In amadeus: Accessing and Analyzing Large-Scale Environmental Data

Calculate temporal dummy covariates

Description

Calculate temporal dummy covariates at point locations. Returns a data.frame object with locs_id, year binary variable for each value in year, and month and day of week binary variables.

Usage

calculate_temporal_dummies(
  locs,
  locs_id = "site_id",
  year = seq(2018L, 2022L),
  geom = FALSE,
  ...
)

Arguments

locs	data.frame with a temporal field named "time"
locs_id	character(1). Unique site identifier column name. Default is "site_id".
year	integer. Year domain to dummify. Default is seq(2018L, 2022L).
geom	FALSE/"sf"/"terra".. Should the function return with geometry? Default is FALSE, options with geometry are "sf" or "terra". The coordinate reference system of the sf or SpatVector is that of from.
...	Placeholders.

Value

a data.frame or SpatVector object

Examples

## NOTE: Example is wrapped in `\dontrun{}` as function requires a large
##       amount of data which is not included in the package.
## Not run: 
loc <- data.frame(id = "001", lon = -78.90, lat = 35.97)
calculate_temporal_dummies(
  locs = loc,
  locs_id = "id",
  year = seq(2018L, 2022L)
)

## End(Not run)
