Dear Dieter, sorry for not being more specific. I would like to use R to get a prediction (with standard error) of the response in a mixed model at selected values of the fixed-effects factors. Hence, in a mixed model, say, for response body size with, say, fixed factors sex and age, I would like to get a prediction of size for each sex and at selected ages such as 5, 10, 15; and I want a SE

Hi, As part of the legend to a plot, I need to have the "n" in italics because it is a requirement of the journal I aim to publish in: "This study, n = 3293" Presently I have: legend(20, 105, "This study, n = 3293", pch=1, col=rgb(0,0,0,0.5), pt.cex=0.3, cex=0.8, bty="n") I suppose I could leave a blank in place of the "n",

Hi! Is there a way to get the string width of the bold typefaces? like: strwidth("text", family = "serif", font = 2). Thanks Roland

Dear plotting experts, I need to determine the width of a string before plotting it to the current device because I want to adjust `mai' to have the necessary space available. It seems to me that this is an "hen and egg" problem: R> a <- "test" R> strwidth(a) Error in strwidth(a) : plot.new has not been called yet # ok, I need an open device R> plot(1:2,

In platform i386-pc-linux-gnu arch i386 os linux-gnu system i386, linux-gnu status major 2 minor 0.1 year 2004 month 11 day 15 language R I'm getting an error when using strwidth after a lattice graphic is drawn: library(lattice) xyplot(runif(20) ~ runif(20)) strwidth('xxx') Error in strwidth("xxx") : invalid graphics state Any help

I have many functions for high-level plotting that early on in their code do something like strwidth('string', units='inches') before plotting. I do this before plot() to set the correct margins with par(mai=...), to leave room for wide text on the left or right margins. If the plotting device is not opened strwidth( ) causes an error that plot.new() needs to be called. I can

Dear R-users, When one defines a grid unit object using the 'strwidth' dimension, it seems that the default plain font is assumed as the following example illustrates. Is there a way to either make use of a font option when creating a unit object or to know the factor that exists between the width of the same text printed in plain and in bold? This might be dependent on the font,

Hello, I have a simple question that I could not really figure out. I am plotting labels within a graph using the text function. I first plot the first label by specifying the x and y coordinates on the graph. Then to plot the second label next to it, I am using te strwidth function to get the width of the previous label in user coordinate then add the maximum width to the x value. However, this

R users, I have a problem with function strwidth in 2.7.1. I'm trying to set the plot margins in a way that horizontal column labels will fit to the graph. tmp.t is a list of data.frame objects. This code works well in 2.6.0. ...snip.. library(gplots) for (i in names(tmp.t)) { bmp(filename=paste(i, "_", Sys.Date(), ".bmp", sep=""), width=1038,

Dear All, I would like to plot text with a box around it. I used strwidth and strheight to compute the size of the box which is plotted with rect: z <- rnorm(10) # horizontal text works plot(rnorm(10)) x1 <- 5 y1 <- 0 label <- "Label" cha <- paste(" ", label, " ", sep = "") xh <- strwidth(cha, cex = par("cex")) yh <-

Hello, I wish to customize the tick marks and labels of axes in panels produced by high-level lattice functions, namely xyplot. I know I can use the scales argument to specify values for rot, cex, etc. in the top-level call. However, I am interested in determining values for cex and rot based on the current panel / viewport and device. More specifically, I would like to make adjustments when

In help(unit) I read: The 'data' argument must be a list when the 'unit.length()' is greater than 1. For example, 'unit(rep(1, 3), c("npc", "strwidth", "inches"), data=list(NULL, "my string", NULL))'. In the newest R-versions it is not anymore allowed to let strings in the data-argument for plain units, otherwise one

Hi, First of all, thanks for the efforts of all the developers and contributors - I'm very new to R and at the moment am just using it to create some graphics, but it seems to be quite powerful. I've googled the archives and wasn't able to find anyhting that dealt with this problem, so would appreciate any suggestions/tips. In a pairs plot I'd like to plot a linear regression line

Dear R-Help I have some trouble to set the legend in a xyplot into two rows. The code below gives me the legend in the layout I am looking for, I just rather have it in two rows. library(lattice) schluessel <- list( points=list( col="red", pch=19, cex=0.5 ), text=list(lab="John"), lines=list(col="blue"),

Hello, I am using textplot function in gplots package to put some model output inside a PDF file, but it does not seem to work properly with PDF. I am doing follwing: pdf(file="C:/...", paper="a4", width=8, height=12) .model <- lm(.model.formula, data=database) textplot(capture.output(summary(.model)), valign="top", halign="left") I am getting these
