# Most important criteria using a multicriteria method in R

Is there someone here who has experience working with the multicriteria method in R?

Sorry if the question is incoherent, but I would like to know how I can find out which of the criteria used is the most important using some multi-criteria method in R. Can you help me?

``````#database
df1<- matrix(c(9000,2000,8000,1200,800,1000,7000,1200,9000),
nrow=3,
ncol=3,
byrow=TRUE)
colnames(df1) <- c("Consumption","Waste total","logistic costs")
row.names(df1) <- c("Propertie1","Propertie2","Propertie3")

Consumption Waste total logistic costs
Propertie1        9000        2000           8000
Propertie2        1200         800           1000
Propertie3        7000        1200           9000``````

If important is considered to be the proportion of costs for some combination of property and expense types
