[Rd] Cholesky/Choleski

[Enrico Schumann]

Dear all,

R docs differ in how the name Cholesky/Choleski is written.
Wikipedia at least has "Cholesky" (
https://en.wikipedia.org/wiki/Andr%C3%A9-Louis_Cholesky );
and this is also the only form that I have seen in the
literature (e.g. Golub/Van Loan)

The form "Choleski" comes up in chol.Rd, solve.Rd and
chol2inv.Rd (plus in a number of comments in C-code):

  src/library/stats/src/splines.c
  38: *   Choleski is more efficient.
  60: *   equations to determine them.  Either Choleski or Gaussian
  279:    /* Choleski decomposition */
  
  src/library/base/man/chol.Rd
  9:\title{The Choleski Decomposition}
  11:  Compute the Choleski factorization of a real symmetric
  28:  The upper triangular factor of the Choleski decomposition, i.e., the
  45:  If \code{pivot = TRUE}, then the Choleski decomposition of a positive

  26:  The inverse of the matrix whose Choleski decomposition was given.

  42: * CC--- choldc(nr,n,a,diagmx,tol,addmax)     is ``choleski + tolerance''


thank you & kind regards
