Multidimensional Integration over arbitrary sets
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

Waiting for Key input
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. Thank you Saptarshi Saptarshi Guha | sapsi@pobox.com | http://www.stat.purdue.edu/~sguha

A question regarding cex and pch="." in lattice
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

Question regarding QT device
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

Substituting functions in package - Lattice
Hi, I'm trying to learn how a package works but substituting a parituclart function with my own (basically the original one with some debug statements). The package is lattice and the method is "print.trellis" which is a S3 method and is not visible. To replace this, i sourced a file with the rewritten print.trellis, and the old one was replaced. However, i get this error

A question on grid - grid.points not spaced properly
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=".")

How to preserve data across function calls in a library package
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,

A question regarding Wireframe in Package Lattice
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

ANN: rproto v1 (Protocol Buffers and R)
Hello, I apologize if this is not the list for package announcements. Having said that I've released a package called rprotos which implements a simple serialization using Googles protocol buffers[1]. The package also includes some miscellaneous functions for writing/ reading variable length encoded integers, and Base64 encoding/decoding related functions. The package can be downloaded

Lines between panels in lattice
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

Rserve and creating a list of lists
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>.

Writing a Long across the network?
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

Lattice and Axis height
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

Splitting a lattice stripplot across several pages
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
