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, type="n") R> strwidth(a) [1] 0.04760034 fine. But I can't continue to plot to the current device because I need to reset `mai', so I need a second one ... This is not re...

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 h...

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("c...

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(), "...

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,...

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 can use plot.new() or frame(), because I d...

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 se...

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 depen...

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 is not working: Here is an example: lab1<-c("Hocine & Ruba 2000", "Yasmine 2004","Ziad was born in 2006") lab2<-c(20,22,45) lab3&lt...

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 gets the following error: Non-NULL value supplied for plain unit I have some labels. Between th...

...er, 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 tick labels overlap on the x-axis, such as labels of a factor. If I use base graphics, par("cin") or par("cxy") or strwidth(), etc. can be used to develop an algorithm to adjust cex or/and rot if needed. I am trying to determine the parameters/settings in grid analogous to par("cin"), etc. mentioned above, knowing that par() has no effect in lattice / grid. I have dug around the sources for grid and lattice b...

...ce to know my device has 8 inches and that text x needs y inches in width. But the adress space in which plotting is done are the "user" coordinates. So, for the simplest example, specifying xlim=c(0,1) generates a stable reference WHICH DOES NOT CHANGE ON RESIZING THE GRAPHICS WINDOW. As strwidth(units="user") DOES CHANGE ON RESIZING THE GRAPHICS WINDOW the units arguably ARE NOT the user coordinates. I tend to believe this is a BUG. Same for units="figure". I also tend to believe, that resizing a graphics window should rescale the font size used ON SCREEN, because cur...
