How can I make one point graphics with transparency These are all sp classes: plot(polygons_area,axes=TRUE,asp=1.5,main="Title",xlab="Latitude", ylab="Longitude") points(observations2000,type = "p",pch=21,col="green") points(observation1999,type = "p",pch=21,col="blue") points(reference.points,type =

Hi, The current lattice/grid packages seem to position character plotting symbols (e.g., ".") differently than the base function points. The following shows what I mean: ## plain old points() positions the pch="." right at y = c(0,1), ## and thus abline(h = c(0,1)) completely hides the points "." ## (provided the output device has enough resolution, like

Hi everyone, Is there any reason why we should not automatically coerce a factor supplied as an argument to col in a plotting function? The following modification (to R-1.6.1) seems pretty harmless > plot.xy function (xy, type, pch = 1, lty = "solid", col = par("fg"), bg = NA, cex = 1, ...) { if (is.factor(col)) col <- codes(col)

Hi R-help, We are using R 2.2 on Win XP and have a detail question on how the legend can be optimised. We use the following; -> plot(,type="b",...) The lines in the plot do not cross the points. How can we obtain the same effect in the legend? (points without a line through them..) We tried setting the pt.bg to white but this did not help. See script below. thanks, Jan

Please excuse me for asking such basic questions: Here is my code > y=c(1.21,0.51,0.14,1.62,-0.8,0.72,-1.71,0.84,0.02,-0.12) > ybar=mean(y) > ll=length(y); > ybarv=rep(ybar,ll) > x=1:ll > plot(x,ybarv,pch=1) > segments(x[1],ybar,x[ll],ybar) What I get is a collection of small circles, with a segment "on top" of the circles, which is almost what I want. But I

In several places, we have the convention that col = NA means `` don't draw '', e.g. for points() or rect(). For col = <vector> this only works when the vector is integer (numeric), but not in other cases. I think this is a bug, even though not in the strict sense, since we don't seem to claim it should work.. Example: plot(1:10, col = c(1:4,NA,NA,4:1)) ## fine

Hello! After performing an analysis with betadisper, package vegan I would like to plot the results - so far, so good. But I would also like to "tune" a little bit the plotting characters, as '+' and 'x' are a little to similar... My (boiled down) code: [See session info at the bottom of the mail, vegan is vegan_2.0-3] mod <- betadisper(mydata, mygroups,

Hi all, I ran the code: > s <- stack(replicate(2, raster(matrix(runif(100), 10)))) > xy <- data.frame(coordinates(sampleRandom(s, 10, sp=TRUE)), + z1=runif(10), z2=runif(10)) > levelplot(s, margin=FALSE, at=seq(0, 1, 0.05)) + + layer(sp.points(xy, pch=ifelse(pts$z1 < 0.5, 2, 3), cex=2, col=1), columns=1) + + layer(sp.points(xy, pch=ifelse(pts$z2 < 0.5, 2,

I'd like to suggest changes to three help pages, regarding the use of pch=NA to suppress plotting symbols. See below. Arni R 2.0.1 on WinXP === help(bxp) === The argument outpch=" " needs to be replaced with outpch=NA in two places. I actually wrote this part of the documentation myself at one point, but have now realized that pch=NA and pch=" " are not the same:

Dear R-users, For the past few days, I have been trying to find the reason why some of my plots were showing symbols of different sizes, while I thought I was using the same .cex arguments everywhere. The problem is exemplified by the following example code where the xyplot and grid.points functions are used. The scaling factor is set to 0.84 in both the functions settings, but one can see

Hello, I am creating a scatter-plot in lattice, and I would like to customize the size of each point so that some points are larger and others smaller. Here's a toy example: library(lattice); temp <- data.frame( x = 1:10, y = 1:10, cex = rep( c(1,3), 5), groups = c( rep("A", 5), rep("B", 5) ) ); xyplot(y ~ x, temp,

The following code snippet crashes R (under Windows and Linux) for both R-2.4.1 and R-2.5.0 RC as of yesterday: set.seed(1) H <- rnorm(400000) temp <- rnorm(400000) plot(H, temp, type='s') # (no, it was not my idea to do something like that!) I *guess* it is some overflow in plot.xy() which calls .Internal(plot.xy(xy, type, pch, lty, col, bg, cex, lwd, ...)) but

Dear all, consider: ### x <- round(rnorm(50)) stripchart(x, pch = 21, col = "black", bg = "pink", method = "jitter") points(0.5, 1, pch = 21, col = "black", bg = "pink", cex = 2) ### Under R 2.9.0 the points produced by stripchart are not colored, while points() gives the desidered output (magnified here by cex). I found a simple workaround

Hi all, I'm trying to add single points with known coordinates to a level plot, but could not find the proper answer. I got to know that layer() function is good for this, but I don't know which package is related to this function. The source is here: https://stackoverflow.com/questions/28597149/add-xy-points-to-raster-map-generated-by-levelplot but my question is a little different as I

Dear R-list Suppose I have a data set stored in hmet, for which I did get confidence limit on a linear regression as shown below. My question is how I can subset only data points which are within the confidence limit. Thank you.

I'm trying to use plotting character to encode the variable "block" from my dataset in a conditioned lattice graphic (R 1.9.0 on Mac OS 10.3.3). The data I'm using is the dataframe "dryoutcover" which is here (4k): http://anthony.darrouzet-nardi.net/downloads/dryoutcover.Rdata The code that generates my graphic almost correctly is as follows: xyplot(coversage ~

Graham, Confirmed. I will pass that along to the R team. As 1.8.0 is in code freeze, this may not get addressed, unfortunately.
