similar to: Changing the origin in polar.plot in plotrix package

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

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

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 =

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....

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

Hi, how can I reverse the radius axis of plotrix's polar.plot function? Perhaps this sounds strange, but I use the radians for angles as well: In the center is zenith and the corresponding angle is 90?, not 0. See an example plot at http://www.mysundial.ca/tsp/images/sun_chart_50_solar_polar.jpg dirs<-c("S","E","N","W")

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

Dear R-help, I have a matrix of data values specified in polar coordinates, i.e. (r,theta). I know that I can transform this image to Cartesian coordinates and then use image to display the results, however, I want to display the image as is, without any coordinate transformations. This would require displaying individual "pieces of pie" colour-coded by their data value. A comparable

Dear List, Following the link below ( http://rgm2.lab.nig.ac.jp/RGM2/func.php?rd_id=plotrix:clock24.plot) I got an interesting polar plots which displayed my data and the time of observation. Thank you very much for providing such details. However, I have two set of data which I wish to display in the same polar plot. I tried using points to add the second data but could not succeed. That is,

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 am currently using the polar.plot function in the plotrix package to graph data. Unfortunately, it seems that the default for the labels is to have a background color that is covering the line representing my data, making it difficult to read. Is there a way to make this label background transparent? Example: lengths <- 0:72 bearing <- seq(from=0, to=360, by=5)

Hello, Everyone. Does anyone know how to create a Nightingale’s Rose chart by using R? Hopefully, the graph could be displayed like this: http://mbostock.github.com/protovis/ex/crimea-rose.html Thanks a lot. Kind regards, Henry [[alternative HTML version deleted]]

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

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 am attempting to create a polar chart (using plotrix polar.plt) and I need to colour a segment of the grid to indicate an area of interest, say from 90-120 degrees, for arguments sake. Is this possible? I can colour the whole grid by passing the grid.bg parameter through to radial.plot but I cannot find a way to colour a segment. thanks, Darren -- View this message in context:

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

Dear R users, The following issue has been already documented, but, if I am not mistaken, not yet solved. This issue appears while trying to plot arrows with "geom_segment" (package ggplot2), with polar coordinates ("coord_polar"). The direction of some arrows is wrong (red rectangle). Please find herewith an example. Does someone know how to deal with that issue? Best

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
