Handle missing values with a warning
This NA handler ensures that those models that support the
na.action
parameter do not silently drop missing values. It
wraps around stats::na.exclude()
so that there is one
prediction/residual for input row. To apply it globally, run
options(na.action = na.warn)
.
na.warn(object)

A data frame |
df <- tibble::tibble( x = 1:10, y = c(5.1, 9.7, NA, 17.4, 21.2, 26.6, 27.9, NA, 36.3, 40.4) ) # Default behaviour is to silently drop m1 <- lm(y ~ x, data = df) resid(m1) # Use na.action = na.warn to warn m2 <- lm(y ~ x, data = df, na.action = na.warn) resid(m2)
