aacp function

Utils: Area under the curve

Performs the calculation of the area under the progress curve. Initially created for the plant disease area, whose name is "area under the disease progress curve", it can be adapted to various areas of agrarian science.

aacp(data)

Arguments

• data: Data.frame containing evaluations in columns. Column names must be numeric and not dates or characters

Returns

Returns a vector with the area values under the curve

Note

Just enter the data. Exclude treatment columns. See example.

Examples

#=======================================
# Using the simulate1 dataset
#=======================================
data("simulate1")

# Converting to readable format for function
dados=cbind(simulate1[simulate1$tempo==1,3],
            simulate1[simulate1$tempo==2,3],
            simulate1[simulate1$tempo==3,3],
            simulate1[simulate1$tempo==4,3],
            simulate1[simulate1$tempo==5,3],
            simulate1[simulate1$tempo==6,3])
colnames(dados)=c(1,2,3,4,5,6)
dados

# Creating the treatment vector
resp=aacp(dados)
trat=simulate1$trat[simulate1$tempo==1]

# Analyzing by DIC function
DIC(trat,resp)
