Simple, Consistent Wrappers for Common String Operations stringr provide fast, correct implementations of common string manipulations. stringr focusses on the most important and commonly used string manipulation functions whereas stringi provides a comprehensive set covering almost anything you can imagine.

.NET clr function exports
html	comvert any object to html text document
toString	Convert an R Object to a Character String This is a helper function for format to produce a single character string describing an R object.
loadJSON
loadXml	load a .NET object from the xml data file
xml	Convert most of the R# object or VB.NET object to xml document string.
bdecode
bencode
json	Convert most of the R# object or VB.NET object to json string.
base64	encode byte stream or text content into base64 string
base64_decode	decode base64 string as text or the raw bytes buffer object.
urldecode	Decodes URL-encoded string Decodes any `%##` encoding in the given string. Plus symbols ('+') are decoded to a space character.
grep
nchar	Count the Number of Characters (or Bytes or Width) nchar takes a character vector as an argument and returns a vector whose elements contain the sizes of the corresponding elements of x.
regexp	Initializes a new instance of the `RegularExpression` class for the specified regular expression `pattern`.
regex_match	Searches the specified input string for the first occurrence of the regular expression specified in the System.Text.RegularExpressions.Regex constructor.
sprintf	Use C-style String Formatting Commands A wrapper for the C function sprintf, that returns a character vector containing a formatted combination of text and variable values.
str_trim	Remove whitespace strtrim() removes whitespace from start and end of string; strsquish() removes whitespace at the start and end, and replaces all internal whitespace with a single space.
str_squish	Remove whitespace strtrim() removes whitespace from start and end of string; strsquish() removes whitespace at the start and end, and replaces all internal whitespace with a single space.
paste0	Concatenate Strings Concatenate vectors after converting to character. Concatenation happens in two basically different ways, determined by collapse being a string or not. `paste0(..., collapse)` is equivalent to `paste(..., sep = "", collapse)`, slightly more efficiently.
str_pad	Pad A String.
str_empty	test of the give character vector is empty string or not
tagvalue	parse the string text in format like `tag{delimiter}value`
tolower	Character Translation and Casefolding Translate characters in character vectors, in particular from upper to lower case or vice versa.
toupper
concatenate
chr	`chr` returns the characters corresponding to the specified ASCII codes.
charAt
substr	Substrings of a Character Vector Extract or replace substrings in a character vector.
str_replace	Pattern Matching and Replacement
random_str	generate random string which is all consist with ascii chars.
text_equals	check of the text equals between two character vector.
text_grep	apply for batch text grep/trimming/strip
