Generate Random Strings
Generates (pseudo)random strings of desired lengths.
stri_rand_strings(n, length, pattern = "[A-Za-z0-9]")
n |
single integer, number of observations |
length |
integer vector, desired string lengths |
pattern |
character vector specifying character classes to draw elements from, see stringi-search-charclass |
Vectorized over length and pattern.
If length of length or pattern is greater than n,
then redundant elements are ignored. Otherwise,
these vectors are recycled if necessary.
This operation may result in non-Unicode-normalized strings and may give peculiar outputs for bidirectional strings.
Sampling of code points from the set specified by pattern
is always done with replacement and each code point appears with equal
probability.
Returns a character vector.
