adjustUnitPrefix: Adjust Value With Different Decimal Prefixes To Single Prefix Plus Unit

Description

This function provides help converting values with with different unit-prefixes to a single prefix-unit type. This can be used to convert a vector of mixed prefixes like 'p' and 'n'. Any text to the right of the unit will be ignored.

Usage

adjustUnitPrefix(
  x,
  pref = c("z", "a", "f", "p", "n", "u", "m"),
  unit = "sec",
  sep = c(".", " ", ""),
  headingTxt = "",
  silent = FALSE,
  debug = FALSE,
  callFrom = NULL
)

Value

This function returns a numeric vector with quantities extracted and adjusted to a single type of unit (without the unit description)

Arguments

x: (character) vector containing digit uunit-prefix and unit terms
pref: (character) multiplicative unit-prefixes, assumes as increasing factors of 1000
unit: (character) unit name, the numeric part may be sepatated by one space-character
sep: (character) separator characters that may appear between integer numeric value and unit description
headingTxt: (character) additional text preceeding the numeric part of 'x' to be ingnored/removed
silent: (logical) suppress messages
debug: (logical) additional messages for debugging
callFrom: (character) allow easier tracking of messages produced

Details

Please note that the current version recognizes and converts only interger values, decimals or scientific writing won't work. The resultant numeric vector expresses all values as lowest prefix unit level. In case of invalid entries NAs will be returned.

Please note the 'u' is used for 'micro'.

Examples

Run this code

adjustUnitPrefix(c("10.psec abc","2 fsec etc"), unit="sec")
