Rcpp error

[ashley-isaac]

Hi there, thanks for a great package. I successfully created treemaps a month ago with the package, however, I suddenly received an error when running voronoiTreemap().

<simpleError in SysbioTreemaps::cropped_voronoi(sites): function 'enterRNGScope' not provided by package 'Rcpp'>

I tried running install.packages("Rcpp")' and this did not solve the problem. I am running on Ubuntu. Would you be able to help.

Thanks and looking forward to hearing from you. Best, Ashley

Hi Ashley, thanks for your interest in the package! The error you see is due to the fact that the package changed recently, dropping the original lib-cgal dependency and now depending only on R packages (that is BH, boost headers, and the external cgal4h, see README). I also encountered the error you see, it's about a random number generator. I think what solves the issue is to

• update all packages, particularly Rcpp
• (re)install the cgal4h package from gitlab
• (re)install SysbioTreemaps from github

PS: if you're using Rstudio, you can easily update all packages by going to main menu, Tools --> Check for package updates. Let me know if it does the trick.

Hi Michael,

Thank you so much for your speedy reply - I was just about to close the issue. I ran:

install.packages("remotes") remotes::install_github("m-jahn/SysbioTreemaps")

and I guess it updated everything in one go and that solved the issue. Thanks so much!
