similar to: strheight() crashes without opened device (PR#524)

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 <-

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

Yes, par(family="mono") would work, except that I get R segfaults from this sequence: > > plot.new() > par(family="mono") > par(cex=8) > strheight("foo") Process R segmentation fault (core dumped) at Mon Dec 20 16:07:56 2004 on R 2.0.1 (2004-11-15), Red Hat Enterprise Linux AS release 3 In my code I call strheight and strwidth several times in

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

If I have drawn a string with ``ltext( x, y, labels="first string" )'' how can a draw a second string just one line (or strheight("X") below the first string regardless of the size and scales of the panel? Thanks Wolfram

If these things bother you, could you please supply fixes? For some reason you omitted the part of the help page dealing with one of these (which is as documented), and I also think you are confusing `plot' and `device' sizes. The latter will be the displayed device surface, I believe. Nothing on the help page suggested that the fine details of the R read-only parameters will be as you

Ah, I'm using Exceed Hummingbird 7.1 as the X server.... It does have fixed width fonts, and it is happy with variable width fonts up to this extreme .... A little more fiddling shows that this succeds with a linux based X11 server, and that even plot(1,1) par(family="mono",cex=8) text(1,1,"foo") segfaults. I've tested values of cex. Anything above 2.1249

Dear all, the help of par() claims that cin and cra are c(width, height) but it appears to be rather c(height, width) Best regards Jens Oehlschl?gel > plot.new() > strheight("W", unit="inches") [1] 0.1354167 > par("cin") [1] 0.1354167 0.1875000 > version _ platform i386-pc-mingw32 arch i386 os mingw32

Is there any chance this functionality could be added to the

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 found it useful to have contour be able to do line widths ... hope that the guts haven't changed an enormous amount in the current development version ... the patches are relatively trivial, mostly going by analogy with lty and col (although in my ignorance it took me a while to figure out what UNPROTECT(2) was and why it should be changed to UNPROTECT(3) ... hope this is useful.

It's probably a beginner's question: How do I show text in boxes? That is, can I specify a background color for text output with text() ? The following doesn't work as I would expect: text(labels="123", 50, 0.5, bg="green") I've experimented with legend(),which will make the box too wide, and also with rect(), which doesn't know the extent of the text

Hi all, I am have some difficulty with the legend function. I need to add a legend to describe the different line types in a plot. The legend box is small. It did not include sufficient length of each line type to help distinguish the differnt line types. Is there a way to fix this. Thank you Hannah [[alternative HTML version deleted]]

R 2.4.1 on Windows XP. Question: In traditional graphics, is it possible to find out the height of a line of text in units that can be used in arithmetic and then in calls to text()? Context: I have written a function that draws a plot and then, depending on whether some arguments are TRUE or FALSE, draws various lines of text in the plot. The text lines may be turned on or off individually

Dear HelpeRs, I would like to do sg similar to: plot(c(0,100), c(0,100), xaxs="i", yaxs="i", type="n") txt <- paste("a =", a, "%\n b =", b, " km2", sep="") text(95, 95, txt, adj=c(1,1)) just with the "km2" formatted with 2 in a superscript. I thought txt <- substitute("a = "*a*" %\n b

Dear list members, Every "modern" OS comes with dozens of useless fonts, so that the current font drop-down list in most programs is overcrowded with fonts one never will use. Selecting a useful font becomes a nightmare. In an attempt to ease the selection of useful fonts, I began looking into sorting fonts using some statistical techniques. I summed my ideas on the OpenOffice.org
