewers of a manuscript of mine over the proper execution of a Pearson's correlation. In brief, this was undertaken in order to determine the relationship between the extent of wheel running (y axis) and ethanol intake (x axis) across three, separate 10 day periods in 7 animals. In the paper, the correlational plots for each 10 day-period had 70 data

I am trying to read and write database tables that have a date field in them. I am constructing a data.frame, then using dbWriteTable to create the table and dbReadTable to read it. >datatbl<-data.frame( dates, trialnum, fooddel, ethdel, trialtime, trialtype, deliveries, food, ethanol, fcumrec, dcumrec, rrf, rrd) >ifelse(startdate==filelist,

Dear R People: Could someone recommend a small example for spline regression, please? I would like to show this to my students, step by step.

One of many scripts to produce 4 lattice plots on one page keeps throwing an error. I've tried manipulating the file to eliminate the error, but have not been able to do so. The error is: > source('bicarb.R') Error in source("bicarb.R") : bicarb.R:15:1: unexpected symbol 14: 15: hco33 ^ The 'h' is in column 0 so the caret would be column -1, but it's

How do I specify a "tight" y-axis, where the plot completely fills the y-axis range, inside the prepanel function? For example, consider the following code: require(lattice) set.seed(12345) x <- 1:1000 y <- cumsum(rnorm(length(x))) prepanel.test <- function(x, y, groups = NULL, subscripts = NULL, ...) { if (is.null(groups)) { result <- list(ylim = range(y)) }

Hi, [I'mm cc-ing r-help on this, since some others might be interested (Tony Rossini is, at least)] Yes, I saw your mail and was wondering about what would be the best approach to do it. It's definitely not trivial, mainly because Trellis is not designed to handle factors on the x-axis (chiefly for convenience, as factors typically have long names which are difficult to write on the

Hi, there's a new version of lattice on CRAN (0.6-5) which will probably ship with R 1.6.1. It has a minor change in API which might affect packages using lattice -- only if they define panel/prepanel functions of their own. In previous versions, it was implicitly assumed that panel (and prepanel) functions would only be supplied _numeric_ x,y,z arguments, although I don't remember this
