case/variable.names {stats}
Case and Variable Names of Fitted Models
Description
Simple utilities returning (non-missing) case names, and (non-eliminated) variable names.
Usage
case.names(object, ...) ## S3 method for class 'lm': case.names((object, full = FALSE, ...) variable.names(object, ...)) ## S3 method for class 'lm': variable.names((object, full = FALSE, ...))
Arguments
- object
- an R object, typically a fitted model.
- full
- logical; if
TRUE, all names (including zero weights, ...) are returned. - ...
- further arguments passed to or from other methods.
Values
A character vector.
See Also
lm; further, all.names, all.vars for functions with a similar name but only slightly related purpose.
Examples
x <- 1:20 y <- x + (x/4 - 2)^3 + rnorm(20, sd=3) names(y) <- 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
