Hi everyone, I am desperately looking for a method to interpolate strings within an SQL statement as follows: I get a lot of rows out of a database (in my example POSITION_to_ZIPCODE Database with holds records for German ZIP Code <--> Gauss-Krueger Coordinate System ) and want this to be selected and computed individually row by row as follows: library(RODBC) channel <-

Dear Friends, Yesterday I posed a question to the list concerning the possibility of doing animation examples in R. Here is an example S-Plus (4.5 for Windows ) that I wrote to illustrate my problem. If I try this in R (comment out the graphsheet and guilocator calls) I don't see my results until after the function has iterated through the 100 trials. I would like to plot each iteration.

Hello all, Is it possible to change the radii line type in radial plots? I wasn't able to find anything online.

Hello. Is it possible to set specify the font used by legend()? I would like to specify a fixed-width font so that I can line up parts of vertically stacked curve labels. For example, it would be nice if I could align the names, ages, and weights in the following three curve labels: Bob age=7 weight=100 Alexander age=13 weight=150 Susan age=20 weight=130 Is there perhaps a clever

I've wrote some code to simulate a random walk in 2 dimensions on a lattice. Basically I want to add something in to make it plot it point by point so you can see what is going on. Heres my code for the random walk in 2d RW2D<-function(N) { i<-0 xdir<-0 ydir<-0 xpos<-vector() xpos[1]<-xdir ypos<-vector() ypos[1]<-ydir for (i in 1:N-1)

Hi all, these are the remaining unapplied patches of the ARM HDLCD patch series. Changes in v7: - rebased on b61ed421d2c85b5b106c63f2c14f8aa162b282f0; - turn more printk and panic into early_printk and early_panic. Changes in v6: - rebased on 77d3a1db3196b1b5864469f8d3f41d496800c795; - remove useless initializations to NULL in lfb_init; - more compact checks in lfb_init. Changes in v5: - move

Hello, I would like to know more about how to use the "apply" family and have attempted to convert nested "for" loops in example code from Contributed Documentation ("The Friendly Beginners' R Course? by Toby Marthews (ZIP, 2007-03-01)") to an "apply" function(s). The relevant code is: distances=c(51,65,175,196,197,125,10,56) #distances of 8 houses

Hi listers, A few days ago I posted a question about the use of the stars function on selected lines of a frame. Thanks to two helpers, a closer look at the scale argument allowed to partially solve the problem. Yet I still have a problem with stars. Allow me to explain what I intend to do (sorry for my poor English and the long post): I want to graph an activity index of a fish during the day

Hi everyone, I want you all help me to give an idea, how to draw pentagon with points? Maybe can use function, but I'm stuck. Yhank you. -- Hemavathi Ramulu [[alternative HTML version deleted]]

Hi, is there a way to place text at the upper left corner (or another corner) of the plot? I want to place it really at the upper left corner of the whole plot (the file I get), not at the upper left corner of the plot-region. I tried text() and mtext(), and corner.label() of the plotrix package but it didn't work out. thanks!

Does LightDM support multiseat setups? For example, I have a PC with multiple graphics cards, monitors, keyboards - used by multiple users concurrently. Will LightDM let me use one PC by many users concurrently (i.e. login screen on every monitor, allowing to start different sessions for different users). -- Tomasz Chmielewski http://wpkg.org

Hi, I was wondering if someone in the mailing list has any insight into this segfault error that I consistently find when running a script containing heatmap() in R 2.8.1 and 2.8.0 on a Linux 64-bit machine. Some points: 1. This occurs when running heatmap(). 2. Interestingly, if I source() the script or copy and paste the script in its entirety, this error occurs. However, if I run the

I am having some problems with variable scoping. I need to be able to set a variable that is accessable by other methods within the class (or instance) (i.e not global). An example is 2 pages that change a class variable: class AjtestController < ApplicationController def initialize @@variable = "init" end def show @display = @@variable @@variable = "change 1"

> I wanted to simulate the Matlab DISPLAY function for some time now. After seeing a recent proposal by Gabor Grothendieck I came up with the following solution, display <- function(...) { my_names <- lapply(substitute(placeholderFunction(...))[-1], deparse) for (my in my_names) cat(my, "=", eval(parse(text=my)), "\n", sep=" ") } that works about as

Hi, I've been playing with the tcltk package. It's very nice to have access to buttons, menus etc. now. Thank you! Alas, I also have questions: In Tcl everything is a string [*]. This is not the case in R, of course. So why are return values of tk commands still strings? (Is there any other reason than speed or "package is work in progress"?) Example: > tt <-

Hello everybody I'm trying to write a simple version of matlab's "quiver". The idea is that I have fluid with velocity defined on a grid. I have a matrix of x-components of velocity and a matrix of y-components and I want to see the overall flow pattern. (I work with 2D fluid mechanics problems). My first-stab function is below: quiver <- function(u,v,scale=1) # first

Hi I've a problem with the following example: library(tcltk) .Tcl("array unset tclArray") myRarray <- matrix(1:1000, ncol=20) for (i in (0:49)) for (j in (0:19)) .Tcl(paste("set tclArray(",i,",",j,") ",myRarray[i+1,j+1],sep="")) tt<-tktoplevel() table1 <- tkwidget(tt,"table",variable="tclArray",

Hi When I try to update an number in a large data.frame by its pos It's really slow it take almost a sec to do this and I wonder why and if where is any faster way to update a number in a data.frame ive tried DF$col[POS]<-number DF[xPOS,yPOS]<-number Thx //Joel -- View this message in context: http://r.789695.n4.nabble.com/Slow-update-insert-on-Data-frame-tp3055707p3055707.html
