solving for a 2D transformation matrix
...points. I want to use this subset of points to compute
a best-fit transformation matrix so that the remaining points can be
converted to world coordinates.
The transformation matrix is (I think) of the form:
[ x' ] [ a11 a12 a13 ] [ x ]
| y' | = | a21 a22 a23 | | y |
[ w' ] [ a31 a32 a33 ] [ w ]
where:
x,y = page coordinates
x',y' = world coordinates
a13 = translation of x
a23 = translation of y
a11 = scale * cos(theta)
a12 = sin(theta)
a21 = -sin(theta)
a22 = scale * cos(theta)
a31 = 0
a31 = 0
a33 = 1
w' =...

Permutation of a distance matrix
...s and columns of a symmetrical matrix that represents ecological or actual distances between objects in space. The permutation is of the type used in a Mantel test.
Specifically, the permutation has to accomplish something like this:
Original matrix addresses:
a11 a12 a13
a21 a22 a23
a31 a32 a33
Example permutation
a22 a23 a21
a32 a33 a31
a12 a13 a11
that is relative positions of rows and columns are conserved in the permutation.
Basically, I have been doing this in a "for" loop by (1) permuting the raw data vector using "sample", (2) gene...

How to get all possible combinations?
Dear all, suppose I have a vector with elements as:
Vec <- c(2,3,4,5,6)
Now I want to have all possible combination of length 3 using those
elements and without any repetition. Like, I want to have 1
possibility like 2-3-4 but not 3-2-4.
Can somebody guide me how to achieve that in R?
Thanks for your help.

Matrix stability problem
Hello,
This is not a problem with R, the calculated results are mathematically
correct. This a matrix stability problem. Because of measuring errors, my
matrix solution is a bit off.
Here is what my equations look like:
A11 x11+A12 x12 +A13 x13 = b1
A21 x21+A22 x21 +A23 x23 = b2
A31 x31+A32 x31 +A33 x33 = b3
A is a reading, X is a measured weight, and b is total. The 3 experiments
give slightly different X values because of measurement errors.
For reproducibility, here's my A, x and b matrices and vectors
A <-matrix(
c(0.03,0.02,0.04,0.01,0.015,0.03,-0.01,-0.02,0.03),3...
