prop.test vs hand calculated confidence interval
Hi,
This code:
n=40
x=17
phat=x/n
SE=sqrt(phat*(1-phat)/n)
zstar=qnorm(0.995)
E=zstar*SE
phat+c(-E,E)
Gives this result:
[1] 0.2236668 0.6263332
The TI Graphing calculator gives the same result.
Whereas this test:
prop.test(x,n,conf.level=0.99,correct=FALSE)
Give this result:
0.2489036 0.6224374
I'm wondering why there is a difference.
D.

Two 3D cones in one graph
Dear R-users:
The following code produces two cones in two panels. What I would like
to have is to have them in one, and to meet in the origin. Does anyone
have any good ideas how to do this?
Thanks for your help

automatically adjusting axis limits
Dear R users,
I am a newbie. Just switched from MATLAB. So thanks a lot for your
patience.
I have 50000 spectra collected in field. Each spectra has two columns :
Wavelength (56) and the actual measurement.
Each measurement came in a different .txt file on disk (50000 files in
total). I wrote a script that reads every spectra in a for loop and
constructs two variables :
Wavelength (56) and

Printing localized pdf file from Sweave snippets
Hello!
I am struggling for quite some time with proper printing of local
characters in pdf plot, via Sweave snippets in Rnw file.
When I am working directly within R, all is fine and I can get local
character properly, like:

matplot.Date & matplot.POSIXct
Hello, All:
????? Roughly a decade ago, I added "matplot.Date" and
"matplot.POSIXct" to the "fda" package, so we could get reasonable
labeling of the horizontal axis when "x" was class "Date" or "POSIXct".?
I also added a local version of "matplot.default" that just changes the
defaults for "xlab" and

Matplot does not work with x being POSIXt class (PR#9412)
Hi,
Matplot works with x being Date class but not POSIXt. Here is the
example with R version 2.5.0 Under development (unstable) (2006-12-06
r40129)
Example:
x <- Sys.Date() - c(1:10)
y <- cbind(1:10, 10:1)
class(x)
## [1] "Date"
matplot(x, y)
x <- strptime(as.character(x), format="%Y-%m-%d")
## [1] "POSIXt" "POSIXlt"

plot matrix
Dear R users,
I like to plot a matrix A which looks like this:
,1 ,2 ,3 ,4
1, 1 10 100 1000
2, 0.5 0.2 1.0 4.3
3, 0.1 0.2 0.3 0.5

where the 1st row is representing the X-axis values. The subsequent
rows should be plotted on the y-axis. I would prefer to use the
smoothScatter plotting function of the geneplotter package, but to
begin with R I'd be happy to use

How to fix error: 'x' and 'y' lengths differ
Hi, im a student so still very new to R. Hope someone could help me out here
=)
They are 3 slug control products, bustaslug, product X and Y. Im ask to
explore the data by plot() and tapply(). But when i try to plot or use the
tapply command, it tells me that the x and y lengths differ. so im thinking
its because the data is unbalanced? Is there a simple command that i could
use to fix this?

'matplot' for matrix with NAs: broken lines
Hi list,
I know that points involving NAs are not plotted in 'matplot', but when I plot them as lines, I still want the lines to connect all the points (i.e. not broken where there are NAs).? Please see the example below.? How can I achieve this in 'matplot'?? If I can't, any good alternatives so I don't have to use 'plot' + 'lines' and loop through all the

Can one set box line width within the matplot command?
Hello R users --
I am using matplot to prepare graphs and cannot find a way to use (for
example) box(lwd=3) within the matplot command and instead have been
setting the box line width after drawing the graph, by using box(lwd =
3). Looking over the ?par options and the matplot() help I do not see a
way to set box width within matplot. Is there such an option?
Thanks for suggestions,

Help with matplot
Hi, I apologise in advance for the na?ve question. I have large matrices that I want to plot. I currently use color2D.matplot. However, these matrices contain many values of no interest (i.e. where there is no data, the figure -999 is automatically displayed). Is there any way of removing these from the matrices to be plotted by matplot? An obvious possibility is setting them all to 0, but that

I finally came up with a nice colored matrixplot, using the color2D.matplot

Here's what I do:

inconsistent matplot behaviour?
I raised this question quite some time ago but it quitly went down the
river. I'll give it a second try (before keeping my modified version of
matplot for ever...):
matplot supports vectors (and/or character strings) for a number of
arguments namely `type', `lty', `lwd', `pch', `col', `cex'. all of them
act consistently in such a way that the first entries are used

How to name variables in a single plot
Dear R Friends ,
I want to name my variables( more than 2 variables in a single plot) within a plot to distinct them from each other, but I cann't. How it is possible? I don't mean x and y axis using xlab or ylab. At the below , it follows some lines, only as an example that you could try please, if it is possible. I really thanks for your attention.
