Re: [R] Plotting a triangular prism
Hi Erin, If you want a realistic 3D prism, I would use something like POVRay or other rendering software. You have to know your geometry, but you can get a very realistic image. I suspect that you want more than just a picture of a prism, so you can then generate a PNG image and use it as a layer in a composite image in something like the GIMP.

Re: [R] Plotting a triangular prism
One might think that after all these years you would have understood that “it’s not working” is an excessively imprecise description of, well, anything. Also html is deprecated severely on Rhelp. — David. Sent from my iPhone > On Nov 10, 2022, at 5:46 PM, Erin Hodgess wrote: > > Hello! > > I’m trying to draw a triangular prism.

[R] Plotting a triangular prism
Hello! I’m trying to draw a triangular prism. I have used rgl, plot3d, and it’s still not working as I would like. Has anyone done this, please? Thanks for any help.

[R-es] Leer txt con casos con diferentes columnas
Hola a todos Tengo ficheros de texto (.txt) en el que cada caso puede tener diferentes columnas (45 o 50). Si lo paso a mano a csv con excel no hay problema al leerlo en R, ya que lo lee y le asigna NA a las columnas que tienen 45 columnas. Pero no encuentro como hacer lo mismo en R cuando es txt, directamente ni lo lee “Error in scan(file = file, what = what, sep = sep, quote = quote, dec = dec, : line 626 did not have 45 elements” . Necesitaría que hiciera lo mismo que al leerlo en csv. ¿Me podríais ayudar?

[R] [R-pkgs] TDApplied version 2.0.0
Dear R users, I am very excited to announce TDApplied version 2.0.0 is now available on CRAN, with some significant improvements to the previous version. Topological data analysis is a powerful tool for finding non-linear global structure in whole datasets. 'TDApplied' aims to bridge topological data analysis with data, statistical and machine learning practitioners so that more analyses may benefit from the power of topological data analysis. The main tool of topological data analysis is persistent homology, which computes a shape descriptor of a dataset, called a persistence diagram. There are five goals of this package: (1) convert persistence diagrams computed using the two main R packages for topological data analysis into a data frame, (2) implement fast versions of both distance and kernel calculations for pairs of persistence diagrams, (3) provide methods for machine learning and inference for persistence diagrams which scale well, (4) deliver a fast implementation of persistent homology via a python interface, and (5) contribute tools for the interpretation of persistence diagrams. For details and examples please check out the github page https://github.com/shaelebrown/TDApplied or the README file on CRAN https://cran.r-project.org/web/packages/TDApplied/readme/README.html I sincerely hope that you will enjoy using this updated version and that it helps the field of topological data analysis progress in both academia and industry.
