AddLeadingZeros: Add leading zeros to numbers while preserving other text

In SSBtools: Algorithms and Tools for Tabular Statistics and Hierarchical Computations

Add leading zeros to numbers while preserving other text

Description

This function is created to fix problems caused by a serious bug in Excel. Editing csv files in that program causes leading zeros to disappear.

Usage

AddLeadingZeros(
  codes,
  places,
  warningText = NULL,
  viaFactor = TRUE,
  nWarning = 6,
  removeLeadingTrailingWhitespace = TRUE
)

Arguments

codes	Character vector
places	Number of places for positive numbers. Minus sign is extra
warningText	When non-NULL, warning will be produced
viaFactor	When TRUE, the algorithm uses factor coding internally.
nWarning	Number of elements to be written before ... in warnings.
removeLeadingTrailingWhitespace	Remove leading and trailing whitespace

Value

Character vector
