Generate random strings

Generate a vector of random alphanumeric strings each of an arbitrary length.

.rndstr(n = 1, len = 8)

rndstr(n, len, characterFirst)

# S4 method for class 'numeric,numeric,logical'
rndstr(n, len, characterFirst)

# S4 method for class 'numeric,numeric,missing'
rndstr(n, len)

# S4 method for class 'numeric,missing,logical'
rndstr(n, characterFirst)

# S4 method for class 'missing,numeric,logical'
rndstr(len, characterFirst)

# S4 method for class 'numeric,missing,missing'
rndstr(n)

# S4 method for class 'missing,numeric,missing'
rndstr(len)

# S4 method for class 'missing,missing,logical'
rndstr(characterFirst)

# S4 method for class 'missing,missing,missing'
rndstr(n, len, characterFirst)

Arguments

n

Number of strings to generate (default 1). Will attempt to coerce to integer value.

len

Length of strings to generate (default 8). Will attempt to coerce to integer value.

characterFirst

Logical, if TRUE, then a letter will be the first character of the string (useful if being used for object names).

Value

Character vector of random strings.
