Hi, I am making myself familiar with ggplot2 (I really like the examples at <http://had.co.nz/ggplot2/>). One thing that really annoys me is the default use of white grid lines and a gray background [1, 2]. I simply would like to have black grid lines and a white background. No problem, I thought, "This is R. There is no if. Only how." (fortune("Simon Blomberg")).

Hi, I am having some hard time figuring how to access (and modify) the properties of an object created by ggplot. I found 'ggopts', but it only returns some of the properties. Say I want to get the x- and y-axis limits, the tickmark locations, legend current position, the legend box and background color and set them to new values. Are these properties easily accessible (and modifiable) from the object? Here is an examp...

Hi all, I prepared a few charts with ggplot2, and was happy with the results as displayed on screen. I tried to draw them with a PNG driver instead. But I ran into several problems while trying to increase the resolution of the picture. Mainly, when I increased the picture size (e.g png(width=1024, height=768) ), the texts (title, labels, etc...) where too small. I tried to set the

Hi I am using ggplot with the aesthetic=list(..., colour=x, ...) ggplot() ggline() I have four different values in x ("ren", "cyn", "mixed", "bare") and I have two questions 1) I would like to assign specific colours to the values, i.e. green, red, blue and brown. How can I do this? I did not understand map_colour_brewer. 2) I don't want the

Is there a way to control the aspect ratio of plots using ggplot? Specifically, I'm using the formula=a~b argument to produce a grid of plots, but the overall width of the result seems to vary for reasons that are obscure to me. This affects not only the appearance of the plots but the amount of space available for the title (which seems to be right justified relative to the right edge of the

Hi I am using ggplot2 at the moment and I must say it is definitely better then ggplot - good work. My problem is that I am using facet_grid() in the following way: > p <- ggplot(ssq, aes(x=year, y=-log(ssq))) > p + geom_point() + facet_grid(me*gi~cs*rz) and it works nicely, except that I would like to have, in naddition to the values of me, gi, cs and rz the name of the variable.

Hi, I am an R beginner and wish to create some 3d plots. I have managed to install the rgl library and save 3d plots, but only as an R file. I wish to use rgl.snapshot so I can create a ".png" file and the plot can be used in LaTex. The function rgl.snapshot does not work (i get an error "failed" message). Having looked at previous posts, I believe that the problem can sorted

How do I change the font size in the facet labels along the edges of the plot? For example (from the ggplot help file): p<-ggplot(tips, sex ~ smoker, aesthetics=list(x=tip/total_bill)) gghistogram(p) In this plot, the facet labels are "smoker: No", "smoker: Yes", "sex: Female", "sex: Male". What command can I use to reduce the font size of

Hi all! I would like to import a matlab or gauss code to R. Could you help me?

I want to take the first row of each unique ID value from a data frame. For instance > ddTable <- data.frame(Id=c(1,1,2,2),name=c("Paul","Joe","Bob","Larry")) I want a dataset that is Id Name 1 Paul 2 Bob > unique(ddTable) Will give me all 4 rows, and > unique(ddTable$Id) Will give me c(1,2), but not accompanied by the name column.
