Hi, I have two problem with a for looping using R Version 2.1.1 (2005-06-20) on a Debian Linux Testing. The first problem: warnings messages Look: > xcoord <- 5 > ycoord <- 5 > indice <- 1 > for(i in c(1:5)) {indice <- indice+1;xcoord[indice] <- xcoord+i; ycoord[indice] <- ycoord } Warning messages: 1: number of items to replace is not a multiple of replacement

Dear list, I am trying to program semi-random movement within a circle, with no particles leaving the circle. I would like them to bounce back when they come to close to the wall, but I don't seem to be able to get this right. Would somebody kindly give me a hint ? This is my code so far, the particle starts at some point and moves towards the wall, but I don't get the "bouncing

Hello R Community, I have imported a dataset which contain X Y coordinates and would like to recreate a shape file after some data analysis. What i have done is to import some taxlot data and join them based on some criteria. I want to check to see how well the joining went by reviewing the results in GIS. A couple things. I cant seem to import a shape file correctly using the maptools

Hello again, First I want to thank all the people who answered my question about line width in graphs. I promise I will learn the 'par' help page by heart for the end of the month ! I now want to trace some ellipses to emphasize groups of data. I found how to trace circles with 'symbols()', but no ellipse. I'm planning on writing my own function based on

Hello, I've a problem for setting graphical parameters in perspective plot (function persp). I wonder if it's possible to add some text (function text) on an existing persp plot USING the axis coordinates. In fact I want to add some text on a persp plot according to x coordinates. I've tried to use text(xcoord,ycoord, label="toto") but the toto text doesn't appear at

I am working on creating an R package for doing fire department analysis and am trying to create a function that can display emergency incident densities. The following code sort of does the trick, but I need a display that shows the number of incidents per square mile. I believe the code below shows incidents per square unit (in this case, degrees lat/long). To solve this problem, I believe

I want to do kernel smoothing on the standardised mortality rates at specified location(x-y coordinates) and be able to produce contour map. I've tried to use the package called fields in R (function smooth.2d) but the problem is I get negative results after smoothing and I do not understand why? Your contributions will be highly appreciated or if there is any package that can do this I

I have been working on the following code but keep getting an err message. My current thinking is that the problem is on the indexing but do not know how to fix it. Any help please? ungulate <- read.csv("Ungulate.csv",row.names=1) ungulate <- as.matrix(ungulate);colnames(ungulate)<-NULL;rownames(ungulate)<-NULL habitat <- read.csv("Ungulate_vegetation.csv")

Hi, I'm working on the codes below however every time I run them when they get to OpenBUGS I keep getting the error message: array index is greater than array upper bound for hab.

All, I have three columns of data: id, date, hab. I am trying to set up a matrix that has the id as the rows, date as columns, and the hab value as the data values. Each id/date combination can only have one hab value. I would like for it to look something like this" date 1, date 2, date 3. id 0001 2 1 2 0002 3 5 6 I don't know how to set

Dear R-users: How does one calculate in R the odds ratios for a CATEGORICAL predictor variable that has 4 levels. I see r-help inquiries regarding odds ratios for what looked like a continuous predictor variable. I was wondering how to get the pairwise odds ratios for comparisons of levels of a categorical predictor variable. I can't seem to get the correct output using: >

Hi all, I am new to R, hence this question. I have a set of points with X and Y coordinates. I would like to build an R code to calculate the distances of points within a specified neighborhood (circular range) for each point. I would like the code to be a function, so that I can call the function, specifying parameters (data file, distance), from another piece of code. Also, I would like the

Hello, I am having trouble creating a (1000,3,201) array in R from a data set created within the same script. My problem is that I want to take a matrix that is 1000x603 (called "landmat") and separate this into 201 separate (1000x3) matrices. My problem is when I try to do particular combinations of the columns. I want to take the first 3 columns of "landmat" and create

###Dear R users ###I have been using SensoMineR package from CRAN for most of my work in sensory data analysis and from my usage experience, I encountered some areas for improvement and considered ###modifying the function in SensoMineR package for my personal use.

I'm having an odd problem with strsplit (well I think it's strplit that's causing the problem). When I run the code below as follows: str(parseFormulaMin(y +x +d ~ b +d +e| a * b)) I expect to get List of 3 $ y: chr "y+x+d" $ x: chr "b+d+e" $ g: chr "a*b" But about half the time I get List of 3 $ y: chr "y+x+d" $ x: chr
