similar to: executing loop in circular way

Dear All, I am trying to define a loop for a m*n matrix, where i=1:n and j=1:m. Unlike the usual for loop, i should go in the following way: For j=1, i=1,2,3,....n For j=2, i=n,n-1,n-2,......,1 For j=3, i=1,2,3,.....n etc. which means i should go in either increasing or decreasing order alternatively. Can anyone please help me in doing this? Thanks, Cassie [[alternative HTML version

Dear all, I created a n*2 matrix and I want to replace the ith row with a vector. Can anyone suggest me what is the simple way to do it? Sorry for bothering you with such simple question. I appreciate any hints or advice. Thanks in advance. Cassie [[alternative HTML version deleted]]

Dear all, I am trying to simulate from truncated Pareto distribution. I know there is a package called PtProcess for Pareto distribution...but it is not for truncated one. Can anyone please help me with this? Thanks in advance. Cassie [[alternative HTML version deleted]]

Dear all, I am trying to simulate from discrete uniform distribution. But I could not find any in-built code in R. Could anyone help me please? Thanks in advance for the time and help. Cassie [[alternative HTML version deleted]]

Hello everyone, I am wondering if there is any routine in R which can convert time given in 'seconds' unit to the 12 hour time format. For example, suppose the data set looks like x=c(36885,84000,20) #x in seconds I want to get the output as [1] " 11:14:45 AM" [2] " 11:20:00 PM" [3] "12:20:00 AM" Does anyone have any idea? Thanks in advance. Cassie

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 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)

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

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

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

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-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 =

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.

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

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

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

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.

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

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
