从 JRI 返回系数参数

Question

我正在尝试通过 JRI 运行 R 汇总命令以获得多元线性回归的结果

result <- lm(Performance Score ~ Department+Grade,data = StudentData)
summary(result)

Call:
lm(formula = Performace.Score ~ Department + Grade, data = tree)

Residuals:

-1.0146 -0.8472  0.1206  0.1528  1.3193

现在，当我尝试通过 JRI 运行相同的命令并尝试仅获取相同数据的系数时，将获取以下结果：

根据我从 JRI 得到的上述结果，我只会获取系数值，而不是像我们在 R 控制台中得到的参数（在这种情况下是部门列表和等级）。

如何获取系数值和参数。

你试过 asList() 函数吗？
