formats() functionThe 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.
fattr() functionThe 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().
The fmtr package contains several other functions for
setting attributes easily. These include the
descriptions(), widths() and
justification() functions to set 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().
NOTE: In version 1.5.8 of fmtr the
labels() function was moved to the common
package. If you wish to use this function, please include the
common package instead.
