similar to: strwidth

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 <-

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,

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

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 =

Hi, currently the "label" and "edgetext" attributes of a dendrogram are coerced to character before they are added to a plot with `text'. Is there a specific reason to do so (expect for the determination of the size of the character string to be plotted)? Otherwise one could plot the attributes directly via diff dendrogram.R /usr/src/R/src/library/stats/R/dendrogram.R

In the plotcorr() function in the ellipse package, I want to position things differently depending on the size of the labels. I can use strwidth to find out the length of the labels, but only when there's a plot window open: it won't open one. Question: What function call says: make sure there's a window open (i.e. do what plot() does before it starts plotting)? I don't think

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

I want to layout on screen a graphic bigger than the screen (width=16.53543, height=11.69291) but strwidth() and strheight() give wrong results. > x11(width=42/2.54, height=29.7/2.54, pointsize=12) > plot(1,1, type="n", xlim=c(0, 1), ylim=c(-1, 0), xlab="", ylab="", axes=FALSE) > strwidth("Whatever") [1] 0.08471151 > # Now resize the window and

Hi, I'm trying to use DIBuilder to build my debug info and export it into a PDB, but I don't understand the way some DIBuilder method work. My question might have a straightforward answer but I don't see it ... (and I can't find any example code using these methods anywhere). Indeed createClassType takes an "Elements" argument, and createMemberType takes a

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,

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, 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, 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

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

Hi, is anybody out there who knows APL and would help me to translate 52 lines of APL code into propper R? best, Torsten

I don't use SPSS but following through on your detective work can provide the likely answer. First note that both date numbers are evenly divisible by the number of seconds in a day, i.e. 24*60*60. This suggests that these numbers are seconds since some origin. Since we know "2003/02/11" corresponds to 13264300800 we deduce that the origin must be spss.orig <-

Hi Paul, thank you for responding. I indeed overlooked, that units="inch" gives stable results, independent of resizing the graphics window on the screen. And indeed I would find some way fiddling around to get my graphic done. However I see a general problem here and I would like a general solution: Obviously we are dealing with two coordinate systems: the graphics device size (call
