  cache = TRUE,
  pack = TRUE,
  quiet = FALSE
)

Arguments

item	Type of weather data to be acquired. Mainly specifies the interval between records (e.g. daily or hourly). See NOTE for details.
block_no	Block number of the location to be observed. It is assumed that block_no is input as a string consisting of a 4- or 5-digit number. If a numeric value is specified, it is processed as a string.
