A summaryFunction, intended to be called from summarize,
which calculates the 1st and 3rd quartiles of a variable. NA, NaN and Inf values are removed
prior to the computations.
Usage
quartiles(v, maxDecimals = 2)
Arguments
v
A variable (vector) of type numeric or integer.
maxDecimals
A positive integer or Inf. Number of decimals used when
printing numerical values in the data summary and in problematic values from the
data checks. If Inf, no rounding is performed.
Value
An object of class summaryResult with the following entries: $feature
("1st and 3rd quartiles"), $result (the 1st and 3rd quartiles of v) and
$value (the quartiles in their original format).
Details
The quartiles are computed using the quantile function from stats,
using type 7 quantiles for integer and numeric variables and type 1 quantiles for Date variables.
