Download a database extract from chronosphere remote server

The function will download a list of available series from the data repository

Usage

datasets(
  src = NULL,
  datadir = NULL,
  verbose = FALSE,
  master = FALSE,
  greetings = TRUE,
  all = FALSE
)

Arguments

src: character. Source identifier. If this is set to NULL, then a simplified list of availables series will be downloaded, including all unique src and ser combinations. If src is a valid source identifier, then all accessible products (resolutions and versions) of a series are shown.
datadir: character Directory where the downloaded files are kept. Individual entries will be looked up from the directory if this is given, and will be downloaded if they are not found. The default NULL option will download data to a temporary directory that exists only until the R session ends.
verbose: logical Should console feedback during download be displayed?
master: logical When src is NULL, should the function download the master records file?
greetings: logical When the function is invoked without arguments, it displays a message to keep new users informed about different versions and resolutions (even with verbose=FALSE). This argument turns this message off on demand.
all: logical When set to FALSE (default), only those items are shown that are available for the R environment. Set to TRUE to see all items.

Value

A data.frame class object.

Details

The function will download a single .csv file and attach it as a data.frame.

Examples

# available datasets (sources and series) - proper
# index <- datasets()
# all available versions and resolutions in database 'pbdb'
# oneDat <- datasets(src="pbdb")

ind <- datasets(
  datadir=system.file("extdata", package="chronosphere"))
#> Use datasets(src = <src>) to see available versions and resolutions.
# one available archive
ind <- datasets(
  src="SOM-zaffos-fragmentation",
  datadir=system.file("extdata", package="chronosphere"))
