Hi, Is there a simple way to suppress the plotting of polygon boundaries with spplot() ? # simple list of 12 colors cols <- brewer.pal(12, "Paired") # plot pile of polygons, with 12 classes: spplot(x, zcol='class2', col.regions=cols, scales=list(draw=T), xlab="Easting (m)", ylab="Northing (m)") ... seems to work well. However the polygon boundaries

In Germany the Unemployment Agency uses a sectioning of the german map that is different from the usual Administrative Boundaries. Some demographic data are available in Administrative Boundaries only, some in Unemployment Boundaries only. I would like to generate estimates in one boundary system of data availabe in the other boundary system, and would appreciate advice concerning the following

Dear R users, I still feel new to R so please apologize if I am doing something stupid here. My use of the polygon() function produces a result that I cannot comprehend: In a plot, I would like to shade the area below a normal distribution. However, I do not want the entire area to be shaded, but just the area on the right side of a vertical line that I draw through the distribution (in

Hi Paul, Great, thank you for looking in to this, and I'm glad that you're able to reproduce it at your end too. From your reply, I'm happy that it seems like the fix may be fairly trivial, but I understand the necessity for caution. If there's anything else I can do to help, please do let me know. Thank you again, Best, Lee On Monday, 4 March 2019, Paul Murrell <paul at

Hi everybody, I have a matrix with 3 columns (Date, MeanArea and SdArea). I want to draw a figure showing the variable MeanArea in terms of the Date. But instead to use the variable SdArea as bar error, I want to use ?polygon error?. I use this code but the output does not seem good.

Hi (cc'ed to r-devel where further discussion should probably take place) Thanks Lee. I see that problem. There is a "+ 1" in the Cairo device code for setting the clipping region (https://github.com/wch/r-source/blob/ba600867f2a94e46cf9eb75dc8b37f12b08a4561/src/library/grDevices/src/cairo/cairoFns.c#L156) Remove the "+ 1" and the problem goes away (for your example

Hello all, When producing a plot in R using the cairo_pdf device, the resultant plot does not respect the plotting boundaries. Lines and shaded regions will spill over the lower x-axis and the right-side y-axis (sides 1 and 4). I would like to know if it is possible to fix this behaviour when using 'cairo_pdf' in R? As an example, see the image at this web link:

HI, Sorry Carl, I received your message in my spam folder. Sarah proposed me a good example of code.

I am stuck at the following problem. I have two moving averages. One is faster than another. After plotting them I need to shade area between them in green when the faster is above slower and red where faster is below slower. Something like this: http://charts.stocktwits.com/production/original_9205513.png?1345576091 I tried with polygon but I can't do it. Any hints? Regards olo -- View

The angle is not based on the polygon edges, but it can seem that way if you do not use the asp=1 argument in your plot. Try this example, > plot(1:10, 1:10, type='n') > x <- c(1, 3, 5, 3) > y <- c(3, 5, 3, 1) > polygon(x, y, angle=0, density=10) > polygon(x, y + 4.5, angle=45, density=10) > polygon(x + 4.5, y + 4.5, angle=90, density=10) > polygon(x + 4.5, y,

Dear R users; Is there any way to intersect a filled contour image and a polygon? My problem is that I want to create a kriging map and the boundaries of my map are given by the coordinates of the polygon. So far I can superompose the polygon in the filled.contour image but I don't know how to get rid of the contour image outside of the polygon boundaries. Any hint will be appreciated PM

Hi all, I have a matrix dd with dates and data. i WANT to create a grpah with shade between the line and the zero axis. I?m trying to use polygon but something doesn? t work Imagine. I want to plot g<-read.table("dd.txt", col.names=c("fecha","DP")) g$fecha <- as.Date(g$fecha, format="%d/%m/%Y") t<-g$fecha st<-length(g$DP)

Forum, I have two time series that I plot up using the data/code below. The x-axis shows weekly time step starting on 6/3/1999 (SP=10) and ending on 10/25/2007 (SP=448). I'm trying to shade between the two lines in a similar fashion as the graph found here: http://addictedtor.free.fr/graphiques/RGraphGallery.php?graph=122 Can the polygon function be used to do this? There are lots of

Dear R-helpers, the problem I'm facing today is to convince lattice to paint some areas in gray. The areas I would like to have in gray, are confidence bands I've googled around in the mailing list archives and eventually find some clues. This link is my starting point http://tolstoy.newcastle.edu.au/R/e2/help/07/04/15595.html I'm reproducing here the code for your convenience est

Objective: Determine if a set of x and y-latitude points are inside of a polygon using R. Lets say I have 9 polygons. Where I have labeled the polygons to be checked from 1-9. The problem I?m running into is running the point.in.polygon to check if those points are in one of several polygons, as my code overwrites the result. To accomplish this I am using the R-built in function called

Dear R-users, Suppose I have the following x-y coordinates which give the boundaries of a polygon: > x <- c(5,4,5,9,6,6,4,7,10,7,10,4,10) > y <- c(6,3,2,6,3,7,5,4,4,7, 5,4, 6) I would like to plot the following graph: > plot(x,y) > ord <- c(7,12,2,3,5,8,9,11,13,4,10,6,1) > polygon(x[ord],y[ord]) How I can obtain the above ordering (in the example an anti-clockwise

Filling polygons with lines is a throwback to the time when the height of quality graphics was the mechanical pen plotter (a device that used a pen in a mechanical arm to draw the plot on a piece of paper). Computing and printing technology has advanced quite a bit from that day, so you may want to reconsider why you want polygons filled with lines instead of just a solid color (and I consider

I am using color2D.matplot to plot a matrix about 400 by 200. The values in the matrix are 0:5 and NA. The resulting plot is not color, but shaded b/w. I tried to figure out how to add colors, I would like something like c(blue, green, red, cyan, green) #example motifx <- matrix(NA, nrow=100,ncol=20) motifx[,1:5] <- 1 motifx[,6:10] <- 2 motifx[,11:15] <- 3 motifx[,15:19] <- 4
