Is it possible to reverse engineer a data frame so that it's reproducible?
Like let's say I have a giant CSV from an employer or webpage that I want to make entirely reproducible. Is there a package or method to turn that into tibble(name = "...", id = "...", ...)
?
You should take a look at the datapasta
package. It has some size limitations (or rather, a lack of testing past certain sizes) but should do what you are looking for in terms of changing a df into a tibble input

Woah. That's incredible. Thanks for sharing!
For some reason, I'd never heard of dput()
in base R, but this is basically what I was looking for

For complex types dput()
may be your only option. But if your types are simple one of the other alternatives will be much more legible. Examples:
d <- data.frame(x = 1)
dput(d)
# structure(list(x = 1), class = "data.frame", row.names = c(NA,
# -1L))
cat(wrapr::draw_frame(d))
# d <- wrapr::build_frame(
# "x" |
# 1 )

Love it. I'll give it a try. So is the main problem with dput()
the messy output?
Yes, dput()
works great- but what it gives doesn't look like anything a user would type.
