similar to: ggplot2 - expand range?

Dear All, I am trying to build a simple ggplot, but where the scale is reversed, i.e. the largest numbers are on the bottom. An example of the code I am using is > plotdata<-data.frame(x=1:10, y=runif(10)) > plot<-ggplot() > plot<-plot+layer(data=plotdata, mapping=aes_string(x='x',y='y'), geom='point', stat='identity', size=4) >

Dear All (probably Hadley), I am now trying to customise some plots using a bar geom. I do not want to use the default binning statistic, but rather calculate the bar heigths separately. I do manage this, but for comparison purposes I would like to have a set of plots all with the same y-axis height. But I do not seem to find out how to fix the scale of the y-axis in this case. Any tips?

Dear All, After having overcome the issue of legends (thanks, Thierry, once more), I am trying to use facetting, but here also I can not find how to do this. I do not want to use qplot, but rather the more flexible options. However, it seems I am doing still something pretty stupid, because I always get an error, even if it seems I am doing everything like the examples. My code is below.

Dear All, I am trying to build an error bar plot with ggplot2. However, even if the code seems to work, the plot is rather odd, with what seems to be a continuous line linking the different bars. I attach below the code I used, as well as the data. ================================================================ DFrame<-data.frame(x=1:10,y=0.5*(1:10),Upper=(1:10)+0.5, Lower=(1:10)-0.5) p

Hi, I am learning xyplot. I have an example dataset attached. plotdata<-read.table("plotdata.txt",sep='\t',header=T,row.names=1) head(plotdata,n=4) y x type 1 -4.309601 -0.7448405 A 2 -4.715421 0.7875994 A 3 -2.310638 0.5455310 A 4 -2.685803 10.4116868 A xyplot(y~x,groups=type,plotdata, auto.key=T) This shows different colors for different

Hi list, Does any body know how I can create a margin area around the graphic created by xyplot (the same thing we do using par in plot function)? I tried viewport, but does not work. Here is the code: ============================================== require(grid) vp<- viewport(x=.1,y=.1,width=.6,height=.6,just=c("left", "bottom")) pushViewport(vp)

This is really a question of how to program this *BETTER*. It works as I have done it, but is quite ugly. I want to do a 3d scatterplot of the upper triangle of a matrix, where the z-values are the values in the matrix, and the row and column indices are the y- and x-values. The complete (11 by 11) matrix is mmtop94.2. Here is my awkward code: mmtop94.2[lower.tri(mmtop94.2)] <- NA # Here i

Hello everyone. I am using ggplot and I need some help to merge these two plots into one. plot_CR<-function(x,y,agentid,CRagent){   library(ggplot2)     agent<-CRagent[[agentid]] # To make following expression shorter   ggplot((data.frame(x=CRX,y=CRY,sr=agent$sr)))+   geom_point(aes(x,y,colour=cut(sr,c(0,-10,-20,-30,-40,-50,-60,-70,-80))))+   geom_text(aes(x,y,color=cut(sr,

Dear all, today I have writted the following code, to plot the contents of some matrices I have plot_shad_f function(f){ library(ggplot2) dev.new() plotdata<-melt(f) names(plotdata)<-c('x','y','z') v<-ggplot(plotdata, aes(x, y, z = z)) print(v + geom_tile(aes(fill=z))) } I would like to ask your help add a small circle in this plotting. What would be

I am trying to plot some data, but have got some difficulties with labels on the tick marks on the x-axes. There are 20 data points. All I want to do is to plot the Loss versus Lines. When I use xyplot, the first tick mark starts from 2 rather than 1, and also there is a NA as the final tick mark. Here is the R code you code give it a try: Would any body be able to fix this, please?

Hi all, I've been trying (unsuccessfully) to modify an xyplot I created using the lattice package. I would like to change default strip colors and locations. I started with numeric data in 4 columns, which look like this: 0.25 2 1 32 0.25 2 2 30 0.25 2 3 27 0.25 2 4 23 0.25 2 5 17 0.25 3 1 30 0.25

Hello R help mailing list, I'm having difficulty saving a series of figures in an analysis. I have attempted to save them in a for loop with the following code: for(i in 1:20){ sF<-paste("fig",i,".jpeg",sep="") jpeg(file=sF,width=600,height=500,quality=100,pointsize=12) attach(plotData) xyplot(CHC~1:13), detach(plotData) graphics.off() } If I break

Dear all, I am basically a GIS user and am new to R. I am trying to write a data frame to a dbf file. *n.simulations <- 999 binomial <- kulldorff(geo, cases, population, NULL, pop.upper.bound, n.simulations, alpha.level, plot) cluster <- binomial$most.likely.cluster$location.IDs.included df <- data.frame(ID=seq(1,n.simulations,by=1), simloglkhd=binomial$simulated.log.lkhd)

Dear List I am trying to draw a heatmap using ggplot2. In this heatmap I have faceted my data by 'infection' of which I have four. These four infections break down into two types and I would like to reorder the 'infection' column of my data to reflect this. Toy example below: library(ggplot2) # test data for ggplot reordering genes <- (rep (c(rep('a',4),

Is there a canonical means to apply a function over multiple arrays simultaneously? For example, if I wanted to plot each line with a different color? Or is a for loop conversion my best option? x <- seq(0, 8, by = 2) y <- matrix(1:15, nrow = 5, byrow = TRUE) my.colors <- heat.colors(3) drawLines <- function(row) { lines(x, row) # want corresponding 'my.colors' here }

Is the pictex graphics device known not to support color? In R 2.0.1 Patched (2004-11-17), it produced very pretty output: ## pictex(file = "modern-metatheonomy.tex", bg = "transparent"); ## plotData(data); ## dev.off() ... but it appears to have ignored all color information. __________ Steve Rowley <steve.rowley at sanofi-aventis.com> Cambridge, MA: (617) 768-4054

Dear All, I am trying to build a stacked bar plot, where I define the colours to use. I have asked this before, and I was using a solution in http://thread.gmane.org/gmane.comp.lang.r.general/100649/focus=100673 (thanks, Thierry). However, it looks this works only when the data are in the sequence of the levels in the factor defining the fill colours. When the sequence is different, the

Hi list, In the following code, how can I place the percentage label away from numbers in the second y-axis (lets say all should be inside plot area)? Thanks Alireza ================= require(grid) vp<- viewport(x=.1,y=.1,width=.6,height=.6,just=c("left", "bottom")) pushViewport(vp)

Hola de nuevo. Resulta que al actualizar a la versión 0.9.2 de ggplot2 , ahora en mi eje continuo y , los valores se etiquetan en formato científico , cuando antes era normal. Es decir, mis valores máximos están sobre 300000, pero en el eje ahora pone 3e+05 y no he encontrado como cambiarlo. He visto que se puede cambiar utilizando el paquete scales y utilizando por ejemplo , siendo p un

Hello, this following code give a nice png: /library(ggplot2) i <- 1 png(file=paste('test ',i,'.png',sep='')) qplot(carat, data=diamonds, fill=color,geom='histogram')+scale_y_continuous(i) dev.off() / I would like to get more files, but the following code doesn't make any file: /library(ggplot2) for (i in 1:2) { png(file=paste('test
