similar to: ggplot: colours to geom_segments

I am trying to create a simple dot-plot in ggplot2 with a solid line from the y-axis to the dot, something I first saw in Cleveland's 1984 book What I would like is to have the graph start at zero on the x-axis but leave some space on the right side of the plot area. I assumed that I should be able to do this with expand() in scale_x_continuous() but either I'm wrong or just don't

Buenos días, hago un mapa con ggplot: world<-map_data('world') windows();ggplot(legend=FALSE) + ... geom_point(data=Data,aes(x=lon,y=lat,color=Clst),size=1.25) + scale_color_manual(values=c("grey45","navy","skyblue","gold","green3","darkgreen")) + geom_path( data=world, aes(x=long, y=lat,group=group)) + labs(title =

Dear list, I've been using plotmeans {gplots} a lot before, and found the "connect" argument to be quite useful. I've moved to ggplot for several reasons, but would still like to connect lines conditionally, somehow. Is it possible to do? Small example: df <- data.frame(cat=LETTERS[1:4],num=rnorm(4)) ggplot(df, aes(x=cat, y=num)) + geom_point() +

Hola a tod en s, bueno, un poco al hilo de un mensaje anterior, reformulo la pregunta y pongo código completamente reproducible, a ver si hay más suerte. Estoy con un informe y hay que hacer algunos gráficos con datos diferentes con ggplot2, y hay que poner el mismo tamaño para todos ellos. El problema es que R cambia automáticamente el tamaño del área de trazado y el margen en función de

I have just started using ggplot2 and I seem to be doing something stupid in writing ggplot2 commands on more than one line. In the example below the commands on one line are working fine, but as soon as I put them on two lines I get an error. Can any one point out what I am doing wrong? It must be something blindingly simple. Thanks Example

D'oh! Thanks for pointing this out.

Hi, I was trying to get a graph in lattice with the following data frame (7 rows, 5 cols): chr start1 end1 meth positive 1 1 10 20 1.5 y 2 2 12 18 -0.7 n 3 3 22 34 2.0 y 4 1 35 70 3.0 y 5 1 120 140 -1.3 n 6 1 180 190 0.2 y 7 2 220 300 0.4 y I wanted the panels to be organized by 'chr' -

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"))

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)

Hello, I am plotting many histograms together using facet_grid in ggplot2. However, I want to then add a vertical line to each histogram, or facet, each of which vertical lines are at different x-values. The following example adds all vertical lines to each facet: ggplot(data,aes(values)) + geom_histogram() + facet_grid(.~variable) + geom_vline(xintercept=c(5,10,15)) How can I add a vertical

Gracias Emilio y Jorge. Tengo que explicarlo mejor. Mostrando a una audiencia cómo hacer un tipo de análisis, se hace un loop (abajo) que analiza un mapa por regiones longitudinales. Tal y como está el script, print(i) te indica la longitud por la que va (de 10º en 10º) pero me gustaría que en vez de eso te fuese representando una línea vertical sobre el mapa, que he representado previamente con

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

Buenos días ¿sabéis si hay alguna forma de añadir una recta vertical sobre un mapa hecho previamente con ggplot? Lo que hago ahora es cargar nuevamente el mapa con la línea añadida (una serie de líneas añadidas secuencialmente en un loop) pero me gustaría que añadiese las líneas sin cargar nuevamente el mapa. Gracias, Manuel [[alternative HTML version deleted]]

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

Hola, Sí, lo puedes hacer de esta forma... #----------------- set.seed(20) DATOS <- data.frame ( ID = c (1:10) , TIEMPO = sample(1:40, 10, replace=F) , DEF = as.factor(sample(c(0,1), 10, replace=T)) ) library(ggplot2) ggplot( data = DATOS ) + geom_point( aes(x = TIEMPO, y = ID , shape = DEF, color = DEF), size = 5 ) + geom_segment( aes( x = 0, y = ID, xend =

Hi everyone, I am trying to graph a step function in R Studio. I just learned about R today and decided to try it! The following is what I want it to look like. I graphed it using x <- 0:5 y <- c(0, .2, .3, .6, .9, 1.0) plot(x, y, type = "s") And used Microsoft Paint to get it to how I wanted it to look, but I want to do it in R Studio completely.

I am attempting to graph 12 months of temperatures, delineate the months with a vline and place the names of the months at the top of the graph. So far I have gotten everything to work except the names, despite getting a similar graph to work yesterday the day before yesterday with Baptise A's help. Can anyone suggest what I am doing wrong. Data set is below code. Thanks. Code

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)
