[R] double subscripts with Greek letter

Hi all, I have a question which seems trivial but simply cannot figure out its solution. I want to type A_{\alpha,\beta} in the title of a plot. Uwe once pointed out a solution expression(A[alpha*beta]) But the output of the above command does not include the "," in the subscript. Is there a wa

Re: [R] Fitting Hastie's principal surfaces in R

I couldn't find anything, but you might try searching on "thin plate splines" on rseek.org. I realize these are different than principal surfaces, but they might nevertheless be useful to you. Or not. Cheers, Bert Bert Gunter "The trouble with having an open mind is that people keep coming al

Re: [R] how to extract weighted data in "survey" package

Thank You Anthony for the message. Why did not I get the same values in the following examples? To get the adjusted value, should not we just multiphy by weight? For example, I multiplied "api00" by "column "pw" (mean(apistrat$api00*apistrat$pw/100)) but I did not get the same value as of surve

[R] Fitting Hastie's principal surfaces in R

Hello, I need to summarize a three-dimensional dataset through a principal surface that passes through the middle of the data. Principal surfaces are non-linear generalization of the plane created by the first two principal components and provide a non-linear summary of p-dimensional dataset. P
