Filter FORCIS data by a spatial bounding box

Source: R/filter_by_bbox.R
filter_by_bbox.Rd

Filters FORCIS data by a spatial bounding box.

Usage

filter_by_bbox(data, bbox)

Arguments

data

a tibble or a data.frame. One obtained by read_*_data() functions.

bbox

an object of class bbox (package sf) or a vector of four numeric values defining a square bounding box. Values must follow this order: minimum longitude (xmin), minimum latitude (ymin), maximum longitude (xmax), and maximum latitude (ymax). Important: if a vector of numeric values is provided, coordinates must be defined in the system WGS 84 (epsg=4326).

Value

A tibble containing a subset of data for the desired bounding box.

Examples

# Import example dataset ----
file_name <- system.file(file.path("extdata", "FORCIS_net_sample.csv"),
                         package = "forcis")

net_data <- read.csv(file_name)

# Dimensions of the data.frame ----
dim(net_data)
#> [1] 2451   86

# Filter by oceans ----
net_data_sub <- filter_by_bbox(net_data, bbox = c(45, -61, 82, -24))

# Dimensions of the data.frame ----
dim(net_data_sub)
#> [1] 320  86
