Identify the observations that contain a specific value in a logical map
# S3 method for LogMap
labels(
object,
values,
select = c("first", "last", "common", "all"),
simplify = TRUE,
...
)labels: A list, or vector if simplify is TRUE,
of all values and the observations they're found in, according
to the value of select
A LogMap object
A vector of values to find observations for
Observation selection method; choose from:
“first”: the first observation the value is found in
“last”: the last observation the value is found in
“common”: the first most-common observation the value
is found in; most-common is determined by the observation that contains
the most of the values requested
“all”: all observations the value is found in
Simplify the resulting list to a vector
