Legend placement in barplot?
This has been asked before, but all the answers are hidiously complex.
The
legend.text=TRUE
option of barplot is almost exactly what I need, except I need a
legend.placement='tl'
(top left) option. This option would be in contrast to the default
placement which we could call 'tr' (top right).
Anyone know how to edit the barplot code to make this change? Could

R Graph Gallery : categorization of the graphs
Hello all,
It seems that the next improvement to the R Graph Gallery is
categorization of the graphics, that way each graph will be easier to
find. That step should be done *carefully* if we want to avoid the
opposite side-effect : graph not reachable through the categories.
That's why the wisdom of the R community is required.
Graphics will be classified in :
- categories

highly biased PCA data?
Hello, supposing that I have two or three clear categories for my data,
lets say pet preferece across fish, cat, dog. Lets say most people rate
their preference as being mostly one of the categories.
I want to do pca on the data to see three 'groups' of people, one group
for fish, one for cat and one for dog. I would like to see the odd person
who likes both or all three in the

hist function to give each cell equal area
Hi,
I want to use hist with non-equi-spaced breaks, picked such that the
fraction of the data points falling in the cells (defined by 'breaks') is
roughly equal accross all cells.
Is there such a function that will automatically try to determine the
breaks to fullfill this requirement?
Something like..
hist( x, br = magic_function_to_pick_breaks())
For example, if x looked like

Adding values to the end of a vector?
I want to add values onto the end of a vector, for example...
x <- vector
for (i in 1:5){
add_to_end_of_vector(i,x)
}
I just cant find the answer to this question!
Sorry for such a basic question, I tried...
x <- c()
for (i in 1:5) x[length(x)] <- i
but it didn't work.

barplot and ylim - display problems
The following single line of code shows what I am trying to do, and the
problem I am having...
barplot(c(101,102,103),ylim=c(100,103))
The 'xaxis' is missing, and the grey bars 'fall off' the plot area. This
is generally ugly, and I would like to trim the bars (ideally they would
have a ragged appearance to show that I am 'zooming in').
I can see why what I am trying to

Retrieve part of (top right corner) of a "plot.data.frame" plot?
Hi,
I believe this question has been asked before, but I cant find and don't
remember the answer.
The problem is simple, calling 'plot.data.frame(x)' gives a nice 'matrix of
scatterplots' for each pair of columns in x. for example;
x <-
data.frame(a=jitter(01:20),
b=jitter(20:01),
c=jitter(21:40),
d=jitter(rep(01,20)),

data(eurodist) and PCA ??
If I perform PCA on the 'eurodist' data, should I get an accurate
geographic layout of the cities with biplot?
(barring inversions, i.e. their is no way to define north.. but you get
the idea...)
I have a complex distance matrix, and I am thinking about how to cluster
it and how to visualize the quality of the resulting clusters.
If I could 'see' the clusters in space I could

Plotting FAQ?
Hi,
Since I started to make some 'final' plots of my data I found that I
have tons of questions related to 'the little things'. Rather than
bother the list with all the questions (ahem), or search the archives
for similar questions and translate the context, I would like to find a
FAQ for plotting in particular (and R programming in general). I know

R-(wiki)-pedia?
Is there an R wiki?
Looking at the huge amount of traffic on this list, I think wiki could be
an exelet outlet for all the constructive enthusiasm here.
I don't think it would be too hard to port the existing R documentation
(the stuff you get with the ?) onto a wiki system, then users could add
their own examples and comments.
Having distinct web page style organization would be easier to

plot.default and open ended limits
Hi, I would like to bound the lower limit of my y scale to zero, and let R
chose an upper limit.
Something like
plot(x,ylim=c(0,))
or
plot(x,ylim=c(0,na))
but nither of these do the job. I searched the docs, but I can't see a way
to do this.
Naturally its nothing I can't do 'by hand', I would just like to know if a
correct syntax exists.

Setting the xlab for 'the other' (upper) X axis?
I would like to set the 'xlab' on the 'upper' x axis. The following code
shows roughly what I want by way of (one possible) expected behaviour.
par(mar=c(5.1, 4.1, 5.1, 2.1))
plot(rnorm(10), rnorm(10), xlab="the lower one")
axis(3, xlab="the upper one????")
There are various other ways that could be expected to work, but hopefully
the above is clear enough to
