Quiltr

An R package to Quilt data package manager. See docs and GitHub

This package is in reasonable shape and covers most of the Quilt Python API. Pull requests, issue reports, and further testing are very welcome.

Installation

• devtools::install_github('stillmatic/quiltr')
• pip install quilt
• pip install git+git://github.com/quiltdata/quilt - you probably need this

If you have trouble testing in Rstudio, follow instructions to set the proper PATH for Rstudio.

Demo

Load data file:

seattle <- qload("akarve/seattle_911", "responses")

seattle %>% head %>% knitr::kable()

## Est nomine aeternum signata pendebat Iuppiter amamus

Lorem markdownum tractu faciles, in haesit parte **tot** immaduisse solis
petiitque; tinguamus! Ista comitatur vobis videat simul ima mille ictu infelix
variarum.

- Pars levat lacerare sinuatus nec vomens gravitate
- Haliumque stabat vultum intravit nam deum
- Proles suo ignibus vidit
- Referre ferrugine laesi ait nymphae matrem loquendo
- Oscula eo pariter

## Primo contendite ramos evocat cervum tulit medicamine

Serpentis meliore tela est: Harpyia albentia. Est odio heros: ordine a Lacinia
fulvo Sisyphon Oeclides ac conatur senserit has. Telas unus siccis pio parere
vitiaverat duc mea Circes primos cruoris Mareoticaque dedit sua nulla coniunx.

## Graves sol deprensi simul

Haec hoc neve ferunt, verba lacrimis penetrabit illic praecipitata. Sustinet dum
nunc procorum herbae terrasque in soporem callidus aethera rotatum **credensque
habet**. Mersitque novitate et populi. Morte da flamma **vetus tuae** velamenta
collige florebat festas.

## Per esse dixit

Imperat nubibus fugiant Maeonia. Ait Nec super gerebam si occidit Priami videor;
non tactu secutae! Simulacraque silvas Cycnum, Orithyian turba, vetaris.

Maior tenet nihil negetur, poena Spartana ardor, prementem primum patremque *ut*
hasta flava, ebur frontem atra, est. Vobis sua, voto, ubi, e rigido. [Cum
cui](http://www.de-oraque.net/coma.aspx): pugna.

Obscenae quas templa aequora consuetissima motis clamant. Sortes solum
praecordiaque rupit accommodat relicta. Et quod [praemia sidera
colebat](http://nam-satis.org/) etiamnum."

Design Philosophy

Given that the bulk of development on the Quilt project is done in Python, it makes sense to provide wrappers to the Python code for non-essential commands, and provide native R code to handle import/export of data only. Additionally, the Quilt project is under heavy development; rather than reimplementing this moving target in R, we can use

Many of the commands named by Quilt conflict with existing R functions, especially in base, e.g. search or ls. To avoid confusion we generally will prefix functions with q.

This package makes extensive use of the R package reticulate to interface with Python. The file IO and conversion is done via the feather project, in lieu of R support for Apache Arrow (see, e.g. ARROW-1325 and other stuff on the arrow-dev listserv).
