[R] Is there any Gauss-newton library/function in R?

[spencerg]

      There are many more things available than just 'nls'.  An overview 
is available at "www.r-project.org" -> CRAN (select your favorite 
mirror) -> "Task Views" (on the left, third line under CRAN) -> 
"Optimization      Optimization and Mathematical Programming". 


      For a possibly more direct route, you can try the following: 


library(RSiteSearch)
GN <- RSiteSearch.function("Gauss-Newton")
HTML(GN)


      This identified for me 19 different help pages in 11 different 
packages containing the term "Gauss-Newton". 


GN. <- RSiteSearch.function("Gauss Newton")
GN2 <- GN|GN.
HTML(GN2)


      This identified 27 help pages in 15 different packages containing 
both "Gauss" and "Newton". 


NR <- RSiteSearch.function("Newton Raphson")
NR. <- GN2|NR
HTML(NR.)


      This identified 138 help pages in 61 different packages, sorting 
them first by the package with the most matches. 


      Hope this helps.
