im trying to write a for loop so that every leap year, the number of days becomes to 366 instead of 365. could someone help me out? and also, this set of data has 99.99s I set all the 99.99 ==NA. however, when im doing the order function to find the max value of that year, it still reads 99.99 as the max value. Thank you very much maxday <- matrix(NA,63,5) for (a in 1948:2010){

In conducting studies of animal orientation and displacement, I need to produce circular histograms of angles (bearings in radians 0-2pi) where the centre of the circle indicates very few observations for a given bin of angles and outwardly concentric circles indicate greater frequencies of observations for a given bin of angles. I'd like not to have to write the function myself but I

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 =

Dear R experts, I am plotting the population of students who live in a city, and in successive circular bands made of the contiguous districts that surround the city. This is a stylized figure, where I specify the area of each successive circle based on the cumulative population of students. I want to compare two sets of concentric circles across different populations - such as 'All

Hello everyone, I'm stumped. I'd like to create a scatterplot matrix with circular reference lines. Here is an example in 2d: library(ellipse) set.seed(1) dat <- matrix(rnorm(300), ncol = 3) colnames(dat) <- c("X1", "X2", "X3") dat <- as.data.frame(dat) grps <- factor(rep(letters[1:4], 25)) panel.circ <- function(x, y, ...) { circ1

I have an issue with a circular package dependence that prevents building/checking, and I seek advice on breaking the circle so the packages can pass the build-check tests that are required for CRAN submission. The package pair I'm working with is slow to build, but my tests suggest the issue may be general, and so I will explain it in general terms. Suppose there are two packages: 1. Foo,

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

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

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)

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

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

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.

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

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

Hi All, Does anyone know how to compare the means of several circular-data samplings? Any related websites, references and softwares? Thanks Xiaohua -- Xiaohua Dai, Dr. [[alternative HTML version deleted]]

So I decided to bundle up the small amount of work I've done on generating source-level debugging info into a DebugInfoBuilder class like I described earlier. I went and added a new file to the "Support" directory (in include and lib). However, when I try to compile it, it complains of a circular dependency error between libCore and libSupport: find-cycles.pl: Circular

Hello, I ran into an interesting problem earlier today. I have a Unix machine I maintain in a largely Windows shop. They use Windows Backup for their backups, and so I created a readonly share of the entire filesystem with one user, "backup", who is an admin user. This lets them back up the entire Unix machine by attaching to the "backup" share, but nothing can be changed.

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 all, I'm new to the list here, and I have what I think is a simple question. Using the "circular" package, is there a way to plot the mean and variance on top of a rose diagram or other plot of the data?
