Trobada analistes de dades

La idea és desvirtualitzar-nos, conèixer-nos, compartir informació... i després qui vulgui ens podem allargar i anar a prendre quelcom.
Accés obert a partir de les 15h15. Entrant per la porta del carrer (Provença 260), just la primera sala a l’esquerra.


1. Cas d'ús

Enviar correus des de la xarxa informàtica de la Generalitat de Catalunya (servidors amb outlook i office365), via scripting quan es compleixen unes condicions del negoci basades en dades.

Image

1.1. Exemple: posada a punt

Codi a Gitlab GenCat:
https://git.intranet.gencat.cat/ceb/informes-en-r

Cal escollir un sistema d'enviarment de correus, entre les opcions:

  • create_smtp_creds_key()
  • create_smtp_creds_file()
    amb els paràmetres: 
    create_smtp_creds_*(  id,
  user = NULL,
  provider = NULL,
  host = NULL,
  port = NULL,
  use_ssl = NULL,
  overwrite = FALSE
)

1.2. Crea clau smtp en configuració de sistema via nom proveïdor

# Creo la clau d'enviament de correus (i en windows) una vegada només
create_smtp_creds_key(
  id="foo_ceb",
  user = "foo@gencat.cat",
  provider = "office365",
  overwrite = FALSE
)
# The system key store has been updated with the "blastula-v1-foo_ceb" key with the `id` value "foo_ceb".
# * Use the `view_credential_keys()` function to see all available keys
# * You can use this key within `smtp_send()` with `credentials = creds_key("foo_ceb")`

1.3. Preparar objectes: gràfics ggplot2

p <- ggplot(mtcars, aes(x=wt, y=mpg, color=cyl, size=cyl)) +
      geom_point() +
      theme(legend.position="none")

p1 <- ggExtra::ggMarginal(p, type="histogram")

my_ggplot <- blastula::add_ggplot( p1 , width=5)

1.4. Preparar objectes: imatges

my_image <- blastula::add_image(file = system.file("img", "Rlogo.png", package="png"), width = 200)

1.5. Preparar objectes: taules

my_table_gt <- starwars %>% head() %>% gt() %>%   
  data_color(
    columns = birth_year,
    colors = scales::col_numeric(palette = "Blues", domain = range(0,800))
  ) %>% as_raw_html()


1.6. Composar el missatge - opció 1: compose_email()

Opció 1: compose_email(body=..., footer=...) 

correu_alerta1 <- blastula::compose_email(
    body = md(glue::glue(
"Benvolgut/da, acció requerida!:

Gràfic:
{my_ggplot}
Imatge:
{my_image}
Taula heatmap:
{my_table_gt}
")),
    footer = md(glue::glue("Correu enviat el {Sys.time()}."))
  )

1.7. Composar el missatge - opció 2: render_email()

Opció 2: render_email(input=".Rmd") 

correu_alerta2 <- blastula::render_email(input = "Plantilla 2.Rmd")

1.8. Afegir adjunts (pdf, htmlwidgets, ...)

correu_alerta1 <- correu_alerta1 %>%
  add_attachment(file = system.file('img', 'pexels-photo-267151.jpeg',package='blastula') ) %>% # Imatge via adjunt
  add_attachment(file = system.file('examples', 'austin_home_sales.csv',package='blastula') ) %>% # CSV
  add_attachment(file = system.file('doc', 'DT.html',package='DT') ) %>%# html autocontingut
  add_attachment(file = system.file('legacy', 'examples', 'choropleth', 'Rplots.pdf',package='leaflet') ) # pdf

1.9. Enviar el correu

# L'adreça "from" ha de ser real i existir al correu de gencat.cat, i ha de coincidir amb l'usuari que ha creat el seu "creds_key()" amb les seves credencials 
correu_alerta1 |>
  blastula::smtp_send(
    to = "direccio@lameva.aapp.cat",
    cc = "jo@lameva.aapp.cat",
    from = "automatitzacions@lameva.aapp.cat",
    subject = "Reviseu Canvis - Informe setmanal",
    credentials = creds_key("foo_ceb")
    )
