fireTypeLowToHigh: FireType Low to high

In nevilamos/FAMEFMR: Functions For DELWP FAME Fire Analysis

FireType Low to high

Description

Helper function to deal with cases where there is a LOW intensity fire ( planned Burn) shortly after a HIGH intensity Fire, shortly after is defined as <= max_interval

Usage

fireTypeLowToHigh(
  max_interval = NULL,
  Interval_Matrix = Interval,
  Firetype_Matrix = FT_matrix
)

Arguments

max_interval	the maximum inter fire interval where a LOW firetyppe for the second fire should be coverted to HIGH
Interval_Matrix	matrix of sequential intervals between fire in unique fire history sequence ( generated internally as party of FAMEFMR::fhProcess())
Firetype_Matrix	firetype matrix giving fireTypes (1=LOW 2=HIGH) for fires in unique fire history sequence ( generated internally as party of FAMEFMR::fhProcess())

Value

modified Firetype_Matrix where the fireytpe of LOW fires have been changed to HIGH if the interval since the last LOW fire is <=

Examples

#firetype matrix giving fitetypes (1=LOW 2=HIGH) for fires in unique fire hsitory sequence ( generated internally as party of FAMEFMR::fhProcess())
FT_matrix<-structure(c(2, 2, 2, 2, NA, 1, 2, 2, NA, NA, NA, 1), dim = 4:3, dimnames = list(NULL, c("FireType01", "FireType02", "FireType03")))

#Fire interval matrix
Interval<-structure(c(NA, 245L, 235L, 235L, NA, NA, NA, 10L), dim = c(4L, 2L), dimnames = list(NULL, c("INT01", "INT02")))
fireTypeLowToHigh(max_interval = 5,Interval_Matrix = Interval,Firetype_Matrix = FT_matrix)
