spread_

data

Strings giving names of key and value cols.

key_col,value_col

If there isn't a value for every combination of the other
variables and the key column, this value will be substituted.

fill

If <code>TRUE</code>, <code><a href="/link/type.convert?package=tidyr&version=0.2.0" rd-options="" data-mini-rdoc="tidyr::type.convert">type.convert</a></code> with
<code>asis = TRUE</code> will be run on each of the new columns. This is
useful if the value column was a mix of variables that was coerced to
a string.

convert

If <code>FALSE</code>, will keep factor levels that don't appear
in the data, filling in missing combinations with <code>fill</code>.

drop

An evolution of reshape2. It's designed specifically for data
    tidying (not general reshaping or aggregating) and works well with
    dplyr data pipelines.

spread_: Standard-evaluation version of `spread`.
