Error in x$e : $ operator is invalid for atomic vectors

问题：

解决：

完整错误：

问题：

#define vector
x <- c(1, 3, 7, 6, 2)#provide names
names(x) <- c('a', 'b', 'c', 'd', 'e')#attempt to access value in 'e'
x$e

解决：

#查看类型

#check if vector is atomic
is.atomic(x)[1] TRUE

#[[]]索引

#define vector
x <- c(1, 3, 7, 6, 2)#provide names
names(x) <- c('a', 'b', 'c', 'd', 'e')#access value for 'e'
x[['e']]

#使用getElement函数

#define vector
x <- c(1, 3, 7, 6, 2)#provide names
names(x) <- c('a', 'b', 'c', 'd', 'e')#access value for 'e'
getElement(x, 'e')

#把向量变为dataframe

#define vector
x <- c(1, 3, 7, 6, 2)#provide names
names(x) <- c('a', 'b', 'c', 'd', 'e')#convert vector to data frame
data_x <- as.data.frame(t(x))#access value for 'e'
data_x$e

完整错误：
