Hi List, is sth. like the following possible: legend(x,y,c("A","B","C"), lty=list(1,"42","11")) ? Or: is there a possibility to define a solid line using the "string" mode for lty?

Dear all, I have a multiline plot with each line labeled with a different letter. But I'm not able to make the legend display the same kind of pattern '-a-', instead the letter is overwritten by the line. A simpler legend with only the letter is not very visible and the pt.bg does nothing with letters. Any idea? plot(1:10,10:1,lty=1,type='b', lwd=2,pch='a')

Hi all, Is it possible to change the filling of the squares used to represent the colour legend in a bar plot with ggplot? in this example, fillings are raven black, I'd like them white. ggplot(diamonds, aes(clarity, colour = cut)) + geom_bar() Regards -- ------------- Benoit Boulinguiez Ph.D student Ecole de Chimie de Rennes (ENSCR) Bureau 1.20 Equipe CIP UMR CNRS 6226 "Sciences

Hello, I am trying to add a less than equal to symbol in a ggplot2 legend text. See sample code below. I have tried using the expression function and \u2264. I also tried adding labels to legend.text under theme. Neither of these 3 options work. Please help, Mahesh ++++++++++++++ Extra.column=ifelse(data[,covariate]>cutpoint,1,0) Grp1 <- "\u2264 1.5" Grp2 <-

Dear experts, I am trying to understand why is it that when I paste (into the R console) the following code to select an option from a list: require(tcltk) tt<-tktoplevel() tl<-tklistbox(tt,height=ntx,selectmode="single",background="white") tkgrid(tklabel(tt,text="Select the legend of" )) tkgrid(tl) treatments<<-levels.tx for(i in

In ggplot2 how do you justify the legend text ? In the example below the opts(legend.text = theme_text(size = 9,hjust=0)) changes the size of the text OK but it remains right justified. > mydata=data.frame(RowID=c("A","B","C"),Name=c("long long long long long name","short name ","medium medium name"),Speed=c(100,140,120)) >

Hello dear list, I just cannot figure out how to do this and didn't find a solution for my specific problem. I want to place a centered horizontal legend between 4 plots. That's no problem. The problem is: As soon as I specify the "text.width" parameter to separate the two legend entries, the legend is not centered anymore. I thought the 'xjust' parameter would do what

hi, i'm trying to prepend some plain (i.e. unevalutated) text to a typographically evaluated R expression in a legend(...) call. here's a working legend(...) call that is close to what i'd like (where x and y are returned from an lm(...) call): legend("topleft", legend = c(bquote(R^2 == .(summary(x)$r.squared)), bquote(R^2 == .(summary(y)$r.squared))), fill =

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 have a plot containing a large number of lines. I have placed a legend in the plot, but with so many lines, the legend takes up a lot of space. I have tried to reduce the spacing between the lines using the legend parameter x.intersp=0.7, but this does not compress the legend enough. Is there some way to make the text font size smaller in "legend"? Thanks, RH.

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

Hello, I am trying to include legend text with math symbols from a predefined character variable that is read in from a file. ? If there is only one line of text in the legend, the following, although cumbersome, works for me: ? > LegendText = " 'U' [infinity], '=10 m/s' "?? # (read in from a file) ??> LegendName = paste("bquote(paste(",LegendText,

Hi All, I produced a barplot and made a horizontal legend below the graph. Because the results are from a survey, there are three levels, namely strongly disagree/disagree, neutral and strongly agree/agree. > rownames(survey)[1] "Strongly disagree/disagree" "Neutral" "Strongly agree/agree" As in the output above, there is a large space

Hello, I need to reduce the size of the text in a legend since the legend is overlapping with the curves in my plot. I've not been able to identify any way to achieve this in the documentation. Anyone have any suggestions on how to scale down the text or the overall legend? Thanks in advance for your help! Chris Diehl [[alternative HTML version deleted]]

Hello, I'm trying to add a symbol (Delta) to plot legend with text using "expression(paste())" but this disables the text.font that allows to use bold or italic text. as follows: x=c(1:10) y=c(1:10) plot(x,y) legend(1,10,legend=c("A","B","C",expression(paste(Delta, D))), pch=c(24,18,17,16),cex=2,text.font=3,bty="n") Any suggestion to

Hi, When I place a legend on a plot it looks exactly as I intended on the screen. However, almost always, when I export this to postscript file, the legend's text protrudes through the legend's frame (the latter being placed correctly). See the appended example code. I can send the EPS file as well for those that are interested (<4 kb; <200 lines). I found nothing in the FAQS,
