as.orthogonal function error

MamtaMohan commented 2 years ago

Hi,

I am using onion package to generate set orthogonal matrices from quaternions.

I tried to convert a quaternion to an equivalent orthogonal matrix.

It gave me an error: Error in Re(q1) : non-numeric argument to function

I tried following sequence:

q1 <- rquat(1) q1 An object of class "quaternion" Slot "x": [,1] Re -0.7134218 i -1.0694264 j -1.4381244 k -0.6852207

as.orthogonal(q1) Error in Re(Q) : non-numeric argument to function

I tried example as mention in documentation as well. It also gave me an error.

as.orthogonal(rquat(q1)) Error in h(simpleError(msg, call)) : error in evaluating the argument 'z' in selecting a method for function 'Norm': error in evaluating the argument 'data' in selecting a method for function 'matrix': invalid arguments.

I would appreciate your response.

onion version 1.5-0:

as.orthogonal(rquat(1)) [,1] [,2] [,3] [1,] -0.2519797 -0.38107978 -0.8895417 [2,] -0.1238721 0.92434173 -0.3608990 [3,] 0.9597718 0.01925015 -0.2801205

I strongly suspect that you didn't load the package correctly as the print method was not invoked in the snippet you sent.

Thank you.

That was the problem.
