Deepayan, Paul: Thanks very much for the very useful leads. I just spent some time this afternoon implementing your suggestions and my early test results are very encouraging. Paul, I understand the potential device re-sizing issue with the convert family of functions in grid, and will be in touch in case it becomes problematic for my applications. I very much look forward to your upcoming

Here are another three problems with logarithmic scales: 1) segments() does not work with logarithmic scales. I suggest to change lines 962-973 in "plot.c": for (i = 0; i < n; i++) { if (FINITE(xt(x0[i%nx0])) && FINITE(yt(y0[i%ny0])) && FINITE(xt(x1[i%nx1])) && FINITE(yt(y1[i%ny1]))) { GP->col = INTEGER(col)[i % ncol];

I want to right-justify a vector of numbers in the right margin of a low-level plot. For this I need to compute the line parameter to give to mtext. Is this the correct scalable calculation? par(mar=c(4,3,1,5)); plot(1:20) s <- 'abcde'; w=strwidth(s, units='inches')/par('cin')[1] mtext(s, side=4, las=1, at=5, adj=1, line=w-.5, cex=1) mtext(s, side=4, las=1, at=7,

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

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,

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,

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

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 often use something like old.par <- par(set someting) on.exit(par(old.par)) but in R 1.7.0. I now get warnings: > old.par <- par() > par(old.par) Warning messages: 1: parameter "cin" can't be set in: par(args) 2: parameter "cra" can't be set in: par(args) 3: parameter "csi" can't be set in: par(args) 4:

Is there a way to create a 'bubble plot' in R? For example, if we define the following data frame containing the level of y observed for 5 patients at three time points: time<-c(rep('time 1',5),rep('time 2',5),rep('time 3',5))

Hi all, I have some problems inserting data into a legacy table. the key field of this table is a field named CIN which is a varchar(15). when I try insert into this table using a form (generated by the scaffold generator) I get this Error : _____________________________________________________________________ undefined method `CIN_before_type_cast'' for #<Candidat:0x370d8c8> |

Has anyone tried to download Hmisc and used ldBands function for calculating Lan-Demets group sequential boundaries? The write-up in F.Harrell's website indicates that, besides downloading the package Hmisc, one needs to copy the progra ld98 from the University of Wisconsin website. As suggested, I did this but received another error message regarding the search path. I think I have fixed

Full_Name: Jonathan Paisley Version: 2.1.1 OS: Mac OS X 10.4.2 Submission from: (NULL) (81.178.107.67) I was following an example from library/grid/doc/grid.pdf ("Introduction to grid") and had the following code, where I'd mis-typed 1,3 instead of 1,2 as the first arguments to grid.layout. Sourcing this code causes the R GUI to crash. I've enclosed a partial backtrace from

There was too many spelling mistakes in my original post so I have decided to re-submit it. So here is it Dear R users, I am trying to determine how many characters can be displayed within the width of an open grid viewport. Unfortunately, the arithmetic operation that seems obvious in this case is not permitted with unit objects (see example below). Although there is a brute force way to get

Hi All, My group is looking for any suggestions on what to purchase to achieve the most powerful number crunching system that $50k can buy. The main application that will be used is R so input on what hardware benefits R most will be appreciated. The requirements are that it be a single standalone server (i.e. not a cluster solution), and it that must be able to run unix/linux. If

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,
