Expand Life-History Data Frame for Species and Regions
expand_life_history.Rd
This function takes a life-history data frame where multiple marine regions for each species are listed in a single cell, separated by commas. It expands this data frame so that each species-region combination gets its own row, with marine regions translated into their full names.
Value
A data frame where each species-region combination is represented in a separate row.
The marine_region
codes are expanded to their full names (e.g., "NW" to "North-west").
Examples
# Create a sample data frame with species and comma-separated marine regions
dat <- data.frame(
species = c("Species A", "Species B"),
marine_region = c("NW, N, CS", "TE, SE")
)
# Expand the data frame to have one row per species-region combination
expanded_dat <- expand_life_history(dat)
# Check the result
print(expanded_dat)
#> # A tibble: 5 × 2
#> species marine_region
#> <chr> <chr>
#> 1 Species A North-west
#> 2 Species A North
#> 3 Species A Coral Sea
#> 4 Species B Temperate East
#> 5 Species B South-east
