Is there an R function that implements the finite element method?

Question

Is there an R function that can solve a partial differential equation using the finite element method (Strang and Fix, 1973)?

Based on the wikipedia list of finite element software packages, the method has been implemented in Fortran, C. Both Fortran and C can be called by an R function, but I do not see any such functions in CRAN.

Answer 1

There is a book which tackles this topic exclusively:

Finite Element Computations in Mechanics with R: A Problem-Centered Programming Approach 1st Edition Khameel Bayo Mustapha

Answer 2

There is a new package that uses Finite Element Method (FEM). I think that's one of the first steps for using FEM in R.

fdaPDE

Answer 3

I have found no evidence for such a function:

The following quote from an article in the R Journal article on ODE's and PDE's implies that such functionality was not present at the time of publication (2010):

Extending the PDE approach to finite elements (Strang and Fix, 1973) would open up the application domain of R to any irregular geometry.
