使用用rjava方式用java调用R语言,用 Rengine 接收这样一个list ,结果里面的字符值全部变成了数字,这是为什么? java debug 结果如下

[VECTOR ([FACTOR {levels=("1","14","15","16","17","18","19"),ids=(0,0,0,0,0,0)}], [FACTOR {levels=("1","14","15","16","17","18","19"),ids=(3,1,4,2,6,5)}], [REAL* (0.993164292197223, 0.9798671822279136, 0.9732088580695736, 0.9701674411051808, 0.9694019685310229, 0.9093259401814968)])]
