如何使用样本权重和分类数据进行可视化？

Question

If one has a data set that looks as follows:

data <- data.frame()
data$gender <- c(F,F,F,M,F)
data$province <- c(G,N,K,L,K)
data$volume <- c(500,750,1250,NA,300)
data$weight <- c(1.36,0.67,5.22,1.66,1.14)

How do I apply these weights to the data set? Is it enough to just multiply the sample weights with the numerical variables or do the categorical variables also have to be weighted?

Answer 1

The questionr and survey packages handle weighting. Here's an example:

library("questionr")
table <- wtd.table(data$gender, weights = data$weight)
barplot(as.matrix(table))
