Stringendo - a string parsing library

String parsing functionalites for generating plotnames, filenames and path. Used by most of my other packages, including CodeAndRoll2 and ggExpress. Many functionalities were part of the formerly used CodeAndRoll (v1).

Installation

Install directly from GitHub via devtools with one R command:

# install.packages("devtools"); # If you don't have it.
require("devtools")
devtools::install_github(repo = "vertesy/Stringendo")

...then simply load the package:

require("Stringendo")

Alternatively, you simply source it from the web. This way function help will not work, and you will have no local copy of the code on your hard drive.

source("https://raw.githubusercontent.com/vertesy/Stringendo/main/R/Stringendo.R")

Troubleshooting

If you encounter a bug, something doesn't work or unclear, please let me know by raising an issue on Stringendo – Please check if it has been asked.

List of Functions in Stringendo.R (67)

Updated: 2024/10/24 11:02

• 1 stopif()

Stop execution if condition is TRUE. The stopif() function stops the execution if the condition is TRUE. It is the opposite of stopifnot(), which stops if the condition is not TRUE. This function is useful to increase clarity in the code by removing double negations.

• 2 warnifnot()

Issue warnings if conditions are not TRUE. The warningifnot() function checks whether each condition passed to it is TRUE. If any condition is not met, a warning is issued but the execution continues. This is similar to stopifnot(), which throws an error and halts execution, but warningifnot() only issues a warning, allowing the program to proceed.

• 3 warnif()

Issue a warning if condition is TRUE. The warnif() function issues a warning if the condition is TRUE. It is the opposite of warningifnot(), which warns if the condition is not TRUE. This function is useful for issuing warnings when a certain condition is met.

• 4 testNumericCompatible()

Test if a Variable is Inherently Numeric ('0.1' as numeric). This function checks if a given variable is inherently numeric. It returns TRUE if the variable can be converted to a numeric value without loss of information and is not inherently a character string, otherwise it returns FALSE.

• 5 "%!in%"()

Negation of the in (w. grapes) operator. %!in% is used to test if elements of one vector are not present in another vector. It is the negation of the %in% operator. This operator returns TRUE for elements of x that are not in y.

• 35 kpwNames()

Collapse and paste Elements With Names. This function takes a named vector and returns a string where each element is pasted with its name. Elements are separated by a specified string, and name-element pairs are also separated by a specified string. The default named vector is c('a' = 1, 'b' = 2).

• 36 kollapse()

Kollapse. Collapses values and strings to one string (without a white space). It also prints the results (good for a quick check)
