Hello! When I draw points on grid's viewport with clip set to TRUE clipping does not have effect on some symbols. It happens only when drawing over gtkDevice (GTK ver. 1.2) (with postscript device clipping works OK - take a look at this screenshot http://www.hppi.troitsk.ru/Kondrin/clipbug.png) and only with symbols that are drawn with commands other than gdk_draw_polygon() (i.e. circles - gdk_draw_arc() - and squares - gdk_draw_rect()).

Hi everybody, I a, trying to use R as a pipe like this: cat inputData | R --silent RCommandFile >outputData The RCommandFile would contain something like readLines(stdin()). I have tryed various things and none did work cleanly. One possible solution is to use the pipe() function inside R and to pass in the "cat inputData" however this is not very convenient since I would like to

Hi, all, I would like to know if there is any gui interface out there (academic or commercial) that allows one to edit R-language generated graphs (e.g positioning x axis labels.) It would be nice to have something like the user interface of Igor or Origin. I have already used JGR and R-gui. These are good, but they don't allow one to easily edit graphs. I have also tried

Hello! There is a group of administartors of Russian internet site www.linuxportal.ru (this is mainly a forum for linux-users) who are intended to host on this site mirrors of linux distributions and open source software with http and ftp access. I have proposed to them to open there a CRAN mirror, making a point what this site would be a first R mirror in .ru domain, and they seems to accept

Hi all, I would like to ask that is there any function in R which can solve nonlinear system equations with several variables. Thats mean some functions similar to the 'fsolve' or 'fzero' in matlab. Thanks you Jerry _________________________________________________________________ Get 10Mb extra storage for MSN Hotmail. Subscribe Now!

According David Jame's response to my earlier question, there is a problem with setGeneric.setMethod in R 1.8.0 that affects DBI and RMySQL. Is there a fix for this? David Jame's refers to an 'R-patched version' but I haven't seen anything like this on CRAN. Would going back to an older version of R solve the problem? Thanks, Barnet Wagman "David James wrote:

Hi Folks, I'm contemplating using locator() to digitise external graphics. To set context, I would be using X11 display on Linux. To pre-empt the obvious comment: I've found on the R site the suggestion to use the 'pixmap' package. I've tried this, and it works; but it involves building a big R object (the internal pixmap representation), and this chokes my somewhat puny

Hi, I apologize for not following the posting rules? Here is the text from my previous post: "I started evaluating the 'Peaks' package a couple of months ago and found it to be quite useful. Getting back to it last week I had to set up my R environment due to hardware changes again. The Peaks package loads with no problem. After successfully reinstalling all packages (RedHat

Dear R-Users, I need to find a smooth function f() and coefficients a_i that give the best fit to y ~ a_0 + a_1*f(x_1) + a_2*f(x_2) Note that it is the same non-linear transformation f() that is applied to both x_1 and x_2. So my first question is how can I do it in R? A more general question is this: suppose I have a utility function U(a_i, f()), where f() is say a spline. Is there a general

Hello! Some CS-guys (the type who knows what Church formalism is) keep asking me questions about formal definitions of R-language that I can not answer (or even understand). Is there some freely available papers which I can throw at them where it would be explained is R functional/OOP/procedural language, does it use weak/strong, dynamic/static typization, does it use lazy or ...(do not know

Why this command does not return grob? What is special about grill and what makes it different from axis, lines, rectangles... Thanks in advance

...does not work. Do k<-grid.points(c(0.1,0.2,0.3),c(0.1,0.2,0.3),pch=3,vp=viewport()) (symbol - +). Try to change it grid.edit(k, pch=1) (symbol - open circle). Get filled squares. pch from 0 to 25 produces the same output. pch="x" - works OK. Device - x11(), gtk() (from GtkDevice). R -1.6.1

Hello! There is something wrong with nested viewports in grid package (I have tested it in R-1.8.0, may be it is different in other versions). Here is an simple example of a feature which seems strange to me: x11() rec<-T push.viewport(viewport(xscale=c(-10,10),yscale=c(-10,10),gp=gpar(col="magenta")),recording=rec) #Parent viewport with scales -10:10

Hello! Is it possible to use R time series to identificate a process which is subjected to known input? I.e. I have 2 sequences - one is measurements of black box's state and the second is the "force" by which this black box is driven (which is known too) and I want to fit thist two series with AR-process. The "ar" procedure from stats package expects that the force is

Hello! Is it a bug or something? When I try to draw a grid-graphics on ps output background color is always transparent (with standard plot(...) this is not the case - the background is filled with ps.options()$bg color). What's wrong? Drawing a background grid.rect does not help - there is always small transparent margains along picture frame. Can this be fixed (I use R-2.0.1)?

Dear R devolepers! Wouldn't you change src/main/devPS.c file (patch will follow). Problem is with minus sign in ps output. The original code forces the name /minus to the character number 45 (-). But /minus symbol is not defined in standard Adobe encoding and (even worse) is not defined in most type1 fonts (where the name /hyphen is used instead), in this case you will have an empty

Hello! Don't quite understand how can I delete grobs and simultaneously erase graphic output they produce. I first change grob's "vp" field to null (grid.edit(gr,vp=NULL)) to erase it and then call rm(gr) (as grobs are external pointers I'm not shure what this method actually frees allocated memory). May be there is simpler method? Does garbage collector have any effect
