ggplot2 / reshape / Question on manipulating data
I'm an R newbie but recently discovered the ggplot2 and reshape
packages which seem incredibly useful and much easier to use for a
beginner. Using the data from the IMDB, I'm trying to see how the
average movie rating varies by year. Here is what my data looks like:
> ratings <- read.delim("groomed.list", header = TRUE, sep = "|", comment.char = "")

(no subject)
Hi all,
I am looking for a clever way to create the following graph using R:
I got information on the shares of some subgroups over time (summing up to 1 in each year). The graph I want to create should display the development of the individual shares over time by shading rectangulars for each share in a different color.
Is there a clever of doing this?
Thanks for your help

2d plotting and colours
Hi!
I am new to R just 3 days in it and i apologize if my questions seem very
trivial and consumed your valuable time.
I am coding in perl and i stumbled upon R regarding plotting good
statistical graphs.
I tried the kmean clustering for a large matrix ,say > 150 * 150 . I tried
the example code given in the tutorial to perform 2d plot
# i ranges from 2 to 10
cl <- kmeans(x, i, 20)

Drawing a colour wheel - bug in hcl?
Hi All,
I'm trying trying to draw a colour wheel (a slice of hcl space) in R.
Running the code below doesn't give me what I expect - there's some
oddly bright colours of the wrong hue around c(0, 0) and I see three
coloured circles (a small magenta, a medium sized yellow and a large
cyan). Am I doing something wrong or is there a bug in the hcl code?

barplot default colors
Dear R-help,
Can some one explain why barplot() uses changing colors in the bars by
default? I should think that most of the time when people draw barplots,
they want the bars to be in the same color. (At least that's what I'd
expect. The first time I used barplot() in R, I was shocked to see the
colors.) As an example, one example in ?layout draws a scatterplot with
histograms drawn

Now I feel really smart!
Ok.
I seem to be having some real problems today :)
There is a link from the main page straight to the Wx::Frame tutorial, under

Brewer colours
Anyone who is interested in using optimal colour palettes should
look at the work of Cindy Brewer: www.colorbrewer.org
I have written code to use her colour schemes in R. It is
included below. Perhaps someone may find this interesting enough
to work into a package.
Included also is a function showpalette, which was posted here a
while back. I don't remember who wrote it.

Selecting complementary colours
Dear r-helpers,
I wonder whether, given the "#rrggbb" representation of a colour, there is a
simple way to select the complementary colour, also expressed as a "#rrggbb"
string.
Any suggestions would be appreciated.

white in the default palette
Dear All,
[I'd already sent this message earlier (Apr 6) but as I had no response
and I still see that it is the case in R1.5 I thought I'd try again]
I recently encountered a problem (actually missed some data) because
"white" is one of colours in the "default" palette and that does not
show up to well on my transparent (on white background). Of course it is

displaying intensity through opacity on an image
Dear colleagues,
I have an image which I can display in the greyscale using image. On this image, for some pixels, which I know, I want to display their activity based on a third measure. One way to do that would be to color these differently, and use an opacity measure to display the third measure. An example of what I am trying to do is at:

Lattice package par.settings/trellis.par.settings questions
Hi All,
I'm trying to modify some of the default graphic parameters in a
conditional histogram. While I was able to change the default grey
background to white, I couldn't change the axis.font or the xlab font.
I used the following code:
/histogram(~V751|V013+V025, finalbase, xlab="Heard of HIV/AIDS

Colour palette goes nuts.
Not sure how to describe this or where to point the finger, so I thought I
post here before submitting a bug.

This application is a 'educational' triple CD about Titanic. It is created
with macromedia 'director 6' and utilizes QuickTime.
It installs fine.
Runs fine (needed to disable ddraw on QuickTime) until I try a 'search'.

Recover botched drdb gfs2 setup .
Hi.
The short story... Rush job, never done clustered file systems before,
vlan didn't support multicast. Thus I ended up with drbd working ok
between the two servers but cman / gfs2 not working, resulting in what
was meant to be a drbd primary/primary cluster being a primary/secondary
cluster until the vlan could be fixed with gfs only mounted on the one
server. I got the single server
