Apply Functions Over 'dust_list' Objects


The sprinkle methods work with dust_list objects very naturally, but medleys pose a slightly more difficult problem. Medleys are intended to be predefined collections of sprinkles that reduce the time required to format a table with a particular look and style. It seems counter-productive to expect a user to define each of her or his medleys as a method that can work with both dust and dust_list objects. pixieply is a wrapper to lapply that preserves the dust_list class of the object.

pixiemap provides functionality to apply differing sprinkles over each element of a dust_list. The most common example is probably adding a unique caption to each table.


pixieply(X, FUN, ...)

pixiemap(X, FUN, ..., MoreArgs = NULL, SIMPLIFY = FALSE, USE.NAMES = TRUE)



An object of class dust_list.


A function to apply to each element of X


Additional arguments to pass to FUN


a list of other arguments to FUN


logical or character string; attempt to reduce the result to a vector, matrix or higher dimensional array; see the simplify argument of sapply


logical; use names if the first ... argument has names, or if it is a character vector, use that character vector as the names.
