Just as an exercise I am tying to add colours to a geom_segment command. I can get one colour but not a sequence of colours. Can anyone suggest how I can get the green lines in the plot below to be different colours? I thought I could use a palatte of colours but that did not seem to work. Thanks ========================================================...

Dear R users, The following issue has been already documented, but, if I am not mistaken, not yet solved. This issue appears while trying to plot arrows with "geom_segment" (package ggplot2), with polar coordinates ("coord_polar"). The direction of some arrows is wrong (red rectangle). Please find herewith an example. Does someone know how to deal with that issue? Best Regards, Pascal Oettli #--------------------------------------------------...

...ple: df <- data.frame(cat=LETTERS[1:4],num=rnorm(4)) ggplot(df, aes(x=cat, y=num)) + geom_point() + geom_line(aes(x=as.numeric(cat), y=num)) In this plot, I would like to be able to make the second line (the one between B and C) not be there. What I've come up with is this (instead using geom_segment): df <- data.frame(cat=LETTERS[1:4],num=rnorm(4)) dfdf <-cbind(df[seq(from=1,by=2,along.with=df),],df[seq(from=2,by=2,along.with=df),]) names(dfdf) <- c("cat","num","cat2","num2") ggplot(df, aes(x=cat, y=num)) + geom_point() + geom_segment(aes(...

Hi, My example code is this; x11<-data.frame(A=c(.6,.6,.6),B=c(.20,.20,.20),C=c(0.20,.20,.20)) ggtern(data=x11,aes(A,B,C,xend = c(0.7,.00,0.7),yend = c(.30,.50,.0),zend =c(.0,.50,0.3)))+ geom_point()+ theme_showarrows()+geom_segment(size=.5)+ geom_text_viewport(x=c(.45,.27,.37),y=c(.32,.29,.22),label=as.expression("P_a","P_b","P_c")) ggtern(data=x11,aes(A,B,C,xend = c(0.7,.00,0.7),yend = c(.30,.50,.0),zend =c(.0,.50,0.3)))+ geom_point()+ theme_showarrows()+geom_segment(size=.5)+...

reading ?plotmath you might notice that "_" isn't the propper syntax for subscripts. This will work: ggtern(data=x11,aes(A,B,C,xend = c(0.7,.00,0.7),yend = c(.30,.50,.0),zend =c(.0,.50,0.3)))+ geom_point()+ theme_showarrows()+geom_segment(size=.5)+ geom_text_viewport(x=c(.45,.27,.37),y=c(.32,.29,.22),label=c("P[a]","P[b]","P[c]"), parse=TRUE) cheers.

Hello everyone (and Hadley in particular), I often need to plot data from multiple datasets on the same graph. A common example is when mapping some values: I want to plot the underlying map and then add the points. I currently do it with base graphics, by recording the maximum region in which my map+point will fit, plotting both with these xlim and ylim parameters, adding par (new=T)

I'm doing a path plot with ggplot2, the result is looking very nice, but I want to give some indication of which direction the lines are going. I thought of using colour gradients, but it doesn't look right. What would be ideal is a line type that indicated direction, something like ">>>>>>>". Is there any way to achieve this? Or can anyone suggest another

Hi, I am trying to add a vertical arrow (from top to bottom or from bottom to up) to a time series plot using ggplot2 and xts. It seems that the vertical line command "geom_vline" does not work for this purpose (Correct me if I am wrong). I try the command "geom_segment" as follows, but I got an error message at the last line "Error: Invalid input: date_trans works with objects of class Date only". Sometimes the error message occurs when I run the program, sometimes it does not occur until I call the plot "p1". How could I add a v...

Hello, I am drawing contour lines for a function of 2 variables at one level of the value of the function and want to include a small arrow in any direction of increase of the function. Is there some way to do that? Below is an example that creates the contour lines. How do I add one small arrow on each line in the direction of increase of the function (at some central point of the contour

Is there a package in R that can do a variability plot? A variability plot is a kind of categorized dot plot. (If there is a lot of data in each category, box plots are used rather than dot plots.) Usually, the categories are factor level combinations. All the dot plots appear in the same window; below the x-axis a hierarchy of factors shows which dot plot corresponds to which factor-level

Cordial saludo. Estoy tratando de hacer un gráfico con qplot de la libreria ggplot2, en ella tengo dos vectores un "x" y un "y" de tal forma que el gráfico seria qlot(x,y...), ahora quiero añadir un nuevo gráfico con un vector "y1" pero en el mismo cuadro algo parecido a lo que hace la funcion "lines", es decir, que en en mismo cuadro me queden las dos

Hi, I would like to use xyplot to create a figure. Unfortunately, I cannot find documentation in xyplot to specify alternating the x-axis tick labels with the x-axis tick marks. I can do this with the regular R plot function as follows. #A small version of my data looks like this data<-data.frame(matrix(ncol=3,nrow=12)) data[,1]<-rep(c(1,2,3),c(4,4,4)) data[,2]<-rep(c(1,2,3,4),3)
