Complete

vec_detect_complete() detects "complete" observations. An observation is considered complete if it is non-missing. For most vectors, this implies that vec_detect_complete(x) == !vec_detect_missing(x).

For data frames and matrices, a row is only considered complete if all elements of that row are non-missing. To compare, !vec_detect_missing(x) detects rows that are partially complete (they have at least one non-missing value).

Usage

vec_detect_complete(x)

Arguments

x

A vector

Value

A logical vector with the same size as x.

Details

A record type vector is similar to a data frame, and is only considered complete if all fields are non-missing.

Examples

x <- c(1, 2, NA, 4, NA)

# For most vectors, this is identical to `!vec_detect_missing(x)`
vec_detect_complete(x)
#> [1]  TRUE  TRUE FALSE  TRUE FALSE
!vec_detect_missing(x)
#> [1]  TRUE  TRUE FALSE  TRUE FALSE

df <- data_frame(
  x = x,
  y = c("a", "b", NA, "d", "e")
)

# This returns `TRUE` where all elements of the row are non-missing.
# Compare that with `!vec_detect_missing()`, which detects rows that have at
# least one non-missing value.
df2 <- df
df2$all_non_missing <- vec_detect_complete(df)
df2$any_non_missing <- !vec_detect_missing(df)
