These functions take strings as input and turn them into symbols.
Contrarily to as.name(), they convert the strings to the native
encoding beforehand. This is necessary because symbols remove
silently the encoding mark of strings (see set_str_encoding()).
Usage
sym(x)
syms(x)
Arguments
x
A string or list of strings.
Value
A symbol for sym() and a list of symbols for syms().
# NOT RUN {# The empty string returns the missing argument:sym("")
# This way sym() and as_string() are inverse of each other:as_string(missing_arg())
sym(as_string(missing_arg()))
# }
