R:隐藏 lm 显示中的控制变量

Question

我想用 y 做线性回归作为我的因变量和 x1 x2 x3是我的自变量。我也有“控制”变量 z1 z2 z3我想包括但不显示结果。

summary(lm(y~x1+x2+x3+z1+z2+z3))

有没有办法让汇总不显示我的控制变量的系数？

正如@MrFlick 所建议的，使用 summary.lm 会有所帮助。

代码:

# Build Sample Data
df <- data.frame(y = rnorm(100), x1 = rnorm(100), x2 = rnorm(100), x3 = rnorm(100), z1 = rnorm(100), z2 = rnorm(100), z3 = rnorm(100))

# Run Model
sum <- summary.lm(lm(y ~ x1 + x2 + x3 + z1 + z2 + z3, data = df))

# Remove z1:z3
sum$coefficients <- sum$coefficients[1:4,]

# Print Results
print(sum)

输出 :

Call:
lm(formula = y ~ x1 + x2 + x3 + z1 + z2 + z3, data = df)
