rp.desc
(Package: rapportools) :
Descriptive Statistics
Aggregate table of descriptives according to functions provided in fn argument. This function follows melt/cast approach used in reshape package. Variable names specified in measure.vars argument are treated as measure.vars, while the ones in id.vars are treated as id.vars (see melt.data.frame for details). Other its formal arguments match with corresponding arguments for cast function. Some post-processing is done after reshaping, in order to get pretty row and column labels.

Calculates percentage of cases for provided variable and criteria specified in subset argument. Function accepts numeric, factor and logical variables for x parameter. If numeric and/or factor is provided, subsetting can be achieved via subset argument. Depending on value of na.rm argument, either valid (na.rm = TRUE) or all cases (na.rm = FALSE) are taken into account. By passing logical variable to x, a sum of (TRUE) elements is calculated instead, and valid percents are used (NA are excluded).

n
(Package: rapportools) :
Number of Cases
Returns the number of valid (non-NA) values in a variable. This is a wrapper around univar function with length function passed in fn argument, but with missing values previously removed. However, it's not possible to cancel NA omission with this function (doing so will yield error).
