Log Logistic Formula
Description
Log Logistic Formula
Usage
Log_Logistic_Formula(concentration, scale, shape_location)
Arguments
concentration |
The vector of concentration values for a selected pesticide, that has a Log Logistic shaped species sensitivity distribution, to run the equation on. |
scale |
The Log Logistic alpha/scale value for the selected pesticide. These can be found in the "pesticide_info" data frame provided in this package. If you are including other pesticides you will need to append them with their respective distribution variables to the "pesticide_info" table. |
shape_location |
The Log Logistic beta/shape value for the selected pesticide. These can be found in the "pesticide_info" data frame provided in this package. If you are including other pesticides you will need to append them with their respective distribution variables to the "pesticide_info" table. |
Value
a numeric vector
Examples
Imazapic <- c(0.000000001, 0.5, 2.7, 11)
#Imazapic is used as its species sensitivity distribution plots fits Log Logistic
Log_Logistic_Formula(concentration = Imazapic,
scale = pesticide_info$scale[pesticide_info$pesticide == "Imazapic"],
shape_location = pesticide_info$shape_location[pesticide_info$pesticide == "Imazapic"])
