cumulus

The goal of cumulus is to simplify common CHD workflows,by providing utility functions for accessing our cloud infrastructure and other common data resources

Installation

You can install the development version of cumulus from GitHub with:

# install.packages("devtools")
devtools::install_github("OCHA-DAP/cumulus")

Examples

This is a basic example which shows you how to solve a common problem:

library(cumulus)
## basic example code

Blob

containers <- blob_containers()
AzureStor::list_blobs(
   container = containers$projects,
   dir = "ds-contingency-pak-floods"
 )

With convenience access to containers above could easily use {AzureStor} for flexible reading/downloading of files, but we've provided some convenient wrappers for reading some basic file types

df <- blob_read(name = "ds-aa-eth-drought/exploration/eth_admpop_2023.xlsx", container = "projects",stage= "dev")

blob_write() is now available and works almost exactly as blob_read(). Will add an example soon.

Postgres

connect to prod postgres db

con_prod <- pg_con(stage = "prod")

con_dev <- pg_con(stage = "dev")

Random utility

• fieldmaps

gdf_adm1 <- download_fieldmaps_sf("som","som_adm1")

• ENSO/ONI

df_oni <- load_oni()
