inverse cumulative distribution
hi all:
ecdf() is the empirical cumulative distribution function, but I need the
INVERSE cumulative distribution.
how can I calculate it?
thank you in advance

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

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.

Extracting values from a ecdf (empirical cumulative distribution function) curve
Hi R users,
I am a new user, still learning basics of R. Is there anyway to extract y
(or x) value for a known x (or y) value from ecdf (empirical cumulative
distribution function) curve?
Thanks in advance.

Empirical cumulative distribution with censored data
Dear list,
I would like to plot the empirical cumulative distribution of the time
needed by a treatment to attain a certain goal. A number of
experiments is run with a strict time limit. In some experiments the
goal is attained before the time limit, in other experiments time
expires before the goal is attained. The situation is very similar to
survivial analysis with censored data. I tryed

Cumulative Density Plots (Hmisc/lattice)
I have been using the ECDF function in the Hmisc package to produce
cumulative distribution function plots. The problem is that for small
datasets the steps "look bad" (not my characterization but from the
client). Is there a way to get the same information but smoothed? I have
tried the densityplot (lattice), which gives a smoothed line, but this
does not give the cumulative density.

cumulative distribution functions
hi y'all,
I am wondering if there is any special command, function,
package, etc to help me doing a cumulative distribution function,
with y-scale - probability scale.
I tried the help in R and i got the following answers:

Does R have an "inverse empirical cumulative distribution" function ?
Dear R Users,
Does R have an "inverse empirical cumulative distribution" function,
something one can use to invert ecdf ?
Thanks in advance,

Strange tick in ggplot geom_area; and ordering, again
In the area plots below, I see 4 triangle ticks at both sides of the bar; I
believe these are non-stacked values for p, but they are definitively
confusing.
In addition, I would like to get the order of the colors in the plot the
same as in the legend, and not arranged alphabetically (the factor is
ordered, don't touch my order). Hadley once mentioned an undocumented

ggplot2 - boxplot of variables / columns
Hi,
ggplot/qplot is great - it has really helped me do some nice things.
However, simple boxplot of different columns/variables is a bit
tricky, because of (i think) qplot's generic Y conditional on X input
form. Se below.
# Some data:
a <- rnorm(100)
b <- rnorm(100,1,2)
c <- rnorm(100,2,0.5)
# normal boxplot of a,b,c
boxplot(a,b,c) # Looks good
library(ggplot2) # loads qqplot2

jpeg() creating empty files with qplot() in a loop
Hello all,
I'm stuck with a strange issue with writing jpegs of plots to a folder
in a loop.
This works:
for (step in 1:length(steps)) {
jpeg(filename=paste("frame_",sprintf("%05d",step),".jpg",sep=""))
plot(steps[[step]])
dev.off()
}
But if I use qplot to generate the plot (which is my aim):

plotting a function with given formula in ggplot2
Hi All,
I have a scatter plot produced using ggplot2 and I want to add the
regression line to this scatter plot. I suppose I can use
geom_smooth() to do this, but for the sake of learning ( I am new both
to R and ggplot2), I want to try and add it as a function (something
that curve() does in the standard R plotting). I did some search and
found that stat_function() can be used for this. But

ggplot2 stacked bar - sum of values rather than count
Hi,
I'm trying to create a stacked bar plot using ggplot2. Rather than
plotting the count of each of the 13 "Bar" factors on the Y axis, I
would like to represent the sum of the Values associated with each of
the 13 "Bar" factors. Is there a way to do that? Given the following
data, that would obviously mean that there would be some negative sums
represented. Here's

Cumulative density (kernel smoothing)
Hi, in R there is the function "density" which computes kernel density
estimates. Is there a "cumulative" version of it? Something like they have
in Matlab:

I know there is ecdf, but I'm not sure it's based on kernel density
smoothing. Thanks
