In dtkaplan/checkr: Facilities for checking R submissions in tutorials

Description

Check that argument is in radians

Usage

trig_radian_check(ex, radian_val,
  message = "Could not find call to a trigonometric function", eps = 0.001)

Arguments

ex	A checkr_result, presumably containing a call to a trig function.
radian_val	a number: the desired angle in radians
message	character string message to produce on failure
eps	precision of comparison

Examples

ex <- for_checkr(quote(15 * sin(3)))
trig_radian_check(ex, 3)
trig_radian_check(ex, 3 * pi / 180)
trig_radian_check(ex, 4*pi/180)
