similar to: panel/prepanel for polar plots ala xYplot

I?m preparing a package (fastR) for submission to CRAN, but the vignette index keeps going AWOL, or at least R CMD check ?as-cran thinks so. I?ve tried several things and gave myself the weekend to think of other things, but I can?t figure it out. Perhaps someone on the list can lend a hand. Here?s one example situation, where I build the index.html file myself and put it in inst/doc/index.html

I see that the sigma() function has recently been introduced into R 3.3. The help for sigma() says: Extract the estimated standard deviation of the errors, the ?residual standard deviation? (misnomed also ?residual standard error?, e.g., in summary.lm()'s output, from a fitted model. Is there any reason not to fix the mis-naming of residual standard error now too? Both functions are in the

I'd like to create a polar plot similar to those created by the polarFreq function in the openair package. However, this package seems to be specific to wind speed and direction, and requires a "ws" (wind speed) and a "wd" (wind direction) column. My data is unrelated to wind speed, but I'd like to be able to get a plot that does what polarFreq's plots do; I'd

Hi, I just updated to R-2.1.1 and updated packages acordingly However, after the update, routines that use polar.plot did not function as correctly. In plotrix 1.3.3 the polar.plot function does scale label.pos to radians prior to calling radial.plot Hence, the command polar.plot(c(5,10,5,0),c(-10,0,10,20),rp.type='P',

Hi, Two questions: 1 - Say I have average speed and directions for tide and I would like to plot them on a polar plot, but with different colors so I can indicate the two directions. I'm using polar.plot from the plotrix library. How can I add a second "b" and "dir.b" series to a polar.plot? library(plotrix) a = 3 dir.a = 85 b = 4 dir.b = 250 polar.plot(a, dir.a, start =

Dear R-users, my present problem is related to lattice. I would like to put some text in each panel, namely a p-value. I therefore wrote a simple panel function as reported here below. I'm able to write the value in each panel at the maximum value of y for each panel, but this obviously overlay the text to the points. What I'm looking for is to write the text always in the same

I am trying to draw a polar plot, which is easy enough to do in the plotrix package through the polar.plot function. However I would like to change the origin of the length vector. For instance all my length values are between 75 and 85, so instead of having the origin as 0 (the default) I'd like it to be, say, 50. Is there any way do to this in the polar.plot function, or if not is there an

Hi, I'd like to plot in in polar coordinates a line which is given as a vector of lengths and angles. library("plotrix")

In the examples below, the first loses the name attached by foo(), the second retains names attached by bar(). Is this an intentional difference? I?d prefer that the names be retained in both cases. foo <- function(x) { c(mean = base::mean(x)) } bar <- function(x) { c(mean = base::mean(x), sd = stats::sd(x))} aggregate(iris$Sepal.Length, by = list(iris$Species), FUN = foo) #>

Dear all: I'm enjoying using rgl and I want to set a specific viewpoint. I understand that view3d() will do so by setting the 3d polar coordinate angles, theta and phi. In standard polar coordinates, theta is the angle away from the X axis in the X-Y plane and phi (inclination angle) is the angle between the Z axis and the radius vector It appears that when you use view3d() theta is

Greetings to you all. I have two datasets - Time and magnitude. For a particular location, the magnitude of the parameter varies with time. I wish to obtain a polar coordinate distribution of time (0-24h) and magnitudes so as to visualize how magnitude varies with different times of the day (e.g., morning, midnight hours). I have searched for "polar coordinates in R" but could not get

Hello, I am using the polar.plot function from plotrix. Is there a way to change the width of the grid lines? grid.lwd doesn't work....

Hello, I have data for contour plot which is given in polar coordinates. Is there a straightforward way to plot in polar coordinates in R, or do i need to fiddle with transformations and then to sort the x and y vectors to be in ascending order as required by contour function and relatives? Cheers, Todor

I read this story and thought of Allison's prompt to "try not to think about blue eyed polar bears". Will she be banned from foreign travel now? Steve Prior -- snip -- WASHINGTON (Reuters) - Polar bears, sea ice and global warming are taboo subjects, at least in public, for some U.S. scientists attending meetings abroad, environmental groups and a top federal wildlife official

Hi Folks, Here is my attempt at a simple polar plot. > pos <- seq(0,360,by=5) > tspk <- rep(c(1,0,1),c(13,47,13)) > require(plotrix) > polar.plot(tspk,pos,rp.type="s",point.symbols=17,point.col="green4") I only see half the symbols, the other half of each symbol is hidden under the circular grid. In fact if I change rp.type="r", I see the

Hello all- I would like to orient my polar.plot (from package plotrix) so that the circular scale runs clockwise and the origin (ie. 0 degrees) starts at the top of the plot. The defaults of running the scale counter-clockwise and beginning with 90 degrees at the top of the graph seems counter-intuitive to me. I'm using R 2.5.0, and plotrix version 2.2-4. Many thanks, Tim

I have been trying to visualize times of lowest tides, month by month. I have tide predictions with times either in unix time or a text format, and heights in feet or meters. I had been able to derive the clock times of each prediction. I would now like to graph this data with points showing heights as "r" and times as "theta", from 0000 to 2355. There is a seasonal

Hi, I try to compute circular means for a matrix with NAs, but the function "circ.mean" return only means for lines with complete values and do not accept "na.omit=T" or "na.rm=T", or "na.action=na.omit", or "na.fail=T". Also, I try to use "polar.plot" of the package poltrix with the same matrix, but angles are not display because of

Hello, I wanted to find out more about square polar mapping, cause that whole stuff is a bit tricky - to me - and not so easy to understand. Searching the web did't get me any results, so I wonder what the background of square polar mapping is. Is it derived from some mathematical publications or just the result of a brilliant intuition of a Vorbis programmer ? ;) Thanks. Stoffke

Hello, I've read http://xiph.org/ogg/vorbis/doc/stereo.html and the Vorbis specs, but I haven't got a clear concept of how does the Square Polar Mapping works. I mean, in the "Ogg Vorbbis stereo-specific channel coupling discussion" document, it's described how the decoupling process works for Square Polar Mapping (and it is fairly clear explained), but it does not describe
