[R-pkgs] Announcing eulerr 1.0.0

Dear R users,

I would like to announce version 1.0.0 of eulerr (https://cran.r-project.org/package=eulerr). eulerr produces venn and euler diagrams for any number of sets. The user inputs a string of set relationships, for instance eulerr(c("A" = 10, "B" = 5, "A&B" = 2)), and out pops a specification for a euler diagram that can be plotted via eulerr.

For some set relationships, there is no perfect solution in the form of a euler diagram; in these cases, eulerr offers an approximation using numerical optimization and provides the user with diagnostics that reveal if the approximation can be trusted.

In this version, most of the optimization routines have been ported to C++ via Rcpp and RcppArmadillo, label placement has been improved, and additional loss functions for the optimization have been introduced. For a complete list of the updates, please see https://cran.r-project.org/package=eulerr/news.html

Finally, please visit the repository at https://github.com/jolars/eulerr if you are interested in contributing.

All the best,
