---

Method new()

Initialize options

Usage

PGOptionsManager$new()

---

Method reset_options()

Reset options to defaults.

Usage

PGOptionsManager$reset_options()

---

Method set_extent()

Set output spatial extent

Usage

PGOptionsManager$set_extent(value)

Arguments

value

A vector with extent, c(xmin, xmax, ymin, ymax)

---

Method set_crs()

Set output CRS

Usage

PGOptionsManager$set_crs(value)

Arguments

value

CRS string

---

Method set_nrow()

Set number of rows in output raster

Usage

PGOptionsManager$set_nrow(value)

Arguments

value

Integer

---

Method set_ncol()

Set number of cols in output raster

Usage

PGOptionsManager$set_ncol(value)

Arguments

value

Integer

---

Method set_rawfolder()

Set the folder where raw-data should be downloaded (possibly very large files), defaults to temporary folder

Usage

PGOptionsManager$set_rawfolder(value)

Arguments

value

String path to folder

---

Method set_verbose()

Set verbose output of functions if true.

Usage

PGOptionsManager$set_verbose(value)

Arguments

value

Boolean

---

Method set_temporal_resolution()

Set temporal resolution

Usage

PGOptionsManager$set_temporal_resolution(value)

Arguments

value

---

Method set_start_date()

Set start date

Usage

PGOptionsManager$set_start_date(value)

Arguments

value

The date used globally to build PRIO-GRID. The month and day are used to define the measurement date within the temporal resolution (e.g., as.Date(1900-06-30) would slice June 30 every year for compatible data sources).
