Convenience Functions

The formats() function

The formats associated with a data frame can be easily extracted or assigned with the formats() function. This function returns or accepts a named list of formatting objects. The names of the list items correspond to the names of the columns in the data frame. This function is useful when you want to assign formats to many columns.

The fattr() function

The fattr() function helps assign formatting attributes to a vector or data frame column. The fattr() function can assign the format, label, description, width, and justify attributes all at once. These attributes are passed in as arguments to the fattr() function, instead of as properties on a call to attr().

Other convenience functions

The fmtr package contains several other functions for setting attributes easily. These include the labels(), descriptions(), widths() and justification() functions to set column labels, columns descriptions, column widths, and column justification on an entire data frame. The package also includes class testing functions like is.format() and is.flist().
