为什么我的意外事件table中有多余的行和列?
Why are there redundant rows and columns in my contingency table?
我是R新手,目前正在学习应急table。我想使用来自“loans_full_schema
”(来自 openintro)的数据以及“application_type
”和“homeownership
”数据来创建应急 table。下面是我的代码。
library(oibiostat)
data("loans_full_schema")
tab <- table(loans_full_schema$application_type, loans_full_schema$homeownership)
tab
我的结果是my outcome
然而,我希望能够得到如下结果wanted outcome
所以我的问题是为什么我的结果中有一个“任何”列和一个空白行?
那是因为数据中有空位
levels(loans_full_schema$homeownership)
#[1] "" "ANY" "MORTGAGE" "OWN" "RENT"
levels(loans_full_schema$application_type)
#[1] "" "individual" "joint"
您可以使用 droplevels
删除它们。
loans_full_schema <- droplevels(loans_full_schema)
table(loans_full_schema$application_type, loans_full_schema$homeownership)
# MORTGAGE OWN RENT
# individual 3839 1170 3496
# joint 950 183 362
您可以使用 addmargins
来添加总数。
addmargins(table(loans_full_schema$application_type, loans_full_schema$homeownership))
# MORTGAGE OWN RENT Sum
# individual 3839 1170 3496 8505
# joint 950 183 362 1495
# Sum 4789 1353 3858 10000
