help for segmented package
Hi,
I am trying to find m breakpoints of a linear regression model. I
used the segmented package. It works fine for small number of
predicators and breakpoints.(3 r.v. 3 points). However, my model has
14 variables it even would not work even for just one breakpoints!.
The error message is always estimated breakpoints are out of range.
Since my problem is time related problem. So I

String mathematical function to R-function
hello
I make a subroutine that give-me a (mathematical)
function in string format.
I would like transform this string into function ( R
function ).
thanks for any tips.

#e.g.
fun_String = "-100*x1 + 0*x2 + 100*x3"
fun <- function(x1,x2,x3){

Help interpreting output of Rprof
Hello there,
I am not quite sure how to interpret the output of Rprof (in the following the output I was staring at). I was poking around the web a little bit for documentation but without much success. I guess if I want to figure out what takes so long in my code the 2nd table $by.total and the total.pct column (pct = percent) is the most helpful. What does it mean that [ or [.data.frame is

How to transform the Matrix into the way I want it ???
Hi, R users,
I'm trying to transform a matrix A into B (see below). Anyone knows how to
do it in R? Thanks.
Matrix A (zone to zone travel time)
zone z1 z2 z3 z1 0 2.9 4.3 z2 2.9 0 2.5 z3 4.3 2.5 0
B:

4.3 z3 z2 2.5 z3 z3 0
The real matrix I have is much larger, with more than 2000 zones. But I

I _think_ there is a problem with the license as well: Z3 is MIT, so clang
would have to be released with Z3's license.

about lm restrictions...
Hello all R-users
_question 1_
I need to make a statistical model and respective ANOVA table
but I get distinct results for
the T-test (in summary(lm.object) function) and
the F-test (in anova(lm.object) )
shouldn't this two approach give me the same result, i.e
to indicate the same significants terms in both tests???????
obs.
The system has two restrictions:
1) sum( x_i ) = 1

[LLVMdev] Measurements of the new inlinehint attribute
Friday I enabled the inlinehint function attribute in the inliner. It mostly affects the performance of -Os compiled code. I have made some measurements on the SPEC test suite to show what it means.
I made three runs of then nightly tests. The baseline represents -Os with no inlinehint:

problem with "unique" function
I have the joint distribution of three discrete random variables z1, z2 and
z3 which is captured by "z"
and "prob" as described below.
For example, the probability for z1=0.46667, z2=-1 and z3=-1 is 2.752e-13.
Also, the probability adds up to 1.

problem with "unique" function
Most likely, previous computations have ended up giving slightly different values of say 0.13333. A pragmatic way out is to round to, say, 5 digits before applying unique. In this particular case, it seems like all numbers are multiples of 1/30, so another idea could be to multiply by 30, round, and divide by 30.

String Manipulation- Extract numerical and alphanumerical segment
I am currently attempting to split a long list of strings (let's call it
"string.list") that is of the format:
"1234567.z3.abcdef-gh.12"
I have gotten it to:
"1234567" "z3" "abcdef-gh" "12"
by use of the strsplit function.
This leaves me with each element of "string.list" having a split string of
the above format. What

Solving binary integer optimization problem

I am new to R for solving optimization problems, I have set of communication

I want to determine optimal number of communications for each channel

extraction
Hello everybody
I am trying to extract some observations from a data frame, ie the
subjects that belong to a given group, and although t-test etc work
if I try to obtain the number of subjects in the subgroup i get some
funny numbers. All the subjects with NA for group are included in
the subgroups 'group==1' etc.
Is this a bug?

Dear All,
I am a research student in environment. I have only little programming knowledge. I am currently doing the last project about rainfall impact on ground water quality in an area. It happens that I have to use R to read rainfall data (3 dimension) from ASC file (*.asc), and then write them into one NCDF file (*.nc).
I have been working very hard on study R, but I
