Hello, I'm using lattice and opened an X11 device with the following call X11(width=5,height=5,pointsize=1) I then ran the following code library(lattice) x<-rnorm(30,sd=2) y<-runif(30) xyplot(y~x,pch=".",col="black",cex=1) If i remove "cex=1", not all the points are plotted. From ?X11, i read,"pch='.' with cex=1 corresponds to a

Hello, The following code produces a quadrilateral: q<-matrix(c(1,3,1,2,3,1,2,4,2,1,4,2),nrow=4,byrow=T) qc<-xyz.coords(q) wireframe(z~y*x,qc) I have 2 questions 1) How can i remove the bounding box i.e the cube encompassing the quadrilateral? 2) Is there any function to get the 2D coordinates of the quadrilateral actually used in the final plot ? I could manually

Hi, After a few modifications in the makefiles, I successfully compiled the Qt device (written by Deepayan Sirkar) for OS X 10.4.9 on a Powerbook. However when loading into R If i remove this line from zzz.R in qtutils/R grDevices::deviceIsInteractive("QT") and then install >library(qtutils) loads fine and the QT() calls returns a QT window, however, if i switch to

Hi, I need to integrate a 2D function over range where the limits depend on the other e.g integrate f(x,y)=x*y over {x,0,1} and {y,x,1}. i.e \int_0^1 \int_x^1 xy dydx I checked adapt but it doesn't seem to help here. Are they any packages for this sort of thing? I tried RSitesearch but couldn't find the answer to this. Many thanks for you help. Regards Saptarshi Saptarshi Guha

Hi, I have another question. Is there any command that waits for key input? I am running R on OS X, so getGraphicsEvents doesn't work. I have put some debug print messages in a function and would like to pause the code every time the message is printed and continue on a keypress.

Hello, How can i 'fix' the following output. v=viewport(x=216/2, y=216/2,w=216, h=216,default.units = "bigpts") pushViewport(v) x=c(119,130,140,151) y=c(124,124,124,124) grid.points(x,y,size=unit(1,"bigpts"),default.units="bigpts",pch=".") grid.points(x-2,y,size=unit(1,"bigpts"),default.units="bigpts",pch=".")

Hello, I have some code which generates lattice objects. The function recieves serialized forms of the lattice objects which it then unserializes and then adds to an ArrayList<REXP>. REXPRaw rser = new REXPRaw( target ); //target contains the raw serialized forms of lattice objects rconn.assign("temp",rser); REXP ret =

Hello, Having installed R 2.3 for OS X Tiger 10.4.6(PPC), i tried running the new R.app, but it hangs (spinning beachball). Moreover, i can't install the RGUI from within the R-2.3 DMG, - it tells me i must have R 10.4 installed ! (I have 10.4.6) R 2.3 runs successfully from the command line however. I tried compiling from sources, but Xcode has this error(i.e it can't locate

Hi, I am writing an R package with two functions in C++. So far everything works. Now, i would like to write a third function which would use a pointer (it is a pointer to a class object) created by first function. I tried placing this pointer outside of the function definitions (i.e to make it global) but when called in the 3rd function i get > *** caught bus error *** address 0x0,

Hello, It is possible to set the aspect ratio of the Y-axis to the X-axis in xyplot (a) xyplot(y~x,aspect=1.8) Suppose I have only 1 panel and i wish to set the length of the X- axis to 2" keeping the same aspect ratio as in (a). I would also like to keep the same scales. I suppose i need to do something in prepanel but what? Is there any function i can call to set the actual

Hi, I am writing a package which requires the ANN(Approx N.Neighbors) library (found here http://www.cs.umd.edu/~mount/ANN/). My package directory looks something like this atry/ atry/src/ann/ <--ann source is here atry/src/ann/include atry/src/ann/lib <--ann lib file is here atry/src/disp.cpp < my file which requires the ann lib The last file disp.cpp has the include line

Hello, I have a multi-page display each consisting of two-panels above each other. I need to draw a line from the top panel to bottom panel. Using current.vpTree() i find that "plot1.panel.1.2.vp" and "plot1.panel.1.1.vp" are the top and bottom ones respectively. I am using the following code(inspired by Paul Murrell's R Graphics) to draw a line. (All the

Hello, I was trying this bit of code (i know it is an extreme case) g=function(r){ if(r==1) return(list(x=1)) else return(list(x=g(r-1))) } For z=g(500), the code runs but when I print z i.e >> z I get <environment: R_GlobalEnv> *** caught bus error *** address 0x1, cause 'non-existent physical address' Possible actions: 1: abort (with core dump, if enabled)

Hello, I have to write single Long to a server written in java. The server passes the input as in.readLong() // it expects to receive 8 bytes In Python, i can do it by sending struct.pack( "!q", value) However, I have tried this writeBin(length(x),con=conn,endian="big") #conn opened in binary But the response on the server side is wrong, eg. 1 is received as

Hello, My plots consist of 2 rows, 1 column, many pages I've managed to selectively turn of strips for the bottom panel and roll my own strip for the top par.strip.text = list(lines = c(0,3),cex=0.6) I have my own custom prepanel function too. What i'd like to do is turn off the x-axis for the top panel (since on a given page the xlim is same for both top and bottom panel, but the

I'm using lattice 0.14. As of version 0.5 the Changes says there is a global list called 'lattice.theme'. How can I access this? I have tried many ways, including options(lattice.theme) lattice.getOption("lattice.theme") get("lattice.theme", envir = .LatticeEnv) getFromNamespace("lattice.theme", "lattice")

Hello, I call a function via .Call passing to it a raw vector(D) and an integer(I) The vector is a series K1,KData1, V1,VData1, K2, KData2, ... where the integer K1 is the length of Data1 and similarly for Ki (wrt Datai)(similarly for V*) There 2*I such pairs( (Ki,KDatai), (Vi,VDatai)) The numbers Ki(and Vi) are written in network order. I am returning a list of I elements each element a

I upgraded to R-2.2.1 on two PPC G5 computers today. Further I want to work with the tseries package for the first time.

Hello, I have a stripplot with 200+ labels i.e i have network connections. The y-axis are the server port numbers and am graphing the number of packets in a connection. Roughly stripplot(totpacks~portnum,data=network) Due to the large number of server ports in my dataset, the y-axis labels overlap so I would like to split it across several panels(1 panel per page) with about 25-50 per
