delLCP {PTXQC}

Removes the longest common prefix (LCP) from a vector of strings.

Description

You should provide only unique strings (to increase speed). If only a single string is given, the empty string will be returned unless minOutputLength is set.

Usage

delLCP(x, min_out_length = 0, add_dots = FALSE)

Arguments

x

Vector of strings with common prefix

min_out_length

Minimal length of the shortest element of x after LCP removal [default: 0, i.e. empty string is allowed] . If the output would be shorter, the last part of the LCP is kept.

add_dots

Prepend output with '..' if shortening was done.

Value

Shortened vector of strings

Examples

  delLCP(c("TK12345_H1"), min_out_length=0)
  ## ""

  delLCP(c("TK12345_H1"), min_out_length=4)
  ## "5_H1"

  delLCP(c("TK12345_H1"), min_out_length=4, add_dots = TRUE)
  ## "..5_H1"

  delLCP(c("TK12345_H1", "TK12345_H2"), min_out_length=4)
  ## "5_H1" "5_H2"

  delLCP(c("TK12345_H1", "TK12345_H2"), min_out_length=4, add_dots = TRUE)
  ## "..5_H1" "..5_H2"

  delLCP(c("TK12345_H1", "TK12345_H2"), min_out_length=8)
  ## "12345_H1", "12345_H2"

  delLCP(c("TK12345_H1", "TK12345_H2"), min_out_length=8, add_dots = TRUE)
  ## "TK12345_H1", "TK12345_H2" (unchanged, since '..' would add another two)

  delLCP(c("TK12345_H1", "TK12345_H2"), min_out_length=60)
  ## "TK12345_H1", "TK12345_H2" (unchanged)

  delLCP(c("TK12345_H1", "TK12345_H2"), min_out_length=60, add_dots = TRUE)
  ## "TK12345_H1", "TK12345_H2" (unchanged)
