Hi,
Please, how can I determine parameters from exponential equation
Example one: y = a*exp(-b*x); how do I determine �a� and �b�, as well as
R-square from data sets. And also fitting y = a*exp(-b*x) into the data sets
Assuming data sets
A = (0,2,4,6,8,10)
B = (1,0.8,0.6,0.4,0.2,0.1)
Thanks
Fra
I consider R to be secure. It is possible, but very unlikely, that there
are some back door traps in R where somebody could access your data.
There is no software that is 100% secure and R is not 100% secure.

Hello,
There are now three solutions to the OP's problem.
I have timed them and the results depend on the matrix size.
The solution I thought would be better, Enrico's diag(), is in fact the
slowest. As for the other two, Eric's for loop is 50% fastest than the
matrix index for small matrices
Wow, thank you Jeff, that’s got it!

Hello all,
I want to download R and use it for work purposes. I hope to use it to analyse
very sensitive data from our clients.

Joanna,
You normally need to export _all_ the objects/functions that you expect users
to be able to run.
And if you are giving an example of a function, it seems likely that you expect
users to use it, so it

You only need one "for loop"
for(i in 2:nrow(myMatrix)) {
myMatrix[i-1,i-1] = -1
myMatrix[i-1,i] = 1
}

Thanks!
If I do it like this:
myMatrix <- matrix(0,5,5*2-3)
print(myMatrix)
for(i in 2:nrow(myMatrix))
for(j in 2:ncol(myMatrix))
myMatrix[i-1,j-1] = -1
myMatrix[i-1,j] = 1
print(myMatrix)
I get the following result:
[,1] [,2] [,3] [,4] [,5] [,6] [,7]
[1,] -1 -1 -1 -1 -1
Dear community,
I am trying to submit my first R package to CRAN and stumbled upon the

Most of my methods, are not exported to the namespace using the @examples

Will I have to provide @examples for these methods in the documentation? If
yes, I have the problem that w
