seqLength: Determine lengths of sequences of identical elements
Description
The function returns a vector indicating the length of sequences of identical
elements or elements of an identical type in a vector.
Usage
seqLength(array_in, funct.seq = is.na)
Arguments
array_in
numeric: input vector
funct.seq
string or name of a function: name of the function to use. Has to return
TRUE for elements belonging to the sequence and FALSE otherwise
Value
for each single element
Details
The function returns a vector of the same length as the input vector indicating
for each element in array_in how long the sequence of similar elements this value
belongs to id. Zero indicates that identical values (or types) in the neighbourhood
of the value. This process helps to indicate for
example long gaps in timeseries.
