问题描述
我是 R 的新手.我有以下由字符组成的数据集(数据框):
I'm pretty new at R. I have the following data set (data frame) composed by characters:
"Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y"
"Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "N" "N" "Y" "Y" "Y"
"Y" "Y" "Y" "Y" "Y" "N" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y"
"Y" "N" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "N" "Y" "Y" "Y" "Y" "Y" "Y"
"Y" "Y" "Y" "Y" "Y" "Y" "N" "Y" "Y" "Y" "N" "Y" "Y" "Y" "Y" "Y" "Y"
"Y" "Y" "Y" "N" "Y" "Y" "Y" "Y" "N" "Y" "Y" "Y" "Y" "N" "Y" "Y" "Y"
"Y" "Y" "Y" "Y" "Y" "Y" "N" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y"
"Y" "Y" "Y" "Y" "Y" "Y" "N" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y"
"Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y"
"Y" "Y" "N" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y"
"Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y"
"Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y" "Y"
"Y" "Y" "Y" "Y" "Y" "Y" "N" "Y" "Y" "Y" "Y" "Y" "Y" "N" "Y" "Y"
我想用 1 替换 Y，用 0 替换 N.因此我使用以下表达式:
and I want to replace Y with 1 and N with 0. Thus I'm using the following expression:
ifelse(Dataset$A=="N",Dataset$A<-0,Dataset$A<-1)
虽然 ifelse 函数的结果是正确的，但是在打印变量时我得到了这个:
Although, the result from the ifelse function is correct but when printing the variable I m getting this:
"1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1"
"1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1"
"1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1"
"1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1"
"1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1"
"1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1"
"1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1"
"1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1"
你有什么提示吗?
推荐答案
将另一个变量 B 添加到数据集并使用 ifelse 函数，其中N"值为 0，Y"值为 1
Add another variable B to dataset and use ifelse function where you get 0 for "N"and 1 for "Y" values
Dataset$B <- ifelse(Dataset$A=="N",0,1)
或者您可以在与
Dataset$A <- ifelse(Dataset$A=="N",0,1)
