Case and Variable Names of Fitted Models

Simple utilities returning (non-missing) case names, and (non-eliminated) variable names.

Keywords
models, regression
Usage
case.names(object, ...)
## S3 method for class 'lm':
case.names(object, full = FALSE, \dots)

variable.names(object, ...) ## S3 method for class 'lm': variable.names(object, full = FALSE, \dots)

Arguments
object
an Robject, typically a fitted model.
full
logical; if TRUE, all names (including zero weights, ...) are returned.
...
further arguments passed to or from other methods.
Value

  • A character vector.

Examples
library(stats) x <- 1:20 y <- setNames(x + (x/4 - 2)^3 + rnorm(20, sd = 3), paste("O", x, sep = ".")) ww <- rep(1, 20); ww[13] <- 0 summary(lmxy <- lm(y ~ x + I(x^2)+I(x^3) + I((x-10)^2), weights = ww), cor = TRUE) variable.names(lmxy) variable.names(lmxy, full = TRUE) # includes the last case.names(lmxy) case.names(lmxy, full = TRUE) # includes the 0-weight case
