lfill
Syntax
lfill(obj)
Arguments
obj is a vector or a table with only numeric columns.
Details
If obj is a vector: linearly fill the NULL values between 2 non-NULL numeric values in obj.
If obj is a table with only numeric columns: for each column of the table, linearly fill the NULL values between 2 non-NULL numeric values.
lfill does not change obj, whereas lfill! changes obj.
Examples
$ a= NULL 1.5 NULL NULL 4.5
$ a.lfill();
[NULL,1.5,2.5,3.5,4.5]
