Hello,
I need your help.
I was asked to do this :
Divide your dataset into two subsets: Subset A and Subset B. Subset B
includes the “individuals” whose missing values for the variable
“Esperance_maintien” (you can use “filter”, “!is.na” or “is.na”).
I tried this but i have an empty database ...
data <- read_csv("C:/Users/ABC/Downloads/sgl-arbres-urbains-wgs84.csv")
View((data$esperance_maintien))
summary(data$esperance_maintien)
SubsestB <- subset(data, esperance_maintien == "NA")
View(SubsestA)
THANKS
Anis
