This array is useful for extracting the subset of complete cases. The function
cci(x) is equivelant to complete.cases(x).
Missing values in x are coded as NA. The companion function
for selecting the incomplete cases is ici().
Usage
cci(x)
Arguments
x
An R object. Currently supported are methods for the
following classes: mids, data.frame and matrix. In
addition, x can be a vector of any kind.
Value
Logical vector indicating the complete cases,
. If x is a data.frame or
matrix the length is nrow(x). In other cases,
the length is length(x).
cci(nhanes) # indicator for 13 complete cases f <- cci(nhanes[,c("bmi","hyp")]) # complete data for bmi and hyp nhanes[f,] # obtain all data from those with complete bmi and hyp
