similar to: colored shading lines

Hi, I'm sure this should be fairly simple to do but I haven't found an example. I have 10 data points which are plotted as a line, I want to shade under this line with a colour. Other examples have shading under curves where there are two sets of data use polygons. mydata <- c(268,251,254,250,244,246,247,243,241,243) plot(mydata, type="o")

Hi, I have a contour plot and I want to shade a polygon (the area below a line) but the polygon shading wipes out the contour lines. Does anybody know how to shade the polygon and still see the contour lines? Thanks. Jeff

Hi there, I'm having trouble working out how to change the colors of polygon shading lines. If I plot a polygon with polygon(poly,density=30,borders=gray(0.5)) I get gray borders but black shading lines; I have tried adding col=gray(0.5), bg=gray(0.5) and fg=gray(0.5), but no luck. How can I change the colors of the shading? The help file doesn't seem to detail this, so any

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

Dear useRs, Following the given codes below, I generated a plot that has 6 regions around a center point (IL), with 5 regions containing a point (L1, L2 to L5) and sixth vacant region. I want background of all the filled regions turned "green", while "red" for the vacant region. Can it be done through a quicker way? Thanks in advance ###Codes start from

Colleagues OS 10.5 R: 2.10.1 I have a simple x-y plot for which I would like to shade the lower (or upper) part of the interior region (i.e., the area bounded by the axes). If the delineation between top and bottom were linear, it would be use to use the polygon function. However, the delineation is a curve (which I can describe by an equation). In theory, I could divide the x-axis into a

Hello again With the poylgon function it's possible to plot shaded areas under a curve. But somehow it connects the start and the endpoint of a line and fills whats between them. I would actually like to set the boarders of the shading by two min and max curves, but I failed. i tried stl like: polygon(min, max, border=0), where min and max are my curves plotet by plot(max) lines(min)

How can I resolve this problem?... As a general example, plot (1:4) polygon(c(0,0,5,5),c(0,5,5,0), border="lavenderblush1", col = "lavenderblush1") ###see how this overlays the axes lines #I have tried... for (k in 1:4) axis(k, lwd.ticks=0, label=F) #...but this misses the corners Any suggestions? -- View this message in context:

Hello, I have a question regarding shading regions under curves to display 95% confidence intervals. I generated bootstrap results for the slope and intercept of a simple linear regression model using the following code (borrowed from JJ Faraway 2005): > attach(allposs.nine.d) > x<-model.matrix(~log(d.dist,10))[,-1] > bcoef<-matrix(0,1000,2) > for(i in 1:1000){ +

Thanks for the question. Here is a sample of the code for my plot: Top = c(34, 39, 42, 45, 46, 41, 41, 40, 43, 38, 33, 33) Bottom = c(24, 29, 32, 36, 32, 34, 32,41, 40, 39, 29, 24) plot(1,1, col = "white", xlim = c(1.3,11.7), ylim = c(0,80), axis = FALSE, xaxt = "n") axis(1, at = c(1:12)) polygon(c(c(1:12),c(12:1)), c(top, bottom), col =

Hello, I cannot figure out how to shade between two lines in a plot. For example, if I am trying to plot a confidence envelope and I would like to shade the interior of the envelope grey. Is this possible in R? Thanks in advance. Heather Lynch

Hi, Can someone help me with the following? I currently have the following plot: plot(c(0,14,0,14),c(0,5,0,5),ann = FALSE, xaxs="i", yaxs="i",bty="L" ) polygon(c(0,18,18), c(0,6,0), col='light grey', border = NA) polygon(c(0,18,18), c(0,2,0), col='grey', border = NA) However, I would like to make such a plot, but where there is a continuous shading

Dear R-Community, I have the following problem and was wondering whether someone could help me out. I have a number of time series of discharge (up to 3000 data points in some cases) which I would like to compare on the same line plot by shading the area between some of them. Can anyone tell me how to do that? I have tried to fiddle around with the polygon function, but the curves interact a

I have a set of 52 weekly values, one is the desired high lake stage for a week, and the other is the desired low lake stage for each week. It looks like this: week High Low 1 16 14.5 2 16 14.5 3 15.95 14.45 4 15.84 14.34 5 15.73 14.23 6 15.61 14.11 7 15.5 14 8 15.38 13.88 9 15.25 13.75 10 15.13 13.63 .... 52 15 13.5 I can plot out two nice curves

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

Dear Listers, I am drawing a plot of two density curves, for male and female incomes. I would like to shade/hatch/color (whatever) the areas under the curves which are distinctive for each gender. This is the code I have tried so far: m <- density(topmal.d$y, bw = "sj") f <- density(topfem.d$y, bw = "sj") par(mfrow = c(1,1)) plot(x = c(0,400), y = c(0,0.02), type =

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

Hello! I want to use the Icens package for analyzing interval-censored data. This code from the manual gives me what I want. library(Icens) data(cosmesis) csub1 <- subset(cosmesis, subset=Trt==0, select=c(L,R)) e1 <- VEM(csub1) plot(e1) However, I would like to change the color of the shading from green to something less green, say gray. Any ideas how I could do that? I looked at par, but

I have the following code for the minimum and maximum of my prediction interval > y.down=lines(x[x.order], set1.pred[,2][x.order], col=109) > y.up=lines(x[x.order], set1.pred[,3][x.order], col=109) domain=min(x):max(x) polygon(c(domain,rev(domain)),c(y.up,rev(y.down)),col=109) It doesnt seem to shade the right region, it gives me a trapezoid. Any help? Thanks!
