Create mathematical art with R

mathart's Issues

R version

Fantastic package! I recommend possibly relaxing this requirement:

ERROR: this R is version 3.4.3, package 'mathart' requires R >= 3.4.4
Installation failed: Command failed (1)

ggart?

The ggart thing is no longer on github and can't be pulled on R. I'm a bit of a noob so I don't know how to pull it off rdrr.io.

mathart export to SVG

Currently saves beautiful PNG files. I would love to be able to save those generated images as an SVG so I could plot them.

Nice work thanks for sharing!

theta_start argument error in mollusc() function

Hi Marcus--

If I enter -Inf for the theta_start argument of the mollusc() funtion, I receive the following error:

Error in seq.default(theta_start, theta_end, (theta_end - theta_start)/(n_t - :
'from' must be a finite number

For what it's worth: I copied parameters directly from the Cotie paper just to see what the function would do. Any clues about what I might be doing wrong?

Install fails

Installation with devtools fails with or without commit number. Showing below with a 9 month old commti, but I tried lots in between:
devtools::install_github(repo = "marcusvolz/mathart", commit = "2ca706c")

Error in read.dcf(path) :
Found continuation line starting ' person("Marcus", ...' at begin of record.

By contrast,
devtools::install_github(repo = "marcusvolz/ggart")
works fine. One difference is the DESCRIPTION file has only one authors@R line.

devtools::install_github("marcusvolz/mathart") fails

Hi Marcus,

I am trying to install your packages as per https://github.com/marcusvolz/mathart/blob/master/README.md.

However, when I run

devtools::install_github("marcusvolz/mathart")

I get below output (note the error "Error: Failed to install 'mathart' from GitHub" and everything below). For some reason, I don't have your folder

marcusvolz-mathart-e792c15

in C:\Users\chris\AppData\Local\Temp\Rtmp8YcPnw\remotes3d6819ce6dd2...

Any idea what's going on here/how I can fix this so that I can use your package? :) Thanks!

Chris

Less intensive mollusc-shell example?

Howdy,

I love the Raup-esque mollusc shell visualization (Dave Raup was one of the more prominent figures in modeling shell growth), but I'm curious if you could provide an example that was less system intensive? Even one shell, rather than all three as in your example, is pretty laborious for a laptop with a lot of memory, and I'd like to use it in a classroom environment. I'm not sure I understand at what resolution the visual is being generated, though, or if that's even the main bottleneck.

Really fantastic work, though, and I've enjoyed playing around with this package quite a bit!

Image resolution issues

Can you boost the resolution of the final images that get generated (e.g., the butterfly or mollusk images)? When I zoom in, the images appear pixelated.
