similar to: ggplot2: How to export several plots with same width?

Given an arbitrary data frame, it is easy to exclude a column given its index: df[,-2]. How to do the same thing given the column name? A naive attempt df[,-"name"] did not work :)

Searching the mail archives I found that using legend.position as in p.ring.3 + opts(legend.position="top") is a known bug. I tried doing p.ring.3 + opts(legend.position=c(0.8, 0.2)) which works, but the legend background is transparent, i.e. I see the plot background through the legend. Adding additional option opts(legend.background=theme_rect(fill=TRUE,colour="white"))

I have a following problem: The call qplot(wg, v.realtime, data=df.best.medians$gv1, colour=sp, geom="boxplot") works nice: for each value of the wg factor I get two box-plots (two levels in the sp factor) in different colours, side-by-side, centered at the wg x-axis. However, I want to separate the data belonging to different levels of the n factor, so I add the facets option:

Dear All, Perhaps, what I am asking is impossible, but I am asking it anyway. I have got several pdf files with rows of colored rectangles: red rectangles should be read as 0; green rectangles as 1. No other color exists. Is there some way to have R reading the colored rectangles to a matrix or data frame converting the color of the rectangles to sequences of 01? Thanks in advance, Paul

I have a large data-frame with measurements such as: id i v1 v2 v3 1 1 1.1 1.2 1.3 1 2 1.4 1.5 1.6 1 3 1.5 1.7 1.8 2 1 2.1 2.2 2.3 2 2 2.7 2.5 2.6 2 3 2.4 2.8 2.9 For each unique value of 'id' (which in the real data-set is a combination of three variables) I want to compute the median of v1 within each group ('i' distinguishes measurements within a group), and copy the

Hello, What would you recommend for producing publication-quality plots with R? Built-in graphics, trellis, ggplot2, or something else? Basic requirements: - I need to draw line-, box-, density-plots, bar-charts and histograms - error bars on bar- and box-plots - easy tiling of multiple plots on a single "page" Basic R plotting with mfrow and mfcol parameters is not satisfactory

I have a data-set that is structured as follows: sp wg n v.realtime v.cputime v.tcputime v.idletime v.nswtch 9 0 1 1 28.61300 28.61 28.6039 0.00000e+00 407 1563 0 1 2 15.20270 30.38 28.5981 9.80523e-01 483 3128 0 1 4 12.50930 50.00 28.6053 1.07877e+01 489 4682 0 1 6 12.10260 72.55

I use the following function to export some figures to .eps: p.eps <- function(p, fname, title = NULL, width, height) { postscript(file=fname, onefile=FALSE, paper="special", width=width, height=height, horizontal=FALSE) print(p + opts(title = title)) dev.off() } Whenever I have a page consisting of *only* figures exported in this way, Acrobat Reader shows them in

Hi, I have a question related to the newest version of ggplot2 (0.9.0). I just updated this morning and from CRAN it looks like the Mac version is the only one at 0.9.0 as of right now. http://cran.r-project.org/web/packages/ggplot2/index.html Anyway, I was in the midst of a project where I was trying to replicate "Back-to-back Bar Charts" in this blog post.

How do I reverse the order of the legend in a bar plot to match order of the x-axis? In other words, I want the stacked colors of the legend to match the stacked colors of the bar plot. I tried this, but it didn't work. colors <- c("5" = "red","4" = "blue","3" = "darkgreen") p <- qplot(factor(cyl), data=mtcars,

Por lo que entiendo, en gradethis si el estudiante se equivoca tiene la posibilidad de reintentar hasta dar con la solución, lo cual no lo
