similar to: Placing of legends

Hello, I have a time series plot drawn using 3 different colored lines, each line corresponds to different category group. I'd like to put legends on the plot. I am using "legend" to do this, however, I can either specify lty or col in legend. Will I be able to do the following in the legend box: a solid black line then g1, a solid red line then g2, a solid blue line then g3?

Hi: I'm trying to plot dates on the x-axis of a code, but the legend is not being displayed. I receive the following error: Error in match.arg(x, c("bottomright", "bottom", "bottomleft", "left", : 'arg' should be one of bottomright, bottom, bottomleft, left, topleft, top, topright, right, center In addition: Warning message: longer

Hi, all: Is there an automatic smart legend for R? Since my R code is running in a row, which will produce a bunch of R plots in a single run, some of the produced plots are really "ridiculous". Because my legend is fixed to "topleft", sometimes, which occludes the key parts of the figure/plots, but most of the time, the legend works just fine. I'm wondering is there a

Dear R Users, I am quite surprised to see that mtext gives different results when it is used with 'pairs' and with "plot'. In the two following codes, it seems that the 'at' argument in mtext doesn't consider the same unit system. I would appreciate your comments on this issue. Sebastien ##### Pairs mydata<-data.frame(x=1:10,y=1:10) par(cex.main=1,

Dear all; A simple? question. I'm having a problem with a math expression in the legend of a plot and I haven't found the way to get this to work, so any help will be appreciate. Basically I want to include in the plot is the R-squared and its numerical value, so I tried this: R2c<-0.82879 # R-squared of calibration model plot(1:10,1:10) legend("topleft",

Hello everybody, Is there a way to add a subtitle to a lattice key? It is important form me that the subtitle must be linked to the key because those graphs are produced on a daily temporal scale, and the numbers of rectangles from the key may be different from day to day. Thank you, Alexandru Dumitrescu [[alternative HTML version deleted]]

Hello, I want to add text annotation about correlation on "pairs" plots. I found that I could pass a function to the "panel" argument of pairs : panel.annot <- function(x, y, ...) { points(x, y, ...) c <- cor.test(x, y) legend("topleft", legend=substitute(rho == r, list(r=sprintf("%.2f", c$estimate))), bty="n") } And then :

I am trying to save some graphical output including a legend in the Windows Enhanced Metafile (EMF) format. This fails when xyplot() is used rather than plot(). Here is a simple example: require(lattice) a <- c(1:10) b <- c(2,4,5,2,3,5,7,8,9,5) # Output can be saved (or copied to the clipboard) as a Windows EMF image file # from the Graphics Device output window. plot(a , b)

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))

Dear R-users, I would like to add a legend at the bottom of pairs plots (it's my first use of this function). With the plot function, I usually add some additional space at the bottom when I define the size of the graphical device (using mar); grid functions then allows me to draw my legend as I want. Unfortunatley, this technique does not seem to work with the pairs function as the

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

I am creating a CDF plot function more user-friendly than any default r function. Depending upon the bimodality of the data (it is often bimodal), or any other strange data trends, the points can end up gathering in just about any corner of the plot. So, when I add a legend, whether I choose to add it in the bottom right, top left, or wherever, it will sometimes end up putting the legend right

Dear R-Users, I am looking for a way to get legends placed automagically in an empty spot on a graph. Additional complication comes through my useage of multiple graphs on the same plot through mfrow. Is there a way to achieve this in R ? I have legends for each of the sub-plots. Many thanks in advance, Tolga Generally, this communication is for informational purposes only and it is not

Dear community, I've plotted data and coloured depending on the factor variable v3. In the legend, I'd like to assign properly the same colors than in the factor (the factor has 5 levels). I've been trying this but it doesn't work. plot(var1, var2, xlab = "var1", ylab = "var2", col =var3 , bty='L') legend(locator(1),c("level 1 var3",

Hi to all, I'm sorry for posting this question, I am sure I am missing something important but after reading the documentation I cannot find where the problem is. I want to add a legend to a figure. If I use a simple example drawn from the R Reference Manual such as, for instance: x <- seq(-pi, pi, len = 65) plot(x, sin(x), type="l", col = 2) legend(x = -3, y = .9,

Hi R users: I will like to have a legend with math symbols and also with the value of a variable. But I cannot obtain both at the same time (symbol + value of a variable): Here is a reproducible example: m1<-5 m2<-12 plot(1:5,1:5,type="n") legend("topleft",legend=c(paste(expression(mu),"=",m1),expression(paste(mu,"=",m2))),lty=1:2) Thank you for

I'm trying to automate making a bunch of figures and I need a way to automate legend position. As I understand it the legend is placed based on coordinates. I don't know before hand what the coordinates are going to be. On one graph my y axis might go from -50 to -10. On another it might go from 0 to 180. Is there any way to query where the origin is? Or is there another way to

Thanks a lot to Demitris for a prompt answer some minutes ago on another tread (see below). To avoid excess mails on the list, I move onto next question: I have another small plotting problem that confuses me. I want to plot results from a field trial series, using the numbers of the trials as symbols in the plot. pch = as.character(trial_no) works fine, but truncates the trial number to the
