Dennis,
If I understand correctly, you should be able to do something like this
(example with exponential decay):
these.x - (1:10)/10
plot(these.x,exp(-these.x),type=l) # create a basic plot for starting
point
this.usr - par(usr)# get the plotting region limits
# they are xleft, xright,
Try this:
foo - function(x) {
data.frame(Id = unique(x$Id), rbind(range(x$time)), dose =
unique(x$dose))
}
t(sapply(split(as.data.frame(orig.data),
with(rle(orig.data[,'dose']), rep(seq_along(lengths),
lengths))),
foo))

I've recently stumbled across data.table, Matthew Dowle's package. I'm
impressed by the speed of the package in handling operations with large
data.frames, but am a bit overwhelmed with the syntax. I'd like to express
the SQL statement below using data.table operations rather than sqldf (which

I have a survey on LimeSurvey ( https://www.limeservice.com/ ) going and I
am preparing data analysis. Data exports to R dumps are completed and works.

Dears,
does anyone know, how I can get R to save the values of an array in a csv like
file using write(), but without printing NA to the file? I use ';' to seperate
the elements, so :
a=c(1,NA,2,3,3)
write(a)
should produce
1;;2;3;3
in the file.
Thanks in advance!
Hello, I would like to do Block LDL' factorization for Hermitian indefinite

triangular matrix (i.e a product of unit lower triangular and permutation
matrices) in L such that A = L*D*L'. The block diagonal matrix D has

stacked colors of the bar plot. I tried this, but it didn't work.

Hi,
I recently used columns of a matrix as inputs to nls(), which works just
fine, but then I get, for example,
(assuming nls(stuff)-nl30 was the original command)
nl30$call
nls(dr[,2]~apowr^(dr[,1])/(b*sqrt(dr[,1])))
Now, I can build a new matrix with same dimensions as dr and use that
to

You have to get the source and buld the package.
The change needed is in HtmlTree.R
You have to add return(str) at the end of the function definition.
The reason is that for loops now return NULL,
they returned (I think) the value of the last interation

Hi all,
I am writing here because the JRI mailing list seems abandoned...
maybe some of you guys know an answer or has a pointer into the right
direction.
I am quite confused by the jars that exist between rServe, JRI and
