(count-missing col)Returns the number of missing values in column col.
Returns the number of missing values in column `col`.
(drop-missing col)Remove missing values from column col.
Remove missing values from column `col`.
(replace-missing col)(replace-missing col strategy)(replace-missing col strategy value)Replace missing values in column col with give strategy.
Strategies may be:
:down - Take the previous value, or use provided value.:up - Take the next value, or use provided value.:downup - Take the previous value, otherwise take the next value.:updown - Take the next value, otherwise take the previous value.:nearest - Use the nearest of next or previous values. (Strategy :mid is an alias for :nearest).:midpoint - Use the midpoint of averaged values between previous and next (non-missing) values.:abb - Impute missing value with approximate Bayesian bootstrap.
See r's ABB.:lerp - Linearly interpolate values between previous and next nonmissing rows.:value - Provide a value explicitly. Value may be a function in which
case it will be called on the column with missing values elided
and the return will be used to as the filler.Replace missing values in column `col` with give `strategy`.
Strategies may be:
- `:down` - Take the previous value, or use provided value.
- `:up` - Take the next value, or use provided value.
- `:downup` - Take the previous value, otherwise take the next value.
- `:updown` - Take the next value, otherwise take the previous value.
- `:nearest` - Use the nearest of next or previous values. (Strategy `:mid` is an alias for `:nearest`).
- `:midpoint` - Use the midpoint of averaged values between previous and next (non-missing) values.
- `:abb` - Impute missing value with approximate Bayesian bootstrap.
