similar to: "trace" argument in legend() (PR#2578)

Hi, are there any plans to add a colorbar legend to image()? Or such a possibility already implemented which I just haven't discovered yet. Anyway, I will be willing to spent some time on the implementation if there isn't anyone working on that already. Thanks Thomas -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-devel mailing list -- Read

Dermot MacSweeney pointed out to me that after my "fix" of legend(), points were no longer coming out placed in the middle of the lines, but at the right-hand edge. It turns out that naively swapping the order of point-drawing and line-drawing also messes up the bookkeeping that legend() does on the current x-location. Here's my patch, which fixes that bookkeeping (and incidentally

Perhaps I should have submitted this as a bug so that it would be officially tracked. It's not a big deal, but here it is again (I can't remember which version this patch is against, but I don't think legend() has changed since then ...) Basically, the problem is that if you want to have "opaque" points that overlay lines (rather than using type="b" and having

Dear R users! I am using R Version 1.7.1, Windows XP, package "foreign" (Version: 0.6-1), SPSS 11.5.1. There is one thing I noticed with "read.spss", and I'd like to ask if this is considered to be a feature, or possibly a bug: When reading character columns, character strings seem to get filled with blanks at the end. Simple example: In SPSS, create a file with one

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];

Here is some tcl/tk code I am trying to emulate in R. Paste the following into wish ### begin tcl code toplevel .wtop proc evresp1 { data } { puts "evresp1 $data" } proc evresp2 { data } { puts "evresp2 $data" } bind all <<EVENT>> "evresp1 %d" bind all <<EVENT>> "+evresp2 %d" ### end tcl code Now paste event generate .wtop

Hello, In order to reduce the width of my legend in a plot I introduced line jumps in the title. Here's the problem; the legend box hasn't adapted accordingly and part of the title is printed out of the frame. See the example below: plot(1:10) legend("bottomright", bg="white", fill=c(7,8,12,13,19),

This is in the obscure corners of the tcltk interface, as I am sure you already realized... I'm not even sure whether the "+" in bind .... +script is syntactically an operator or part of the command. However, it is usually not right to define named functions on the Tcl side and mix them with the ones R/Tcl interface generate. So I am thinking that if

HI there, I want to add a legend to a plot using the density and angle argument, so patterns with lines in different angles are used in the plot and should be referred to. When I use default settings, the filled boxes are too small. With the cex argument I can enlarge the whole legend, but then the text gets too big. How could I just increase the size of the single boxes and not the text. I

In Version 1.1.0 Under development (unstable) (June 8, 2000) there seems to be a problem with an internal variable w0 in legend that generates the following new error: Error in legend((par()$usr)[1:2], (par()$usr)[3:4], Legend, lty = lty, : Object "w0" not found > -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-devel mailing list -- Read

Hi, The next CentOS Dojo is coming to Aldershot, UK - a 45 min train ride from London Waterloo station - on the 12th July 2013. We have a great, and growing list of speakers already on the agenda, and another few waiting to confirm. And, the venue sponsors - catn.com - are going to organise a hog roast barbecue and beet for everyone attending once the talks are done ( 4pm'ish ). So another

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]]

Hi all, I have two prodction servers with FreeBSD 5.4 (all security patches are applied). They running some services like dns, ssh, http, ftp, etc. But I woukd like to encrypt some services for some hosts with ipsec when it is accessed. For example: - DNS resolution: not encrypted. - DNS replication master-slave: encrypted by ipsec. - Telnet: encrypted by ipsec for some hosts. Deny

Dear all, maybe I have misunderstood something but to me it seems like a minor error in the help for ?legend for the argument 'bg'. There it says: bg: the background color for the legend box. (Note that this is only used if 'bty = "n"'.) I think, however, that it should be changed to: bg: the background color for the legend box. (Note that this

Hi R-ers: I'm drawing a plot and have used different line types (lty) for different race/ethnicity groups. I want a legend that explains what line types correspond to the different race/ethnicity groups. I used the following code: legend( 1992 , 42 , c("Hispanic" , "non-Hispanic white (NHW)" , "non-Hispanic black" , "AI/AN" , "Asian" ) ,

Legend titles work in linear plots: curve(1/x, xlim = c(0, 1)) legend(x = 'topright', inset = 0.04, legend = '1/x', lty = 1, title = 'Legend Title') But when you change to a log plot on either dimension things get screwy: curve(1/x, xlim = c(0, 1), log = 'y') legend(x = 'topright', inset = 0.04, legend = '1/x', lty = 1,

"contour" can't return a list of contours (it would be nice) "arrows" has different options from S-PLUS (no "open" or "rel" options, no "lwd" parameter or graphics parameter pass-through; "size" in S corresponds to "length" in R). [I know we needn't follow S-PLUS syntax slavishly, but it would be nice at least to

Greetings, I would like to add 3D arrows (i.e. arrow-headed vectors linking X1Y1Z1 to X2,Y2,Z2) to a 3D plot; ideally the sort of plot that can be rotated interactively. Is this possible using plot3d, or another 3d plotter in R? While it is easy to draw segments in plot3d (e.g. below), I haven't figured out how to add arrow heads, or to create 3d arrows from scratch. ##two headless
