Return a logical vector indicating which cases are complete, i.e., have no missing values.
complete.cases(…)a sequence of vectors, matrices and data frames.
A logical vector specifying which observations/rows have no missing values across the entire sequence.
# NOT RUN {
x <- airquality[, -1] # x is a regression design matrix
y <- airquality[, 1] # y is the corresponding response
stopifnot(complete.cases(y) != is.na(y))
ok <- complete.cases(x, y)
sum(!ok) # how many are not "ok" ?
x <- x[ok,]
y <- y[ok]
