str.split.at.pos: Splits a single string str at positions specified by pos

In skranz/stringtools: Tools for working with strings in R

Splits a single string str at positions specified by pos

Description

Splits a single string str at positions specified by pos

Usage

## S3 method for class 'split.at.pos'
str(str, pos, keep.pos = FALSE, compl = NULL,
  max.char = max(nchar(str)), pos.mat.like.list = FALSE)

Arguments

str	character vector that shall be splitted
pos	split positions can be vector: assuming an element of size 1 that specifies a single char at that positions n*2 matrix: first column left position, right column right position list of vectors or matrices, specifying different pos for different str
keep.pos	default=FALSE. If TRUE add the tokens that describe the split to the result otherwise remove them

Value

single return is length of pos (if vector) or NCOL(pos) if pos is matrix

Examples

## Not run: 
  str = c("1234567890")
  pos = c(3,5,7)
  str.split.at.pos(str,pos,keep.pos = FALSE)
  str.split.at.pos(str,pos,keep.pos = TRUE)
  pos = rbind(c(2,3),c(5,5),c(7,9))
  str.split.at.pos(str,pos,keep.pos = FALSE)
  str.split.at.pos(str,pos,keep.pos = TRUE)
  
  # Multiple str
  str = c("Hello ernie","abcg","hello erna")
  pos = c(2,5,8)
  str.split.at.pos(str,pos,keep.pos=TRUE)
  pos = list(c(3,5),c(2),c(1,9))
  str.split.at.pos(str,pos,keep.pos=TRUE)
    
  str = c("Hello ernie","abcdefg","hello erna")
  pos = str.locate.first(str,"e",ignore=ignore)
  pos
  str.split.at.pos(str,pos,keep.pos=TRUE,pos.mat.like.list=FALSE)
  str.split.at.pos(str,pos,keep.pos=TRUE,pos.mat.like.list=TRUE)
