I\'m curious to know if R can use its eval() function to perform calculations provided by e.g. a string.

This is a common case:

eval(\"5

    You can use the parse() function to convert the characters into an expression. You need to specify that the input is text, because parse expects a file by default:

    eval(parse(text="5+5"))
