Installation

rKolada is on CRAN. To install it, run the following code in R:

install.packages("rKolada")

To install the latest development version from GitHub, use the remotes package:

library("remotes")
# remotes::install_github("LCHansson/rKolada")
install.packages("rKolada", repos = c('https://lchansson.r-universe.dev', 'https://cloud.r-project.org'))

Enhanced caching with nordstatExtras

For multi-user web applications or workflows that benefit from a shared, persistent cache, rKolada integrates with the nordstatExtras package. When installed, get_values(), get_kpi(), and other functions can write to a shared SQLite file instead of per-session .rds files:

# install.packages("devtools")
devtools::install_github("LCHansson/nordstatExtras")

library(nordstatExtras)
handle <- nxt_open("cache.sqlite")

# Data and metadata are cached in the same SQLite file
kpis <- get_kpi(cache = TRUE, cache_location = handle)
vals <- get_values(
  kpi = "N03700", municipality = c("0180", "1480"),
  cache = TRUE, cache_location = handle
)

nxt_close(handle)

Features include cell-level deduplication across overlapping queries, cross-query freshness propagation, and FTS5-powered typeahead search via nxt_search(). See the nordstatExtras README for details.
