similar to: Using strwidth before plotting

Hello R users! I began with R and I must say that it is really nice. I have data with a lot of variables and have a problem to extract the pattern from correlation matrix. So I tried with plotcorr and it went fine. While I was reading the help page of this function, I found that ellipse display can be even better with use of different colors (the code is bellow). However I have a problem to

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 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

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 <-

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

Hi, This is not a bug, but an enhancement suggestion. "strwidth" only gives the width of the text according to the x-axis user coordinates, and similarly for "strheight". Even if the par setting "srt" is changed to rotate the text, the resulting width (resp. height) is in terms of the non-rotated text. Currently, if I want to know how much space to leave for

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 members, Is there a way to turn a strwidth of a string into a number of lines that ist needed to display the string when using par(mar = c(?,4,4,2)) #### x = 1:5 names(x) = c("ZZZZZ","ZZZZZzzzzz","ZZZlllll","TTTTT","Zzhtsddfg" ) par(mfrow = c(1,2)) par(mar = c(8,4,4,2)) barplot(x, las = 3, main = "8 is to much") par(mar =

I have been using the ellipse function from the car package and the covariance matrix to draw an ellipse around a group of points to show the confidence limits. However, the points are actually represented by 3 variables so rather than plot each pairwise combination of variables in 2D I would like to plot the 'ellipse' in 3D using the djmrgl package. Can anyone offer advice on how I can

I have empirical Bayes estimates for slopes and intercepts for a number of subjects and I would like to plot the slopes and intercepts with confidence ellipses. These ellipses would be based on the confidence intervals for the slope and intercepts (forming the major and minor axis of each ellipse), and the correlation in the slope and intercepts. The ellipse function in the car library

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

Hello, R-Help - I am trying to plot the results of an ordination from package vegan. The tricky part for me right now is getting the colors of the ellipses denoting the 95% confidence intervals of the group centroids to match the colors of the points for those same groups. >From and earlier post, I saw the code to make a plot of the ordination using different colors for my different groups.

Dear useRs, While exploring new R packages, I have found the Rattle. This screenshot http://rattle.togaware.com/rattle-correlation.png is very interesting (others are in http://rattle.togaware.com/rattle-screenshots.html ). Which function was used to produce this plot? Is such plotting of the correlation matrix a unique Rattle's feature? Unfortunately I have some weird problems with RGtk2

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

hello, sorry for posting what may be a simple question: i do have a matrix of coordinates (positional judgments, see below) and now want to calculate and plot the corresponding error ellipse. can anyone help me with the exact steps/syntax? > xyDat X Y 1 -0.49 -2.13 2 0.91 0.48 3 0.20 -2.80 4 -0.76 -3.23 5 -0.36 2.50 6 1.38 1.24 7

Dear all, I'd like to know how I could compute the parameters "yaxp" and (the y components of) "usr" without having to plot the data first. Note that "ylim" is /a priori/ fixed. The aim is to automatically adjust the parameter "mgp" without having to make the plot twice. Then, with "yaxp" and "usr" known, it should be easy to

good morning to the R-help list!, I would like to ask if there is an alternative to the S ploting parameter "cxy" in R. I am trying to port some S code to R that makes use of this "cxy" parameter to scale the graphics, and I don't find this parameter in help(par). thank you, IOsu ------------------------------------------------------------------------------- Jes?s

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

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.
