Others may have better suggestions.
A bit more work on the chunk evaluation approach within Emacs is one;
it almost does what is needed, but not quite.

This is more a statistic thing than an R question.

The problem is that I have different number of replicates for each combination of

What are the strengths and weakness of these
If A%*%thetac, then log(c-A%*%theta) returns NA. if A%*%thetac, log(A%*%theta-c) returns NA. Only when A%*%theta==c do you get a number from log(A%*%theta-c), and that's (-Inf).
However, for an equality constraint, I've had good luck by with an objective function that adds something

Is anyone aware of an R implementation of a matrix polar decomposition?

I can get it from SVD but I understand that this is inefficient when

Hi all;
Im working with two datasets in R, say data1 and data2. Both datasets
are composed of several rows and columns (dataframe) and some of the
rows are identical in both datasets. Im wondering if there is any way to
remove from one set, say data1, the rows that are identical in the other
set,
You have not given enough info. Do the data sets have the same columns? If
not, you need to tell us more about how you can tell whether one row of a
data frame is `identical' to some row of another.
Assuming the columns are the same between the two, the basic idea is to
combine all columns into
In short, merge with all=FALSE followed by removal of redundant columns might do the
trick.
If rownames serve as common key, use the argument by=0.
