similar to: Dates labels on axes in xyplot

I am using 'xyplot' in lattice to plot some data where the x-axis is a POSIXct date. I have data which spans a 6 month period, but when I plot it, only the last month is printed on the right hand side of the axis. I would have expected that at least I would have a beginning and an ending point so that I have a point of reference as to the time that the data spans. Here is some test

After a long and winding road (sorry but I'm a novice) I get to a final result which is quite close to what I need; nevertheless I would like to tweak a little further the xyplot so that I can get ***for each single panel defined by variable z*** a finer control over: -the x and y the limits: I would like to be the same for both axes; -the number of thick marks: again I would like to be same

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)",

Dear R devel I've been wondering about this for a while. I am sorry to ask for your time, but can one of you help me understand this? This concerns duplicated labels, not levels, in the factor function. I think it is hard to understand that factor() fails, but levels() after does not > x <- 1:6 > xlevels <- 1:6 > xlabels <- c(1, NA, NA, 4, 4, 4) > y <- factor(x,

Hi, I would like to use xyplot to create a figure. Unfortunately, I cannot find documentation in xyplot to specify alternating the x-axis tick labels with the x-axis tick marks. I can do this with the regular R plot function as follows. #A small version of my data looks like this data<-data.frame(matrix(ncol=3,nrow=12)) data[,1]<-rep(c(1,2,3),c(4,4,4)) data[,2]<-rep(c(1,2,3,4),3)

I using lattice to make some plots and I want to make the y-axis on some of these plots use a log scale. In the following plot: x <- 1:10 y <- 2^x xyplot(log10(y) ~ x) I get tick marks on the y-axis at 0.5, 1.0, 1.5, 2.0, 2.5, and 3.0. I would rather have just 3 tick marks at 1.0, 2.0, and 3.0 but labeled 10, 100, and 1000. I know this can be done using the "at" and

All, I have some data of animal movements that I'm plotting using xyplot() from lattice. I want to have the date (class POSIXct object) on the Y-axis and the animals longitude on X-axis. Eg. xyplot(date ~ longitude, groups = animal, data = my.data) with data like: animal ptt year month day lon date 125 03P0014 13273 2003 7 10 150.38 2003-07-10 14:03:48 126

Problem: How can I format tickmark labels of log scaled axes of lattice graphics in the usual `xxx'-Format (and not in the scientific format). Example: (according to the help-page of xyplot): In the first plot I get the xxx-Format, in the second plot I get the scientific format (10^xxx): data(sunspot) plot( 1:37, sunspot, log='y',type='l') xyplot( sunspot ~ 1:37,

Hi, I have a basic question about aligning date labels for the x-axis in an xyplot so that they align with the grid lines from the panel.grid argument. For example, with x <- data.frame( date = seq(as.Date("2005/01/01"), as.Date("2006/06/01"), length.out = 20), value = runif(20)) xyplot(value ~ date, data = x, panel = function(x, y, subscripts, ...) {

Hi, V1.8.0 seems to allow DateTimeClasses as the x argument in xyplots (lattice). For example: x <- seq.POSIXt(strptime("2003/01/01", format = "%Y/%m/%d"), strptime("2003/10/01", format = "%Y/%m/%d"), by = "month") y <- rnorm(length(x)) dat <- data.frame(x= x, y = y) xyplot(y ~ x, data = dat, type = "b")

Happy New Year to all R users! I have two short questions concerning a xyplot with a color key: 1) How do I properly place (align) the color key beside the xyplot? As you can see from the code listed below, the placement of the color key is not correct. I would like the upper and lower end point of the color key to be perfectly aligned with the upper and lower line of the xyplot. Adjusting

Good Morning, I am using xyplot to show two variables for each of several subjects as follows: xyplot(y~x|as.factor(ID), type="b", layout=c(7,9), scales=list(x=list(tick.number=3), y=list(tick.number=5))) This is almost exactly the code I used for an earlier project, the only change is the number of ticks, but I'm getting all kinds of craziness on my Y axis. I played around with

Hi, I try to put a legend in a xyplot graphic. xyplot(y~x|g,ylim=c(0,80),xlim=c(10,40),as.table=T,layout=c(2,3), ylab="N??mero de machos capturados",xlab=expression(paste("Temperatura (",degree,"C)")), key=list(corner=c(0,0),x=0, y=0, text=list(legenda),lines=list(col=cor, lwd = espessura, lty=linha),columns=7,between=0.5,betwen.columns=0.5,cex=0.8)) The problem

I would like to create an xyplot with varying y-axis limits and horizontal labels at the y-axis tickmarks. The following does not seem to work, although I think it should, going by the documentation for par. R version 2.5.1, Windows XP Prof. Thanks for a clue. Andreas Krause library(lattice) # axis labels for y-axis are horizontal xyplot(Sepal.Length ~ Sepal.Width | Species, data=iris) #

Hi, I'm trying to do something simple (I think) with lattice graphics. I want to have three xyplots in a single column, where the x axis for the three is a date range and the y axes are numeric. I tried doing the first chart, and ran into a problem. When I enter: xyplot (date ~ count) I get a well formed plot with the date on the y axis, but when I enter: xyplot (count ~ date) I get:

# I need to create an xyplot() where I control the specific order of # both my conditioning variables. The default code below plots the # data correctly (dispersed across all 14 columns), but fails in two # ways. Both the primary conditioning variable (Transect), and the # secondary conditioning variable (Offset) are in alphanumeric order, # rather than the specific order I need. # Here

I have a problem with lattice log scales that I could use some help with. I'm trying to print log y-axis scales without exponents in the labels. A similar thread with Deepayan' recommendation is here: http://tolstoy.newcastle.edu.au/R/e11/help/10/09/9865.html. For example, this code using xyplot produces a logged y-axis but the labels (e.g. "10^1.2") are not very

R-helpers; I tried to get a superscripted 3 in the following xyplot example but failed: >data(whiteside) >xyplot(Gas ~ Temp | Insul, whiteside, panel = function(x, y, ...) { panel.xyplot(x, y, ...) panel.lmline(x, y, ...) }, xlab = "Average external temperature (deg. C)", ylab = paste(paste("Gas consumption (1000", expression(ft^3),")"), aspect

Dear R users, I am trying to move the "xlab" string on my xyplot, without success, I would like it to shifted down, would one of you know a way ?

xyplot doesn't seem to want to label my x-axis with dates but instead puts the day-number for each date. begdate is the number of days since January 1, 1960 and was initially created by library(date) ... polls$begdate<-mdy.date(begmm,begdd,begyy) I create a new dataframe (pollstack) which includes begdate. In the process begdate seems to lose its date attribute so I redo it as: >
