In the Access to Opportunities Project we have been working on a database with the distribution of population and activities data for the 187 Brazilian urban concentrations. Preview: population distribution on Rio de Janeiro's urban concentration with the 3 resolutions available.

No Projeto Acesso a Oportunidades nós temos trabalhado em uma base com a distribuição de dados socioeconômicos e de atividades pras 187 concentrações urbanas do Brasil. Uma prévia: distribuição da população na concentração urbana do Rio de Janeiro, nas 3 resoluções disponíveis.

📦 {accessibility} v1.2.0 is on CRAN! This new version includes two functions to calculate inequality measures, concentration_index() and theil_t(). This blog post covers their usage: https://t.co/uZUmGfJ7Bp

[Daniel Herszenhut @dhersz]

We have already been using these features in our workflow at the Access to Opportunities Project. I hope you find them useful as well 😁

[Daniel Herszenhut @dhersz]

📦 A new version of the {accessibility} R package has finally arrived on CRAN with several new goodies! 🥳 This blog post covers the main features of the new version: https://t.co/L5HFDpEsY6

[Daniel Herszenhut @dhersz]

{accessibility} v1.1.0 is filled with functions that help making accessibility research more methodologically robust. New accessibility measures, poverty and inequality measures, the ability to consider multiple cutoffs/decay values and multiple travel costs.

[Daniel Herszenhut @dhersz]

@ymaricarneiro is another co-author of the balancing cost measure! Sorry Mari, I swear I tried to find if you had an account here...

[Daniel Herszenhut @dhersz]

The {accessibility} R package has received some new functions 🥳: balancing_cost() and palma_ratio()

[Daniel Herszenhut @dhersz]

By the way, you can see both functions in action in the package website.

@IrlanSimoes oi irlan, beleza? o link pro livro físico na página da corner no linktree está errado. o novo link é esse: https://t.co/6eApFeLgUA

@soukhov_a @paezha @higgicd @Moataz_MMohamed Please @soukhov_a et al feel free to test it and propose any changes to documentation, parameters, etc etc. I have tested with the paper example got the same results (very minor differences, probably due to rounding, I guess).

[Daniel Herszenhut @dhersz]

On a sudden productive procrastination impulse, I have added the spatial availability accessibility measure, proposed by @soukhov_a, @paezha, @higgicd and @Moataz_MMohamed, to the {accessibility} R package. Check it out: https://t.co/Dl3uxZjvkj

36 segundos que valem ser gastos com esse corte. @flaviaol claríssima e didática. Não dá pra fingir que quem estava "se manifestando pacificamente" é inocente, porque a simples presença, reivindicando um golpe, é crime.

@flaviaol: "Ninguém que estava ali era inocente. [...] Foram ali reivindicar um golpe de Estado, a abolição do Estado Democrático de Direito. Por si só, isso é o crime ".

📦 {gtfstools} v1.2.0 is on CRAN!
🔗 https://t.co/Rkm0ywbxmv

The most recent version of the package includes a function to validate GTFS feeds! validate_gtfs() wraps @MobilityDataIO Canonical GTFS Validator in a very simple interface.

[Daniel Herszenhut @dhersz]

Using it is as simple as:

library(gtfstools)
data_path <- system.file("extdata/spo_gtfs.zip", package = "gtfstools")
validator <- download_validator(tempdir())
validate_gtfs(data_path, output_path = tempdir(), validator_path = validator)

The result:
