...in the first line of the documentation for "symmpart". It currently reads, "symmpart(x) computes the symmetric part (x + t(x))/2 and the skew symmetric part (x - t(x))/2 of a square matrix x.". It should read, "symmpart(x) computes the symmetric part (x + t(x))/2 and skewpart the skew symmetric part (x - t(x))/2 of a square matrix x." Hope this helps.

...kinds of S/R indexing and some new generic functions such as lu() {LU decomposition} Schur(), BunchKaufman(), norm(), rcond() {Matrix norms and condition numbers} expm() {Matrix exponential}, band(), triu(), tril() {extract band-diagonal or triangular sub-matrices} symmpart(), skewpart() { (x + t(x))/2 and (x - t(x)) / 2 } are provided. Further, an extension to the xtabs function xtabs(*, sparse=TRUE) for large sparse, two-way contingency tables and coercion of one *factor* (possibly crossed with one <numeric>) to the corresponding (potentially huge) sparse model mat...
