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.circula...

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 circular package work for me...

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...

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 Lo...

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, F...

...ber, 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 referred to as bullseye displays in the nuclear medicine literature. Does any reader of these messages know of a R function/package that offers this functionality? Also I noticed that in some contexts you can define a "circular" attribute for your dat...

I have a suggestion for kernapply for ts objects. When we choose the option circular=F, the returned series don't have the correct dates. The removed dates are all at the beginning instead of half at the beginning and half at the end. It is particularly useful when we need to smooth the series (or remove a trend using a filter) before estimating a model (like in macroeconom...

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 Charlott...

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, Ti...

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.

Hi, If I have two sets of directional data (in radians) and want to compare them with a multifactorial anova. Is it even legitimate to compare circular data with an anova? The books I've picked up from the library don't really say, but it looks unlikely. If it is allowable, is my having stored the data as circular (X = as.circular(A)) something the aov() function will take into account, assuming the anova would be somewhat different for d...

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 = 'light...

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 b...

...f looks like 12,12,4,5,6,5,11,10,3,9,9,9,12,12,2 total of 15 numbers. I'm trying to add all the same numbers, such that, there are 4 of 12s,1 of 11, 1 of 10, 3 of 9s, and such.... so the circle plot would have 4 parts of 12, 1 part of 11, 1 part of 10, 3 part of 9, and such... I tried >plot(circular(maxday[,2]*2*pi/12)) ##where maxday[,2] looks like the data above. but the only thing came out was dots, and they over wrote on each other. basically I would like to plot a pizza shape circle, where some of the slices are bigger than others. Thank you very much. [[alternative HTML version delete...

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 pa...

Hi, I am far from experienced in both R and time series hence the question. The code for spec.pgram() seems to involve a circularity of the kernel (see below) yielding new power estimates to all frequencies computed by FFT. " if (!is.null(kernel)) { for (i in 1:ncol(x)) for (j in 1:ncol(x)) pgram[, i, j] <- kernapply(pgram[, i, j], kernel, circular = TRUE) " Can anyone comment on whethe...

...files on the system, "/etc", "/home", and "/usr/local". We started running the backup, and it first estimated 3GB, which is about right. As it ran, though, it kept increasing its estimate; we stopped it at about 20GB. Closer inspection showed that it was confused by circular links to directories. The default Apache configuration on our system has a circular link, with "/etc/apache/conf" -> "/etc/apache". I believe this is for compatibility, since Apache configuration files used to be in "/etc/apache/conf", but that's beside the po...

...cided 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 dependency between *.a files: find-cycles.pl: libLLVMCore.a libLLVMSupport.a The odd part is, that no other file in LLVM even references my header, so I'm not sure where the cycle is. The headers that I am i...

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 input data (dir, mag) are cha...
