getting values from arrays using which()
Dear R-Help,
I have an array 1260x1260, upper triangle consisting of numbers between 0 and 100, and lower triangle all NA. I can extract the index of those values say above 99 using the following code:
which(myArray>=99 , ind.arr=T)
which returns:

Problems using "lm" in combination with "predict"
Hello everybody,
I'm trying to predict a linear regression model but it does not work.
My Model: y = Worktime + Vacation + Illnes + Bankholidays
My modelmatrix is of dimension 28x4
Then I want to make use of the function predict because there confidence.intervals are include.
My idea was:
mod <- lm(y~Worktime+Vacation+Illnes+Bankholidays)
newdate=data.frame(x=c(324,123,0.9,0.1))

How to estimate the parameters of differential equations from data
Hello list
I have a theoretical differential equation model (two coupled differential
equations) describing the acidification of dairy cultures in milk:
dX/dt = f(H, param)*X
dH/dt = g(param)*dX/dt
pH = -log10(H)
I also have actual data of the same.
I would like to estimate the parameters of the theoretical model from real
data, but don't know how to go about it in R (I'm fairly new

how to randomize a vector
I have a vector whose length is nearly 70 thousand.
I need randomize it for 1000 times .
for randomizing , I mean ,the elements of the vector remain intact while
their order in the vector get changed randomly.
I have written a function which seems to be able to solve short vectors ,
but waste a lot of time when dealing with the the long vector mentioned
above.

R and excell differences in calculation F distributionfunction
R-help,
I'm trying to work out the density function by doing:
> df(5.22245, 3, 22)
[1] 0.005896862
> df(15.20675, 6, 4)
[1] 0.001223825
In excell the result is :
0.0071060464 <*> FDIST(5.22245,3,22)
0.0100001406 <--> FDIST(15.20675,6,4)
>From my point of view the differences in the second case
are substantial.
Can anyone give me a hint on this?
Thanks in

contourplot lines, text, and mtext
If I have a contourplot (in the lattice package) and I want to add
straight lines to it, how do I do this?
I see that there are llines() and lsegement() functions for lattice
plots, but they don't seem to do anything in this case:
library(lattice)
library(KernSmooth)
x=rnorm(10000)
y=x+rnorm(x,0,.5)
a=bkde2D(cbind(x,y),.7)
z=as.vector(a$fhat)
grid=expand.grid(x=a$x1,y=a$x2)
