R: Examples for 'emmeans::fiber'

### ** Examples

fiber.lm <- lm(strength ~ diameter + machine, data=fiber)
ref_grid(fiber.lm)

'emmGrid' object with variables:
    diameter = 24.133
    machine = A, B, C

# Covariate-adjusted means and comparisons
emmeans(fiber.lm, pairwise ~ machine)

$emmeans
 machine emmean    SE df lower.CL upper.CL
 A         40.4 0.724 11     38.8     42.0
 B         41.4 0.744 11     39.8     43.1
 C         38.8 0.788 11     37.1     40.5

Confidence level used: 0.95 

$contrasts
 contrast estimate   SE df t.ratio p.value
 A - B       -1.04 1.01 11  -1.024  0.5781
 A - C        1.58 1.11 11   1.431  0.3596
