Package 'piamutils'

Delete "+" in Variable Names. Optionally Save in File with Suffix "_withoutPlus"

Description

The function can take a multiple of input formats. It replaces "|+|", "|++|", "|+++|", ... by "|" in variable names and in this "deletes" the "plus-notation".

Usage

deletePlus(mif, writemif = FALSE)

Arguments

mif	A path to a mif-file (might be created by confGDX2MIF), a magpie object containing reporting, a quitte object, or a character vector or factor of variable names.
writemif	A single truth value. Only used when mif is a file path. Should the new mif with the adjusted names be saved? If yes the new name will have the suffix "_withoutPlus.mif".

Value

If mif is a file path and writemif is FALSE, a MAgPIE object. If mif is not a file path the result is the object mif with replaced variable names.

Examples

deletePlus(c(
  "ab|cd", # "ab|cd"
  "de|+|fgh", # "de|fgh"
  "i|j|++|k|l|++++|mno|p", # "i|j|k|l|mno|p"
  "++|q+|+r|+p+|u+v|+", # "++|q+|+r|+p+|u+v|+"
  "w|+|+|x")) # "w|x"

Arguments

x	A path to a mif-file (might be created by confGDX2MIF), a magpie object containing reporting, a quitte object, or a character vector or factor of variable names.
modify	A function that modifies a character vector.
writeMifSuffix	NULL or a suffix for the file name if the result should be written as a mif-file.
...	Further arguments for the modify function.

Substitute Placeholders in Variable Names.

Description

Substitute Placeholders in Variable Names.

Usage

substitutePlaceholder(x, writeMifSuffix = NULL, substitutions = c(. = "$dot$"))

Arguments

x	A path to a mif-file (might be created by confGDX2MIF), a quitte object, or a character vector or factor of variable names.
writeMifSuffix	NULL or a suffix for the filename if the result should be written as a mif-file.
substitutions	A named character vector of placeholders with replacements as names.

Value

If x is not a file path the result is the object x with replaced variable names.

Examples

substitutePlaceholder(c(
  "3$dot$5", # "3.5"
  "3$dot5", # "3$dot5"
  "3.5", # "3.5"
  "$dot$dot$dot$dot$dot$")) # ".dot.dot."
