error in Recursive
Hi I need help in the recursive problem. this is my code #Generate two random Numbers minval=20 maxval=100 cutoffValue=50 optVal<- function(cutoffValue,minval,maxval) { x=runif(2) x=x*cutoffValue for( i in 1:2) { if(x[i] < 30 || x[i] >60) # checking it falls between the range { optVal(cutoffValue,minval,maxval) } } return(x) }

objects of class "matrix" and mode "list"?
Hello everyone, I cannot seem to find information about objects of class "matrix" and mode "list", and how to handle them (apart from flattening the list). I get this type of object from using sapply(). Sorry for the long example, but the code below illustrates how I get this type of object. Is anyone aware of documentation regarding this object? Thanks very much, Stephen

R code for selecting places spatially and by time
Hi all The code of trying to write relates to selecting properties (given by x and y co-ordinates) spatially (distance "X" from "infected" properties identified by date) over a certain time period. i.e. what properties are within 3 km from properties infected on "2008-01-01" over the last 14 days. Is any one able to give me some clues on how to write code to solve

Fitting Contour to Data Points
Apologies for the mass mailing today! I am attempting to produce a contour plot for phsical data on a map matrix. I have a small number of data points which each has an (x,y) co-ordinate together with a corresponding value which I would like to cvreate a contour plot for. I have tried the following code: contour(data$x,data$y,data$value) but am told: Error in contour.default(data$x, data$y,

lowess output looks wrong (PR#7891)
Just noticed nobody has commented on this, so I took a look, and I can't see the problem (2.1.0 looks the same as 2.1.1 to me). What is supposed to be wrong?

memory error in for loop
hi, I have been attempting to run this script and am getting some strange results. The script connects to a database and retrieves a series of tables, using sequential sql statements. I have tested all of the sql statements in the PostGreSQL terminal and they all return the desired results. I place each table into a list and run a FOR loop for 'i' in the list. The script generates

Help with coloring segments on a plot
Hi. I need a very short piece of help regarding colouring segments plotted on a graph. When I am plotting segments for the graph, I am using "red" and "darkgreen for the values "1" and "2" respectively. Heres the relevant line of code in R: + col = c("red", "darkgreen")[line.colour.value]) I just need to extend this to refer to a larger

horizontal boxplot + xlim
Hi there, I get a strange behaviour of a boxplot with the following code. There seems to be a problem with the xlim-parameter. Did I do anything wrong? What else can I do to force the boxplot to have a defined x-range? x <- rnorm(100) boxplot(x, notch=TRUE, xlab=parameter, xlim <- c(-4,4), horizontal = TRUE) Antje

strange QQ-Plot
Hi, i am working on a data set with EDA. That includes QQ-Plots of residuals vs expected normal distribution. What puzzles me is that the range of ordinate and abscissae is so different: while the theoretical quantiles range from [-2, 2] the sample quantiles on the ordinate do extent from [-20, 50]. Quite obviously some kind of transformation is done. Although i intensively RTFM i could not

plot representation of calculated value known to be 7.4
Thanks a lot - formatting the ordinate as ylim=c(4,10) before plotting pH also removed the problem, and options(digits=10) confirmed that pH was not all exactly 7.4 - as I knew. Still I wonder just why R chooses to plot(ATOT,pH) as shown with repeated "7.4" instead of some more detailed representation. Thanks a gain and happy New Year!

Loess over split data
Dear R users, I am having trouble devising an efficient way to run a loess() function on all columns of a data.frame (with the x factor remaining the same for all columns) and I was hoping that someone here could help me fix my code so that I won't have to resort to using a for loop. (You'll find the upcoming lines of code in a single block near the end of the message.) Here's a

Level Plot and Scale of Colorkey
I am drawing level plots but I would like to specify the range of the colorkey, I am not having any success figuring this out so any help would be greatly appreciated!

Inputting Co-ordinates
Hello I am trying to input some co-ordinate sets into R of the form x,y by using lists. The command I am using is: p1 <- list(x=c(3445,563,646), y=c(234,567,456)) However the actual co-ordinate sets that I am trying to input have 305 points each and I think that the program will not accept a command that is as long as necessary. Is this so? If this is the case can you tell me how to read

gcc 2.95.2/irix/Laguerre_With_Deflation/inifinte loop
I built ogg vorbis from the rc1 cvs source on Irix 6.5.12 with gcc 2.95.2. Using oggenc I encoded about 8,000 aiff files but found about a dozen where oggenc would go into an infinite loop. I tracked the problem with Laguerre_With_Deflation() as far back as logmask being Inf in floor0_forward. I'm now building gcc 3.0 with the expectation this is a compiler issue. If not, I'll back

How to increase precision to handle very low P-values
Hello, Rlisters I have to compute p-values that are on the tail of the distribution, P-values < 10^-20. However, my current implementations enable one to estimate P-values up to 10^-12, or so. A typical example is found below, where t is my critical value. ########### example - code adapted from Rassoc ####################### rho01 = 0.5 rho105 = 0.5 rho005 = 0.5 t = 8 z = 2
