Create a format catalog
A format catalog is a collection of formats. A format
collection allows you to manage and store formats as a unit. The
fcat function defines the format catalog.
fcat(...)
... |
A set of formats. Pass the formats as a name/value pair. Multiple name/value pairs are separated by a comma. |
A format catalog is an S3 object of class "fcat". The purpose of
the catalog is to combine related formats, and allow you to manipulate all
of them as a single object. The format catalog can be saved to/from a file
using the write.fcat and read.fcat functions.
A format catalog can also
be converted to/from a data frame using the as.fcat.data.frame
and as.data.frame.fcat functions. Formats are accessed in the
catalog using list syntax.
A format catalog may contain any type of format except a formatting list.
Allowed formats include a formatting string, a named vector lookup, a
user-defined format, and a vectorized formatting function. A formatting
list can be converted to a format catalog and saved independently. See the
flist function for more information on formatting lists.

condition(x == "B", "Label B"),

# Use formats in the catalog
fapply(2, c1$num_fmt)
fapply(c("A", "B", "C", "B"), c1$label_fmt)
fapply(Sys.Date(), c1$date_fmt)Please choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
