已经从dta文件中提取了数据但是怎么取到一列数据作为向量呢
> my_data<-read.dta("C:/Users/sunch/Desktop/demographic_background.dta")
> barplot(my_data$ba001)
Error in barplot.default(my_data$ba001) : 'height'要么是向量，要么是矩阵

> barplot(my_data[,"ba001"])
Error in barplot.default(my_data[, "ba001"]) :
'height'要么是向量，要么是矩阵

这样也不行

> c<-as.vector(my_data[,"ba001"])
> barplot(c)
Error in -0.01 * height : 二进列运算符中有非数值参数

又成这样了。。。
