ForamGrowthfT | R Documentation |
Implements the function for foraminifer growth rate as a function of temperature from Lombard et al. (2009) with parametrization from FAME 1.0 (Roche et al, 2018).
ForamGrowthfT( foram = c("sacculifer", "bulloides", "pachy_d", "siphonifera", "universa", "pachy_s", "dutertrei", "ruber"), temperature_K, norm = FALSE, min.growth.thresh = 0 )
foram |
Name of foram. |
temperature_K |
Temperature in Kelvin |
norm |
Optional normalizing factor |
min.growth.thresh |
Sets a lower cutoff for growth as a proportion of the maximum growth rate for that taxon. For example in Roche et al (2018) a cutoff of 0.1 was used, meaning all growth rates less than 0.1*max were set to zero. |
A numerical vector or matrix with the same dimensions as the object passed to temperature_K. Units are daily growth rate, unless norm == TRUE.
