Dear list, I am new with ggplot2 and I have spend quiet some time putting together the following code to create the attached plot. However there's still a few things that I'm having trouble with! I would be grateful if someone can tell me how to fix (1) the colour of my bars into grey scales (2) removing the y-axis (species name) on the right figure to avoid duplication, and (3) fix the

Hello, I am trying to plot means and standard errors conditioned by a factor, using qplot. I am successful at getting the bar graph I want with a error bar, however I have tried many things and cannot get the bars to change colors. Currently showing as red and blue, but need it to be black and white for publication. Any suggestions please? Using a data set June, which is str:

Hello, I'd like to sitch to a monochrome/bw color-palette for the filling of geom_bar-bars (produced via "qplot" as in the example below). Hours of googling didn't yield anything useful, so I thought, I'd just ask ... Thanks, Joh library(ggplot2) qplot(factor(cyl), data=mtcars, geom="bar", fill=factor(cyl))

Am trying to produce a graph which prints out well in black and white using ggplot2. I have the following example set up nicely, but want to shade the red bars in one pattern and the blue in another so they print out clearly. I tried changing colours to 1 light, 1 dark, but then the overlapping colour looks virtually identical to the darker one. I noted the option density in barplot, but

I've just used r a little, so this might be a trivial question but I have a small data file part, vs/total ,ps/total, gpgpu, date ... ... ... ... .. that contains the percent that certain features contribute to a part and the date the part was built I'd like to do stacked bar graphs one bar per part showing the

Hello Folks, I have a database of 2000+ days with 35 observations each. I am trying to modeling a time series by day, but it seems a problem that I don<t have the time of the observation. I achieve something interesting by using the barplot function, but I`d rather working with ggplot2, since I have the book by Hadley Wickham in hands. I start by transforming my data into a dataframe, but
