{poorman} 0.2.5

Yesterday I released the ninth version of {poorman} to CRAN.

This update has added the following new features:

• summarise() can now revise grouping structures with the .groups argument (#57).
• group_by() can now drop groups formed by factor levels that don’t appear in the data with the .drop parameter (#63).
• New cumulative functions have been added: cumall(), cumany() and cummean() (#64).
• Additional tools for working with rownames have been added: has_rownames(), remove_rownames(), column_to_rownames(), rowid_to_column() (#66).
• filter() gains the .preserve parameters (#81).
• if_any() and if_all() were added (#80).

The following fixes were also implemented:

• mutate() now successfully evaluates functions defined in the scope of a parent function (#68).
• select_positions() now works if passed a combination of positive and negative values (#71).
• transmute() now keeps unnamed columns that it creates (#72).

The following refactorisations took place:

• When grouping data with group_by(), it will now create an object of class grouped_df and not grouped_data which keeps it consistent with the {dplyr} method name (#70). This should hopefully make transitioning packages from {dplyr} to {poorman} a little easier.
