thus how do I get raw data
(object ab) from ddd?
I've tried
as.data.frame.table(ddd)
which is not the answer I'm looking for.
Thanks in advance,

dear all,
here's a couple of questions that puzzled me in these last hours:
# issue 1 qnorm(1-10e-100)!=qnorm(10e-100)
qnorm(1-1e-10) == -qnorm(1e-10)
# turns on to be FALSE. Ok I'm not a computer scientist but,
# but I had a look at the R inferno so I write:
all.equal(qnorm(1-1e-10) ,
Hi Danny,
it sounds to much easer than that.
Try
y - data.frame(matrix(rnorm(100),10))
nr - ncol(y)
test - lapply(y, shapiro.test)
sapply(test,function(x)c(x$statistic, x$p.value))
it should perform the required task.
Cheers,
P

many thanks for your very useful suggestions.

zoom in a square box. Is there any way to produce rectangular ones?

dear all,
I'm a newbie in map tools. I was asking to perform an apparently very
simple task.
I have a list of countries (about fifty all over in the world) scored
with a real positive value. Eg
Country score
Italy .56
UK .58
Korea .41
Mexico .63
...
I wish to plot geographical maps
or the exactly equivalent form:
x[x$X1 %in% unique(x[x$X20,X1]), ]

James,
as I previously told you in my broken English, probably the function
you're looking for is not filled.contour but image and contour
The following code makes exactly what you ask for
data(akima)
akima
akima.smooth -
with(akima, interp(x, y, z, xo=seq(0,25, length=500),
James,
you're probably interested in image function rather than in
filled.contour. Type ?image to see the syntax.
Cheers,

dear Silvia,
quoting Venables WN and Ripley DB (1994) Modern Applied Statistics
with S-plus, sringer, pag 185:
Since explicit expressions for the maximum likelihood estimators are
not usually available estimates MUST be calculate iteratively
means that glm.fit performs MLE indirectly and
try this
colSums(matrix(x,8))
