Hans,
thanks for the suggestion and sorry for coming so late to the thread. I
have only a little to add to Ravi's comments.
I like the idea overall. Nothing prevents you from doing this, but you
should be committed to getting it up and running and then keeping it
updated.
Yes completely d'accord with all comments.
If you want to put together a .ctv, please have a look at
vignette("ctv-howto", package = "ctv")
and send me the resulting .ctv.
In addition to concurring with Berend's comments, I also would like to
mention that numerical analysis (NA) is an extremely broad category. I
am not sure how to restrict that in order to make the taskview
manageable.
I also completely agree with this. I'm not sure what the best way to focus
the task view is. Maybe differential equations should be in a separate
(relatively small) view? The experience is that very large task views
become harder to maintain in the future because the number of packages
will grow over time.
In any case, I look forward to seeing a new task view.
Thanks & best regards,
Z
How about including (i) convergence acceleration of sequences, (ii)
fourier transforms/wavelets, (iii) function approximation and special
functions of mathematical physics?
Best regards,
Ravi
P.S. I have a package called "eiginv" for solving certain types of inverse
eigenvalue problems (e.g., generating a matrix of a specific structure with a given set
of eigenvalues)

I am wondering if it would be time to have a new Task View, this time
for the subject of "Numerical Analysis and Differential Equations".
The list of packages possibly appearing in such a task view is already
quite long and could, for example, include:
Numerical Analysis and Linear Algebra
Bessel Bessel Functions Computations and Approximations
cubature Adaptive multivariate integration over hypercubes
elliptic Elliptic and related functions
expm Matrix exponential, logarithm, etc.
fdim Functions for calculating fractal dimension
gaussquad Collection of functions for Gaussian quadrature
gmp Multiple precision arithmetic
gsl Wrapper for the Gnu Scientific Library
hypergeo The hypergeometric function
irlba Fast partial SVD by Lanczos bidiagonalization
matlab MATLAB emulation package
multipol Multivariate polynomials
numDeriv Accurate numerical derivatives
onion Octonions and quaternions
orthogonalsplinebasis Orthogonal Bspline basis functions orthopolynom
Functions for orthogonal and orthonormal polynomials
polspline Polynomial spline routines
polynom Implement a class for univariate polynomial manipulations
PolynomF Polynomials in R
pracma Practical numerical math functions
pspline Penalized smoothing splines
quaternions Arithmetics and linear algebra with quaternions
R2Cuba Multidimensional numerical integration
RcppArmadillo Rcpp integration for Armadillo templated linear algebra library
RcppEigen Rcpp integration for the Eigen templated linear algebra
library
RcppOctave Rcpp integration of Octave
R.matlab Read and write of MAT files and R-to-Matlab connectivity
Rmpfr Multiple precision floating-point reliable
sparseGrid Sparse grid integration in R
spuRs Functions and datasets scientific programming and simulation
sspline Smoothing splines on the sphere
stinepack Stineman: consistently well behaved method of interpolation
svd Interfaces to various state-of-art SVD and eigensolvers
voronoi Methods and applications related to Voronoi tessellations
wavelets...
Simulation and Differential Equations
bvpSolve Solvers for boundary value problems of ODEs
ddesolve Solver for Delay Differential Equations
deSolve General solvers for initial value problems of ordinary
differential equations (ODE), partial differential equations
(PDE), differential algebraic equations (DAE), and delay
differential equations (DDE)
deTestSet Testset for differential equations
odesolve Solvers for Ordinary Differential Equations
PBSddesolve Solver for Delay Differential Equations
rootSolve Root finding, equilibrium and steady-state analysis of ODEs
sde Simulation and Inference for Stochastic Differential Equations
Sim.DiffProc Simulation of diffusion processes
simecol Simulation of ecological and other dynamic systems
and probably many more in the end. I left out the optimization
packages deliberately, but of course there would be a strong hint to
that task view.
If you put pracma in "Numerical Analysis and Linear Algebra", then I feel you
should also include BB and nleqslv under that heading. Both of these do things that can
be classified as Numerical Analysis. And both can of course also be used for simulation.
BB solve (sparse) systems of non linear equations using spectral gradient
methods nleqslv solve systems of nonlinear equations combining global
strategies with a Broyden or Newron method.
