case+variable.names {stats} | R Documentation |
Simple utilities returning (non-missing) case names, and (non-eliminated) variable names.
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, ...)
object |
an R object, typically a fitted model. |
full |
logical; if |
... |
further arguments passed to or from other methods. |
A character vector.
lm
; further, all.names
,
all.vars
for functions with a similar name but only slightly
related purpose.

variable.names(lmxy)
variable.names(lmxy, full = TRUE) # includes the last
case.names(lmxy)
case.names(lmxy, full = TRUE) # includes the 0-weight case
