Dear all, I am using the code as below   tdm <- melt(matrixToPlot)    p<- ggplot(tdm, aes(x = Var2, y = Var1, fill = factor(value))) +                   labs(x = "Mz", y = "T", fill = "D") +                   geom_raster(alpha=1) +                   scale_fill_discrete(h.start=1) +                   scale_x_continuous(expand = c(0, 0)) +                  

Dear all, I want some help improve my ggplot as following: Make the plottable area with grid, so is easy one to see where each box refers to x and y values. Add a color bar but with fixed values, that I want to specify. How   I can do those two? Before is some code what I have tried so far. Regards Alex

Hello all, I've been using the following qplot command: qplot(pixX,pixY, data=som, geom="tile", fill=rgb) + scale_fill_identity() + opts(aspect.ratio = .75) + facet_grid(unitX ~ unitY) Now I would like to convert it into the explicit ggplot grammar, so I can remove the extras: axes, labels, background, borders, facet labels, and extra white-space around the plot. (If anyone has

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.

Hello, I need plot map using ggplot() I use such code: library("ggplot2") library(cshapes) cshp.data <- cshp() map <- cshp.data[cshp.data$COWCODE==369,] map_mp<- list( geom_polygon(aes(long, lat, group = group), data = map, fill = "grey70", colour = "grey60", inherit.aes = FALSE, show_guide = FALSE), scale_x_continuous("",

R-users it appears I am leaning on your knowledge once again.  Is there any way to add a vertical line to a histogram and qplot "stacked" plot?  Here is my current attempt:   "qplot" approach attempt: qplot(Run, data = data_dataframe, breaks = breaks, fill = Temperature, main = short_title) + scale_x_continuous("Data") + scale_y_continuous("Freq")

Hi, Color of my step plot is now by default. Now I'd like to change the color as the grey scale I specified. I don't know why I got three black plot. Here I attach two version of codes. The first one produces a step plot with color by default. The second one, modified from the first one, is not producing the grey scale I want. Any help would be highly appreciated. [version 1- working]

Dear all, I am using ggplot with geom_tile to print as an image a matrix  I have. My matrix is a squared one of 512*512 cells.  The code that does that is written below > print(v + geom_tile(aes(fill=dB))+ opts(axis.text.x=theme_text(size=20),axis.text.y=theme_text(size=20), axis.title.x=theme_text(size=25) , axis.title.y=theme_text(size=25), legend.title=theme_text(size=25,hjust=-0.4) ,

Dear all, I'm plotting some points on a graph where both axes need to have the same scale. See the example below. Coord_equal does that trick but in this case it wastes a lot of space on the y-axis. Setting the limits of the y-axis myself was no avail. Any suggestions to solve this problem? library(ggplot2) ds <- data.frame(x = runif(1000, min = 0, max = 300000), y = runif(1000, min =

Y bueno, algo más bonito sí que queda con ggplot... #--------------- datIn <- read.csv("pec.csv", header = TRUE, sep = ";", dec = ",") library(ggplot2) lab_x_idx <- c(1, round(nrow(datIn)/2, 0), nrow(datIn)) lab_x <- as.vector(datIn$hora[ lab_x_idx]) fre_gg <- ggplot( datIn, aes( x = 1:nrow(datIn), y = frec)) + geom_bar(stat =

Prueba algo así: library(ggplot2) datos <- read.table("Downloads/pec.csv", header = T, sep = ";", dec = ",") datos$Miles <- as.numeric(gsub("\\.", "", as.character(datos$Miles))) datos$hora <- strptime(datos$hora, format = "%H:%M") ggplot(datos, aes(x = hora, y = Miles)) + geom_line() + scale_x_datetime(date_breaks =

I've been using qplot pretty successfully to generate stacked histograms.  However, it appears that I need to tweak the colors a little.    I've got three temperature variables (characters not numeric) and I need to change from the default qplot colors to the following: Low = Blue Middle = black High = Red   Here is pseudo code of what I have currently:qplot(Run, data = TestData, breaks =

Here is my code, which plots three lines with errorbar. How could I add an extra line without errorbar to the plot? Thank you very much. beta.data <- data.frame ( method = rep(c("Wrong", "Correct", "Full Bayes"), each = T_obs), mean.beta = c(mean.beta1, mean.beta2, mean.beta3), t = rep(points, 3), std.beta = c(std.beta1, std.beta2, std.beta3) ) limits =

I'm running into some problems with the spacing of some faceted ggplot plots. I have a number of time series faceted to be one above another, but the scale labels of the y axes all clobber each other at the bottom/top of each. for example, try: qplot(x, y, data = data.frame(x = 1:10, y = 1:10, size = 1:10), facets = size ~ ., size = size) + scale_x_continuous(breaks = 1:10) +

  Thanks again for the hints about adding the vertical line to the hist plot and in ggplot.  That worked great.    Based on that advice I've been flipping through the ggplot2 doc and ggplot-static\index.html webpage more looking for the answer to the next question.    Unfortunately, I haven't stumbled on a description of how to move around the location of the legend.    Here is what I

I created this graph in ggplot and added ablines to the different facets by specifying with subset commands. As you might see, there are still a few issues. 1.) I would like to have the diamonds in a grey scale instead of colors. I accomplished this (see graph 2) until I overwrote the label title for the treatments and the colors came back (graph 1). I used these two commands: p=ggplot(data =

Hi all, I've this ggplot2 graph (http://www.4shared.com/file/120101043/f3e9350/isotherm.html). I'd like to tweak the legend for the adsorbent part. I'd like to have full square of the colors instead of the full circles. I guess that I've to work on the scale_color_hue or fill somewhere but I haven't found my way yet. Here is my code to get the graph:

Hi List, I am trying to build an animation and facing problem as animation is not coming "live". The goal is to build "heart beats" like diagram for the data given below. data : structure(list(date = 1971:1991, x = c(41L, 60L, 41L, 61L, 22L, 83L, 31L, 55L, 22L, 14L, 38L, 6L, 29L, 17L, 10L, 99L, 88L, 32L, 68L, 78L, 26L)), .Names = c("date", "x"), class =

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 <-

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)
