similar to: Sv: Using locator() to digitise

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

OK, I just took my first non-root user live on my Samba 3.0.7 system. Printing is via cups, with drivers stored in the print$ share. This user is a local power user. She can add printers, or root can add them. Root can also print from them. If this user tries to print anything (a test page even) she gets a non-verbose error that looks like a permissions error. She can view the queues

Hello all, I upgraded from R 1.8.1 to 1.9.0 (Windows XP), and spotted an odd thing. The last three letters in the Swedish alphabet are ??, ?? and ??. (In case they don't show correctly: they are a with a ring, a with two dots, and o with two dots (HTML: å ä ö). When I use these as variable names in a data.frame, odd things happen: In R 1.8.1, ?? (å)

Dear list, I would like to simulate individual survival times from a model that has been fitted using the survreg procedure (library survival). Output shown below. My plan is to extract the shape and scale arguments for use with rweibull() since my error terms are assumed to be Weibull, but it does not make any sense. The mean survival time is easy to predict, but I would like to simulate

Full_Name: James Michael Rath Version: all (I think) OS: doesn't matter Submission from: (NULL) (129.116.226.162) The code for pnorm in R was adapted from a Fortran library published in the ACM TOMS journal. The published version had a typographical error, though, which was pointed out in a second article published three years after the original. The error was that a macro/variable named

Is it possible to fill the boxes of a boxplot with filling patterns/texture instead of colours? Or both mixed? (for example white, grey, left diagonal striped, right diagonal striped) How can I do that? I searched here, but didn't find an answer. Thank you! -- View this message in context: http://r.789695.n4.nabble.com/Fill-pattern-for-Boxplots-tp4639698.html Sent from the R help mailing

Summary: The locale setting in the operating system seems to be involved in what confused me a little bit. Thank you all for your help, especially the suggested work-around data.frame(..., check.names=F) which works very well. A mystery still to be solved is why two versions of R, running on the same machine on the same time, behaves differently. Please do not respond to this on the list. I

Dear list members, This is a question is about building an R package under windows and cygwin. Please bear with me. I have a package in R that compiles well on my stationary computer (WINDOWS NT, R 1.8.1 and prior), and the resulting (package_version).zip file works well there. It contains an R script file and a C file. After installing tools to build the package on my laptop, the package

We have a HP Design Jet 650C Plotter which is hooked to the net via a jetdirect nic. Now I dont have a clue on how to use this plotter over the net. It doesent show up in the network neighborhood and I cant find anything about jetdirect plotters in the Linux documentation or the inet. The server is running Suse Linux 6.2 and Samba 2.05a. TIA Florian v. Behr

I am trying to use the angle option in polygon to create polygons filled with horizontal and vertical lines. The polygons I am crating are irregular and it the angle function appears to set the angle of the shading perpendicular to the polygon sides rather than perpendicular to the axes. Is there any way to set the angle relative to the axes rather than relative to the polygon sides?

Filling polygons with lines is a throwback to the time when the height of quality graphics was the mechanical pen plotter (a device that used a pen in a mechanical arm to draw the plot on a piece of paper). Computing and printing technology has advanced quite a bit from that day, so you may want to reconsider why you want polygons filled with lines instead of just a solid color (and I consider

In "An Introduction to R" (See R help menu), there is an example of a function 'open.account' that makes use of the lexical scope in R. I have a set of functions that can be used to output R tables and graphics into a single report document. (I am aware that several tools can do this already). While reorganizing my code, I realize that I can collect my functions in a list, in

Hello, I'm trying to create a vector of r^2 values for using a function which I will run in a "for" loop. Example: per<-rnorm(100,.5,.2)^2 x<-rnorm(100,10,5) y<-rnorm(100,20,5) fr<-data.frame(x,y,per) test<-rep(0,9) plotter<-function(i){ temp.i<-fr[fr$per <=(i*.10),] with(temp.i, plot(x, y, main=(i*.10),)) mod<-lm(y~x-1,data=temp.i)

G'day All, We are using Samba 3.0.6 as a PDC and print server. The OS is RHEL 3.0. I've gone thru the procedure detailed in "The Official Samba Howto..." book and the other HP and Lexmark LaserJet printers work properly using the postscript drivers. However, HP 1055CM Color Plotter works best with the HPGL/2 drivers if the drivers are installed on the client workstation but, do

Hi everyone! Could you please help me with the following assignment? My aim is to write a custom function that draws the plots of functions submitted by the user. The catch is, that we do not know the exact number of functions the user will select to draw. The program is relatively easy with one function, f.e sin: mf<- function(f,range,quality){ x<- seq(range[1],range[2],

Hello, I have a bunch of Windows XP Pro machines, Samba 2.2.4, and several plotters on Jetdirect cards, and several printers on Netport 10/100 Muli-port network print servers. I have successfully configured Samba 2.2.4 to allow Windows XP to join the domain controlled by Samba and automaticaly create its own computer account on Samba. I would now like to setup Samba to share all the printers

Another question on functions - I have something that looks like plotter<-function(i){ temp.i<-rwb[rwb$vector1 <=(i*.10),] with(temp.i, plot(vector2, vector3, main=(i*.10),)) mod<-lm(vector3~vector3-1,data=temp.i) r2<-summary(mod)$adj.r.squared rsqrd[i]<-r2 legend("bottomright", legend=signif(r2), col="black") abline(mod) rsqrd<<-rsqrd } I'd

The angle is not based on the polygon edges, but it can seem that way if you do not use the asp=1 argument in your plot. Try this example, > plot(1:10, 1:10, type='n') > x <- c(1, 3, 5, 3) > y <- c(3, 5, 3, 1) > polygon(x, y, angle=0, density=10) > polygon(x, y + 4.5, angle=45, density=10) > polygon(x + 4.5, y + 4.5, angle=90, density=10) > polygon(x + 4.5, y,

Hello, I have trouble converting a character string to a R object. Let me describe this by an example; > dim(a) [1] 270 14 > dim("a") NULL > names(a) [1] "Var1" "Var2" "Var3" "Var4" "Var5" "Var6" "Var7" "Var8" "Var9" [10] "Var10" "Var11" "Var12"
