could not find function "rownames_to_column" Oops, I got an error message; the function wasn’t found. I remembered the right command, and using the dplyr package did cause the car names to vanish, but the solution is in the tibble package that I “forgot” to load. So let’s load...

dplyris an R package that provides a consistent set of verbs that help you solve the most common data manipulation problems, such as selecting variables based on the names, picking cases based on the values, reducing multiple values down to a single summary, and changing the ordering of the ...
Use a consistent naming scheme for the parameters (e.g.col_namesandcol_typesnotheaderandcolClasses). Are generally much faster (up to 10x-100x) depending on the dataset. Leave strings as is by default, and automatically parse common date/time formats. ...
As a side note, I'dreallyliketibble::rownames_to_columnto be able to runtype.convertin case there are no names or row names are otherwise numeric. It wouldn't be type-safe, but it could be put in as aconvert = TRUEparameter like that ofspreadandgather. I'd write the PR if the ...
