as.data.frame.disk.frame

Convert disk.frame to data.frame by collecting all chunks

A disk-based data manipulation tool for working with
large-than-RAM datasets. Aims to lower the barrier-to-entry for
manipulating large datasets by adhering closely to popular and
familiar data manipulation paradigms like 'dplyr' verbs and
'data.table' syntax.

<dd>a disk.frame</dd>
<dt>row.names</dt>
<dd>NULL or a character vector giving the row names for the data frame. Missing values are not allowed.</dd>
<dt>optional</dt>
<dd>logical. If TRUE, setting row names and converting column names (to syntactic names: see make.names) is optional. Note that all of R's base package as.data.frame() methods use optional only for column names treatment, basically with the meaning of data.frame(*, check.names = !optional). See also the make.names argument of the matrix method.</dd>
