extract_hazus_functions: Extract HAZUS damage functions for specified function type

Description

Extract HAZUS damage functions for specified function type

Usage

extract_hazus_functions(func_type = "depth", long_format = TRUE)

Arguments

func_type

Flood damage or depreciation function type. Choose one of depth (depth-damage functions), velocity (velocity-depth-damage functions), ag (damage functions for agriculture, based on duration of flooding), bridge (damage function for bridges based on the severity of the flood) or deprec (depreciation with age).

long_format

Logical flag to indicate whether raw data is desired or in a format suited for plotting using ggplot2. Damage function data from HAZUS are typically in the wide format.

Value

data frame, the number of rows and columns depend on the first argument of the function.

Examples

# depth-damage functions
fl_dept <- extract_hazus_functions()
# depth-damage functions, raw data only
fl_dept <- extract_hazus_functions(long_format = FALSE)
# velocity-depth-damage functions
fl_velo <- extract_hazus_functions(func_type = "velocity")
# agriculture damage functions
fl_agri <- extract_hazus_functions(func_type = "ag")
# bridge damage functions
fl_bridge <- extract_hazus_functions(func_type = "bridge")
# depreciation functions
fl_depr <- extract_hazus_functions(func_type = "deprec")
# columns names of all flood damage functions
lapply(ls(pattern = "fl_"), FUN = function(x) colnames(get(x)))
# flood occupancy types and description
data(haz_fl_occ)
head(haz_fl_occ)
