Description Usage Arguments Value See Also Examples

To evaluate an expression such as "1+1", we need to apply two function iteratively. streaval() function is a simple wrapper around eval() and parse() functions.

1	streval(x)

`x`	A character vector with a single element that contains an expression.

Result of an evaluation of the expression contained in the string.

eval, parse

# create some expression
x <- "1+2"

# when evaluated it should produce 3
streval(x)

# streval() function has the same output as:
eval(parse(text=x))
