what can one do with (to) '..." ?
...have to do a series of 'match' or 'pmatch' on
the output of list(...) , or is there a more direct way to get at the
variables?
If there is a R programmer's manual that discusses this, I'm happy to
read that, so just let me know.
thanks

axis tick colors: only one value allowed?
...r about enhancements to the
plot routines (albeit pretty silly enhancements).
As another side note: calling rug() with color set to '#00000033' lets
you see dense regions as darker than sparse regions, without having to
resort to calling jitter() first.

Looking for the name of a certain kind of quantile plot
...urves for samples
with different sigmas. A sample with nonzero mean looks almost
exponential (or logarithmic, depending on the sign of the mean).
So my question is: is there a name for this sort of plot, and is it of
any real use in statistical analysis?
thanks.

filling the matrix row by row in the order from lower to larger elements
Hello, everybody!
I have a matrix "input" (see example below) - with all unique entries
that are actually unique ranks (i.e., start with 1, no ties).
I want to assign a value of 100 to the first row of the column that
contains the minimum (i.e., value of 1).
Then, I want to assign a value of 100 to the second row of the column
that contains the value of 2, etc.

t() prior to data rotation
Dear All,
I have come upon an R-mode PCA protocol that uses the following arguments,
where "mydata.txt" is an nxm matrix of n objects and m variables:
> a <- read.table("mydata.txt")
> b <- t(a)
> c <- prcomp(b)
> c$rotation
The user then plots the coordinates given by c$rotation (PC1 and PC2) as the
"scores" of their PCA plot.

Image processing and analysis with R
Hello everyone,
I'm working in a project to create an special analysis about visualization in some animals and its behaviour, through checking eye movement. The point is this is very important to get data from the image as a resume of what this animal sees. I think an RGB histogram like photoshop does, but I need to get the data from this histogram analysis and I was wondering about using R

round() and negative digits
...ned in the documentation that negative 'digits' is
allowed, I just wanted to ask whether this behavior is intentional or a
happy turn of events. I'm always paranoid that something not explicitly
documented might disappear in future revisons.

plotting with a symbol on every nth point
Hi,
I would like to produce a plot with a symbol on every nth point in a time
series data, like the one in the following:
http://www.phon.ucl.ac.uk/home/yi/ProsodyPro/EnglishFocus.png
x <- seq(-100,1000,25)
plot(x,type="l")
Could someone help me out with the above example?
Thanks....

place values into a matrix efficiently?
...a raster image of the original data(x vs y) that looks
like plot(x,y) .
Anyway, I just seem to be blanking: is there some vectorized way to
place values, or even a constant value, into all elements of xymat whose
row,col coordinates match ordered pairs in x and y ?

Polygon
Hi everybody,
I have a matrix with 3 columns (Date, MeanArea and SdArea). I want to draw a
figure showing the variable MeanArea in terms of the Date. But instead to
use the variable SdArea as bar error, I want to use ?polygon error?. I use
this code but the output does not seem good.

Detect numerical series
Hello,
I am struggling with detecting successive digits in a numerical series
vector.
Here is an example:
vec <- c(1, 15, 26, 29, 30, 31, 37, 40, 41)
I want to be able to detect 29, 30, 31 and 40, 41.
Then, I would like to delete the successive digits from the vector.
1, 15, 26, 29, 37, 40
Cheers

stupid lm() question
...ontrol?
And if so, what should I do (calculate) with the coefficients to compare
them with the statistics of the data subset with level "A" ?
Please feel free to tell me to shut up and read some part of R-inferno
or other helpful document.
Thanks.

Deleting rows dataframe in R conditional to “if any of (a specific variable) is equal to”
Dear list,
I have been struggling for some time now with this code... I have this vector of unique ID "EID" of length 821 extracted from one of my dataframe (skate). It looks like this:

I would like to remove the complete rows in another dataframe
