similar to: change layout of legend

Hi, I seem to be unable to get a mixed legend that has lines *or* polygons (not both). For example: ppi <- seq(0,2*pi,length.out=21)[-21] frame() plot.window(ylim=c(-5,5),xlim=c(-5,5),asp=1) polygon(cos(ppi)*4+rnorm(20,sd=.2),sin(ppi)*4+rnorm(20,sd=.2), col="green",border=FALSE) polygon(cos(ppi)*2+rnorm(20,sd=.1),sin(ppi)*2+rnorm(20,sd=.1), col="blue",border=FALSE)

To whom it may concern: The help page for ?legend refers to a `title.cex` parameter, which suggests that the function has such a parameter. As far as I can tell, though, it doesn't; here's an example: > plot(1,1) > legend("topright",pch=1, legend="something", title="my legend", title.cex=2) Error in legend("topright", pch = 1, legend =

Hello, Is it possible to change the text size of the title in a legend of a R plot? I tried to directly change the title.cex argument but it seems not to work. Trying : Horizo <- c(1,2,6,10,20) legtext <- paste(Horizo,sep="") legend("topleft", legend=legtext,col=col,text.col=col,lwd=lwd, lty=lty,cex=1.1,ncol=3,title = "Horizons",title.col

Right, that's my point. The help page mentions a `title.cex`, like I said; saying that `cex` sets the default `title.cex` sure implies to me (and presumably to the other people whose discussion I linked) that a `title.cex` parameter exists. Since no such parameter exists, this bit in the documentation is misleading (suggesting that there is a `title.cex` parameter which can be set, when there

HI there, I want to add a legend to a plot using the density and angle argument, so patterns with lines in different angles are used in the plot and should be referred to. When I use default settings, the filled boxes are too small. With the cex argument I can enlarge the whole legend, but then the text gets too big. How could I just increase the size of the single boxes and not the text. I

I'm using the image.plot() function (fields package), but I want to enlarge the characters of the legend (as they are too small to be read in a combined figure), but there is no way I can find a command to do this. I can enlarge the legend bar (with legend.witdh), axis character size (cex.axis) or the total legend size (legend.shrink), but not the character size of the legend characters

Hi everyone. I have a quick question regarding the look of my legend in my plot. As you can see in the next figure, I have 3 series. http://r.789695.n4.nabble.com/file/n3067466/legend.png However, I find rather difficult to differentiate the series 1 and 3 according to their line type (lty). I would like to know if it was possible to make the line type in the legend to appear more clearly.

Hi, I've looked at the parameters available for the legend function and cannot find a way to change the distance between the top of the box surrounding a legend and the legend's title. I have a math expression that raises the height of my title. If you don't mind the non-sensical title I give to the legend for this plot (Figure 3.20 in R Graphics): with(iris,

Is there a simple way to put a legend outside the plot area for a simple plot? I found... (at http://www.harding.edu/fmccown/R/) # Expand right side of clipping rect to make room for the legend *par(xpd=T, mar=par()$mar+c(0,0,0,4))* # Graph autos (transposing the matrix) using heat colors, # put 10% of the space between each bar, and make labels # smaller with horizontal y-axis labels

Dear R users, I am new to R and I couldn't figure out how to solve the following problem: I am trying to put a legend below two plots using the code below. The legend appears in the second plot, but I want the legend to appear below the two plots in the center of the total chart. At the moment the graphic looks like this: http://i48.tinypic.com/2h2fvhf.jpg [code] layout(matrix(1:2, nrow=1))

Legend titles work in linear plots: curve(1/x, xlim = c(0, 1)) legend(x = 'topright', inset = 0.04, legend = '1/x', lty = 1, title = 'Legend Title') But when you change to a log plot on either dimension things get screwy: curve(1/x, xlim = c(0, 1), log = 'y') legend(x = 'topright', inset = 0.04, legend = '1/x', lty = 1,

Dear R Community, I'm using xyplot in Lattice with a legend and a title on the legend. The title on legend is being cut off, as can be seen by running the code below. The legend is on the right, but I would like to get to the top right of the graphics window. Is there a way to get the legend title to display correctly and move the whole legend up the the top right? Thanks, Justin ### R

Dear list, I've written a small utility function to add arbitrary legend(s) to a lattice graph (or a combination of them), much like the legend function of base graphics. I though perhaps it could be useful to someone else, or improved by suggestions. I understand this goes against the lattice paradigm somewhat, in that you short-cut the link between group variables and the

Dear Rs I have a 3x3 multiple plot. I would like to have a overall legend in the outer right margin. From the help archive, I found that it can be done by setting par(xpd=NA). However, I couldn't find the correct values for x and y co-ordinates for the legend. Please find the code snippet below: par(mfrow=c(3,3), mar=c(4,4,0.9,0.5), oma=c(1,2,2,4),cex.main=1.1)

Dear R-devels, I'd like to create a plot method for a class of objects that passes the '...' argument to both plot() and legend(), e.g., x <- list(data = rnorm(1000)) class(x) <- "foo" plot.foo <- function(x, legend = FALSE, cx = "topright", cy = NULL, ...){ dx <- sort(x$data) plot(dx, dnorm(dx), type = "l", ...) if (legend)

Hello, I'd like to ask, how to adjust the space between symbol/line and text in a legend. My legend() is build like that legend(xmax-netzdiff/11, # shouldn't matter here ifelse(ydiff>=0, # ymin-6.5*(netzdiff/11), # ymax-netzdiff/11), # c("stehender Stamm","Windwurf",

I need to have the maths symbol for >= in the legend, and to substitute threshold variable with its value. Somehow, various attempts weren't successful. Please help. threshold <- 0.5 plot(NA, xlab="", ylab="", main="", axes=F, xlim=c(0,1), ylim=c(0,1), xaxs="i", yaxs="i") legend(x=0, y=1, fill=c("orange", "white",

Hello, In order to reduce the width of my legend in a plot I introduced line jumps in the title. Here's the problem; the legend box hasn't adapted accordingly and part of the title is printed out of the frame. See the example below: plot(1:10) legend("bottomright", bg="white", fill=c(7,8,12,13,19),

I could not find a way to specify the border color of the boxes drawn in a legend, so that the legend can match exactly the colors of the actual plot (e.g. in the case of two superimposed histograms which have different shading and different borders). Indeed, the legend function seems to hard code the color "black" for the borders in this call: rect2(left = xt, top = yt +

Here's a simple example: x <- 1:5 plot(x,x^2) lines(x,x^2) points(x,x,cex=2) lines(x,x,lw=3) legend("topleft",legend=c("y=x^2","y=x"),pch=1,pt.cex=1:2,lw=c(1,3)) The thickness of the circles in the legend changes with lw. If you change the lw argument in legend to lw=c(1,1) then the thickness of the circles goes back to normal. How can I make the above
