lattice: option to sort x when type = l
Hi,
(please Cc me)
In xyplot (), type = "l" (or one that includes "l", *el*) is
(generally) meaningful only when the 'x' variable is sorted. In
practice, one either sorts the data frame before hand or writes a tiny
panel function which sorts the supplied x and then calls the default
panel.xyplot(). Trouble arises when there is a conditional variable as
well as a

Recently, I ran rsync and got the following message:

It turns out that the file in question is really a degenerate link

[RFC][PATCH 1/2] Btrfs: try to allocate new chunks with degenerated profile
If there is no free space, the free space allocator will try to get space from
the block group with the degenerated profile. For example, if there is no free
space in the RAID1 block groups, the allocator will try to allocate space from
the DUP block groups. And besides that, the space reservation has the similar
behaviour: if there is no enough space in the space cache to reserve, it will

is this trellis device or standard graphics device?
OK, here is the issue:
I have a graphcis device (say X11) which I can set as active by
dev.set(n). Is there ANY way to identify/infer whether this X11 device
was obtained from a lattice function (like xyplot, levelplot...) or a
standard function (like plot, scatterplot,...).
A related question is whether plot.new (or frame) was called to obtain
this graphics device...
Thanks.

RWeka - Error when attempting to summary() model
I'm a big fan of both Weka and R (quite new at R :) ), and jumped at the chance to use them together. Unfortunately, I'm running into what is probably a dumb error when trying to view info about my model. A Google search turned up 0 hits for the actual error I got (last line), but you all are smarter!

new ogg-tools module in cvs

How to determine the quantile boundary from an ECDF?
Given a dataset x, the ecdf is ecdf(x). Then I can use ecdf(x)(y) to find
the percentile of y. Given the ecdf is there a way to determine what is the
value of y that is the boundary of let's say 95 percentile? In other words,
is there a function I can call on the ecdf like:
fomeFunc( ecdf( x ), 0.95 )
Which will return the highest value of y, for which ecdf( y ) < 0.95?

Two ecdf with log-scales
Hi,
i want to plot empirical cumulative density functions for two variables in
one plot. For better visualizing the differences in the two cumulative curves I'd like to log-scale the axis.
So far I found 3 possible functions to plot ecdf:
1) ecdf() from the package 'stats'. I don't know how to successfully set the log.scales? Combining two plots is not a problem:

ECDF values
Dear UseRs,
maybe is a silly question: how can I get Empirical CDF
values from an object created with ecdf()?? Using
print I obtain:

Thanks in advance.

lines, ecdf and colors

different colors. I can plot using the same color, but it doesn't

Absolute cumulative curve with ecdf/stepfun?
Hi,
I have two variables ranging both from 0 to 1 (n=500 each).
Now I am interested in plotting them both in one plot (using ggplot2).
So far I used ecdf() (from an example I found with google) to get
values for the cumulatice distribution function which gives a relative
curve. I also want to do the same plot but using absolute cumulative
values instead of relative. Can that be done with ecdf or

Plot 2 ecdf in one graph
Hi r-users,
I would like to compare the cdf between historical and predicted. My x.obs and x.pre are the frequency data in classes of 0-300.
I tried:

and it gives me:
Error in plot.stepfun(x, ..., ylab = ylab, verticals = verticals, pch = pch) :

Confusion about ecdf
Hi,
I'm bit confused about ecdf (read the help files but still not sure about
this). I have an analytical expression for the pdf, but want to get the
empirical cdf. How do I use this analytical expression with ecdf?
If this helps make it concrete, the pdf is:
f(u) = \sum_{t = 1}^T 1/n_t \sum_{i = 1}^{n_t} 1/w K((u - u_{it})/w)
where K = kernel density estimator, w = weights, and u_{it} =

How to count from larger value to smaller value in ecdf (Empirical Cumulative Distribution Function)
Hi, all
ecdf function (Empirical Cumulative Distribution Function) in "stats"
package counts from smaller values to larger values.
However, I want to draw it by counting from larger value to smaller values
and I couldn't find options for this purpose.
How can I draw ecdf or ecdf like graph by counting from larger values to
smaller values.
Thank you in advance.

Function from ecdf to ccdf
Dear all,
I would like to calculate the complementary cumulative distribution function. As it is known, the ccdf is the 1-ecdf(X)==1-F(x). (From ?ecdf help is shown that ecdf returns a function which is the F(x)
I would like to use that function inside my function and after call curve (which accepts function as input). My code looks like that
