Hi all,
I just compiled package dna v. 0.2 from source and am having some
difficulty with the window argument of the dotmatrix function.
Some test code; say I'm simulating some nucleotide sequences:
sequence1<-trunc(runif(200,0,4))
sequence2<-trunc(runif(200,0,4))
I embed a nice 100 ele
Hi all,
Does anyone know what happened to the dna library or the dotmatrix
function? For the life of me, I can't find it anywhere with the
exception of this reference:

Thanks!
Jeff.

I'm not sure I understand the question, but you might look into the
following functions:
unique
heatmap

Again, if I understand the question, you would create a length(unique
(x)) by length(unique(y)) sized matrix, and fill it with appropriate
values of z. Then pass that to heatmap or

"WTFM" again in responding.
The two issues that I originally had in understanding why the
operations behaved as they did were in (1) c() reducing an rbind the
way it did, and (2) vector recycling, as Peter mentioned. Issue (1
A couple days ago, Mark Leeds asked about a solution that would
basically stagger two lists, a and b, to return a list in the form of
a[1], b[1], a[2], b[2], a[3] In particular, the summary of his
question was in reference to lists defined by

How about using the cat function to concatenate the constant string
with the dynamic string and then bold the result of that?

Second part: you want to look at the residuals after specifying a
model? Just use the dependent variables in your subsample as the
dependent variables in your regression equation and subtract that
from your outcome variable in your subsample. Might not be the
answer to the question you
Much more elegant!
Is there a way, from the documentation, we would know that c() and
lists in general behave as they do in these two lines?

Note, the wrapped sort is a really tight solution but won't
necessarily always give you an "intertwined" array. For example, if
x=31 (or basically, tempin[2] or greater), then you would get 1, 31,
32, etc. instead of 1, 32, 31 Depends on what you were looking for.

Usage: everyOther(seq(1,1411, by=30), 5)
Sorry,

Funciton form:
everyOther <- function(tempin, x){
tempout[seq(1,length(tempin)*2, by=2)]<-tempin
tempout[seq(2,length(tempin)*2, by=2)]<-tempin+x
tempout

Is this what you're looking for?

If you were trying to use the sep="\t" argument, you might have

I would personally use the following method (example using the iris
data included with R):
data(iris)
tSelect <- (iris$Sepal.Length > 6.0 & iris$Sepal.Length < 6.2 & iris
$Sepal.Width == 3.0)
tSelectedData <- iris[tSelect,]
Then you can simply work with tSelectedData for whatever equation
