我需要从数据框中排除变量“PABI”。所以，我按如下方式进行子集化：
MyData4 <- subset(MyData, PROV=="PABI")
newdata <- MyData[!MyData4]
但我得到了这个错误：
Error in FUN(left) : invalid argument type
In addition: Warning messages:
1: In Ops.factor(left) : ‘!’ not meaningful for factors
2: In Ops.factor(left) : ‘!’ not meaningful for factors
3: In Ops.factor(left) : ‘!’ not meaningful for factors
4: In Ops.factor(left) : ‘!’ not meaningful for factors
5: In Ops.factor(left) : ‘!’ not meaningful for factors
6: In Ops.factor(left) : ‘!’ not meaningful for factors
7: In Ops.factor(left) : ‘!’ not meaningful for factors
8: In Ops.factor(left) : ‘!’ not meaningful for factors
为什么不直接做：
newdata <- subset(MyData, PROV!="PABI")
