Hello all, Is it possible to change the radii line type in radial plots? I wasn't able to find anything online.

Hi there. I have been plotting some circles using 'symbols', with radii representing my data, but the radii looked incorrect. It seems to happen with a single circle too: Symbols ( 0, 0, circles = 40, xlim = c(-40, 40), ylim= c(-40, 40)) If I put a ruler up to my monitor (technology!) to compare the radius with the axes, the circle isn't radius 40; it is close...

...umented predation occurrence (binary?) in these structures and calculated several possible explanatory variables describing the spatial heterogeneity in several scales. At the landscape scale I have calculated the percentage of different land-uses (7) in buffers around the structures with changing radii (100m, 250m, 500m, 1000m and 2000m). For each radii I have generated a set of all possible models from the given 7 variables related to this radii. I have tried to account for random effects. A spatial random effect ? the structure itself as a repeated measurement, by adding the term (1|Road_S...

Anybody know how to rotate shapes generated with the 'points' function? I'm trying to place points around a radial diagram such that the y-axis of individual shapes are oriented with the radii of the circle rather than the y-axis of the larger plot area. Perhaps something analogous to the 'srt' and 'crt' functions for text that appear under 'par'? Thanks, Rich

How come I am seeing only two sectors? Also the length of the radii show the ratio compared to the other values of the columns (e.g. "x"), correct ? (And there is no direct relationship between the values of a single row, or is there?) I am using R 1.12.1 for Linux, Many Thanks JP [[alternative HTML version deleted]]

...ated a symbol plot with circles that represent the mean temperature at lat/lon locations over the United States. The radius of the circle corresponds to the mean temperature. I would like to add a legend that identifies a range of temperatures (e.g. 0-10, 10-20, etc) with circles of the appropriate radii next to them. I've read the manual on how to add a legend, and I'm fine with adding one to the plot. However, I cannot get circles of different sizes to come up next to the ranges in my legend. All that is coming up are circles of all the same radius. In looking at the R manual, it appears...

...his is mainly a bugfix-release. If you fit multi-response models, you are strongly engouraged to upgrade! The main changes since 1.2-0 are - Fixed bug in kernelpls.fit() that resulted in incorrect results when fitting mulitresponse models with fewer responses than predictors - Changed default radii in corrplot() - It is now possible to select the radii of the circles in corrplot See the file CHANGES in the sources for all changes. The pls package implements partial least squares regression (PLSR) and principal component regression (PCR). Features of the package include - Several plsr alg...

I using oldlogspline (from logspline package) to model data distributions, and having a problem. My data are search area sizes. They are based on circular search radii from random points to the nearest edge of the nearest grass tussock. Search area sizes are distributed from 0 (the random point intercepts a tussock) and upwards (as points are further from any tussocks). The density of all my distributions (using doldlogspline) are highest at size=0, and decline a...

Hello, could please somebody help me. I want to apply the mark correlation function but for radii up to 75 meters (in 75 individual 1m steps). Unfortunately, "There is a sensible default for the values of the argument r at which the mark correlation function kf (r) should be evaluated", so that I do not get results for r > 25m. Can I change something in the function to get the requ...

...42 25 and get a graphic with 4 superimposed stars of different colors superimposed showing the shape of the distribution for each year. The data is percentsges of students scoring in each category, summing to 100. There are actually scores for Literacy and Math, so I might display 8 radii instead of the 4 above. And the dataset/graph would be repeated for comparing various subpopulations. Any pointers would be welcomed! Thanks!

Hi all,I would like to draw a simple circle where the color gradient follows the rule color = 1/(r^2) where r is the distance from the circle. I would also like to add a color bar with values going from -40 to -110 (and associate those with the color gradient that fills the circle). So far I experiemented with draw circle

...ruct a centroid plot using canonical values from a MANOVA. I know that from the summary.manova object you can get Eigenvalues, and the H and E matrices (from SS$Treatment and SS$Residuals), but I am at a loss to get the loadings for the canonical values, nor values for the centroid centers and radii. Is there a package that does this that I am just missing, or any helpful code out there that I have been unable to locate? Thanks so much! -Jarrett p.s. There are a bunch of ecologists and evolutionary biologists here at Davis who, as a group, have just taken it upon themselves to learn R,...

I''m working on a mapstraction implementation modeled after the radius search feature. (http://mapstraction.com/demo-radius.php) I''d like to recognize when the user extends the radius beyond the visible edges of the map and adjust the zoom level. I''m not seeing how to test this when redrawing the circle. I thought maybe I wanted to use polylineCenterAndZoom()

I have to solve a clustering problem. My first step is to determinate the number of clusters, that's why I 'm using the Calinski index ( [tr(b)/(k-1)]/[tr(w)/(k-1)] ) which i try to maximize to have the best number of clusters. A function is already implemented in R to calculate this index : clustIndex(cl,x, index="calinski") where cl is the result of a clustering method ,

Hi all, I have encountered a problem which appears to have defeated my (admittedly nascent) R skills. I want to draw a spider plot with many cases (just over 300). I am primarily interested in the difference between 4 categories of cases, and want to display them as different colors. the col.stars parameter does not change the color of the lines (which I'm after), but fills the stars in
