Hi everyone. I have a linear regression where I retrieve the R2 like this: r2 = sprintf('%4.2f %s',(summary(reg1)$r.squared)) In my figure I have a legend where I would like to add that R2 value to the legend text. Something like: My text R^2 = r2 legend('topright', inset = .05, title='light ratios', pch = c(21), c(paste('Green/Red', R^2, '=', r2)),

Hi all. I'm ploting a raster and I can't find the proper way to move the legend. For example, r = raster(system.file("external/test.grd", package="raster"))plot(r) How can I put the legend at the desired position? Thank in advance,Phil [[alternative HTML version deleted]]

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

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 =

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

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,

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))

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

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

I have a bivariate plot of axis2 against axis1 (data below). I would like to use different size, type and color for points in the plot for the point coming from different region. For some reasons, I cannot get it done. Below is my code. col <- rep(c("blue", "red", "darkgreen"), c(16, 16, 16)) ## Choose different size of points cex <- rep(c(1, 1.2, 1), c(16, 16,

Hello, Recently, I have asked for a help with building graphs, and I got few great advices. Now, my appetite is growing :) and I wander how to add legend for two (or more) lines in following example: matplot(DAT[, c(3,4)], type="b", ylim=c(0,8), xaxt="n", yaxt="n", + pch=c(21,22), col="black", lty=c("dashed","solid"), xlab="",

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 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-people, are there any way to change the size of legend in barplot? I have tried various versions of cex, both as par(cex.*= ) and barplot(..., cex.*= ). So long without success.

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",

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

Hello everybody, Is it possible to coax legend() into displaying more than one simbol per line in legend? I have a graph like the one attached to this mail; I would like to reorganize the legend in such a way that the duplicate text would be omitted, i.e., the first line would read <square> <triangledown> "increasing frequency" and the second one would read <circle>

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",

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 +

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
