Calculate area under the disease progress curve (AUPDC)

Usage

Audpc(evaluation, dates, type = "absolute", na.rm = FALSE)

Arguments

evaluation: Table of data of the evaluations: Data frame with evaluations as columns; or a vector of evaluations
dates: Vector of dates corresponding to each evaluation
type: "relative" or "absolute", relative returns a proportion, whereas absolute returns the area.
na.rm: logical, remove observations with either an NA in the evaluation or the date. Does not allow NA values at the start or end observations.

Value

Vector with relative or absolute area under the disease progress curve

Details

This is a wrapper for agricolae which checks for NA values and will return omit NA values if specified. However it will still return NA if the first or last values contain NA This is intentional as audpc values are completely not comparable when these values are missing. See help audpc for more details.

Examples

# see examples in help(agricolae::audpc)
dates <- c(14,21,28,32,39,41,50) # days
# example 1: evaluation - vector
evaluation <- c(1,2,4,15,40,80,90)
Audpc(evaluation,dates)
#> evaluation 
#>       1147 

# add NA values
evaluation<-c(1,2,4,NA,40,80,90)
Audpc(evaluation,dates, na.rm = TRUE)
#> [1] 1158.5
if (FALSE) agricolae::audpc(evaluation,dates) # \dontrun{}
# if NA is at the start or end of vector it will return NA
dates<-c(14,21,28,32,39,41,NA) # days
Audpc(evaluation,dates)
#> [1] NA
