I try to find a circular filter that I can export to be used in a spatial software. Assuming, we have a matrix, representing 9x9 regularly spaced points with the center point 'filter[5, 5]'. In this example, I want to find a function that weighs all neighbor points within a distance of d=4 units with 1: > filter <- matrix(0, 9, 9) > filter <- function() ... > filter

I want to get the minimum arc (in degrees) needed to include a set of compass directions. I would like to use the range.circular() function of the package circular, because that package understands a compass-type of angle convention, but it gives results I don't understand. Howver, I can get the correct answer in the example below, 90 degrees, using the CircStats package. How can I make the

I would like to use aggregate.ts() and apply() on circular data, but I can't figure out how to get the circular data components to pass through: library(circular) x <- circular(c(20, 30, 355, 5, 345, 25), units = "degrees") % I want to get the mean angle for each successive pair; answer should be c(25, 0, 5): aggregate.ts(x, ndeltat=2, FUN="mean.circular") Error in

Hi, I installed "circular" package and I wanted to load it automatically when R starts up, so I added the following lines in file Rprofile.site, .First <- function() library(circular) When R starts up, it gives me the following error: ---------- Loading required package: boot Loading required package: graphics Loading required package: stats Error : .onAttach failed in

I have started using the circular package but it is not recognizing the function arrows.circular. I attempted to use the example provided in the circular manual. Here is the example code using the circular package: plot(rvonmises(10, circular(0), kappa=1)) arrows.circular(rvonmises(10, circular(0), kappa=1)) arrows.circular(rvonmises(10, circular(0), kappa=1), y=runif(10), col=2)

Dear all, I am using plot.circular(x, stack=TRUE) to plot a "histogram" from a list of angle. I would also like to draw a line from the origin at the angle of the mean (mean.circular), preferably with the resultant's length (rho.circular) as length. How do I achieve this on the circular plot, please? Thanks a lot, Tim -- -- Tim Gruene Institut fuer anorganische Chemie

Dear r-helpers, I want to show that time is flowing CCW in the following: require(circular) len <- 8 labl <- as.character(c(0, 1, 1, 1, 0, 0, 1, 0)) r <- circular(2*pi* (rep(c(1, 3, 6), each = 200)/len + rnorm(600, 0, 0.025))) r.dens <- density(r, bw = 25, adjust = 4, kernel = 'vonmises') plot(r, shrink = 2.5, axes = FALSE, ticks = FALSE, pch = 1, col =

I recently got a scary-looking circular dependency as a puppet error, and it took some thought to decipher it. Long story short, I fed it to graphviz, and the graph made it obvious where the problem was. Thought I''d share, in case others are having the same trouble. Code''s at http://gist.github.com/74566, and also pasted below for convenience. -- Philip # Make sense of

Hello Friends!!! I would want draw a circular histogram, and I would like draw a polygon with a circular side. This is easy if I use the functions polygon and arc, but I want that the polygon with a circular side have background colour. The polygon created with function polygon can have background colour, but the surface created with function arc can?t have background colour. How I could create a

Hi, I am looking for a way to analyze a dataset with a circular dependent variable and three independent factors. To be specific, the circular variable comprises of arrival times of pollinators to flowers. The independent variables are pollinator species, flower sex and locality. I have failed to find a way how to include all three factors. The "circular" package seems to enable testing

require(circular) c <- circular(rep(0, 20), zero = pi/2, rotation = 'clock') plot(c, stack = TRUE, shrink = 1.5) Can anyone tell me why the stack is offset from 0? _____________________________ Professor Michael Kubovy University of Virginia Department of Psychology USPS: P.O.Box 400400 Charlottesville, VA 22904-4400 Parcels: Room 102 Gilmer Hall McCormick

I have data for several rings of a left heart chamber, and which I would like to display in concentric rings, with color-encoding of the values. Each ring corresponds to one slice through the heart, and the rings correspond to positions from the base to the apex of the heart as you move from the outermost ring to the innermost one. The data have a circular pattern. These types of displays are

Dear R-users, As noted by Paul Murrell < p.murrell at auckland.ac.nz > there is errors in the code for polar plotting I send to R-help under the title "Polar plot, circular plot (angular data)" at Thu Oct 17 2002 - 12:18:20 CEST. Thanks! I have reorganized the code into a structure ('pp'). This allows plots to be modified to a greater extent by passing arguments by ...

Full_Name: Allyson Williams Version: 2.1.1 OS: Windows XP Submission from: (NULL) (203.25.1.208) I'm using the 'Circular' package to plot windroses. I think the output table (see out2$table below) is incorrect when using different rotations. More precisely, when a rotation is used for the plot, the output table stuffs up. This example is from the code in the help notes, although the

Hi R-profs, Maybe my question is a little off topic. Could any one tell me how to calculate a linear-circular correlation coefficient and its p-values? I had a quick look at circular and CircStats packages and did not find the related function. Thanks for any kindly help.

In that scenario, I would expect that QCA would suggest Venn and Venn would suggest QCA. Then there's no circular dependency problem.

Hi, I have a variable (current speed direction) which is circular (0=360 degrees), and I'd like my GLM to include the variable as a circular variable. Can I do this? And what is the code? I'm actually doing a GLM-GEE using the 'geepack' package, so want to use it in that, but also interested in whether it can also be used in GLMs and GAMs (I use the 'mgcv' package for

Hi, I'm using the cluster library to examine multivariate data. The data come from a connection to a postgres database, and I did a short R script to do the analisys. With the cluster version included in R1.8.0, daisy worked well for my data, but now, when I call daisy, I obtain the following messages: --------- Error in if (any(sx == 0)) { : missing value where TRUE/FALSE needed In
