Arguments

text.var

The text variable.

A character vector of grouped word terms to insert a new separating/space character.

sep

A character string to separate the terms.

rm.extra

logical. Should trailing, leading and > 1 continuous white spaces be removed?

ignore.case

logical. If FALSE, the pattern matching is case sensitive and if TRUE, case is ignored during matching.

Details

space_fill is useful for keeping grouped words together. Many functions in qdap take a char.keep or char2space argument. This can be used to prepare multi word phrases (e.g., proper nouns) as a single unit.

Examples

x <- c("I want to hear the Dr. Martin Luther King Jr. speech.",
    "I also want to go to the white House to see President Obama speak.")

keeps <- c("Dr. Martin Luther King Jr.", "The White House", "President Obama")
space_fill(x, keeps)
strip(space_fill(x, keeps))
