[R] Help with circular-linear regression in package circular
I am looking for assistance in figuring out how to use the circular-linear regression in package circular. See below for an example of what I have been trying. If anyone can help me with this please reply to my email address. Thank you, This is what I have been doing: with a linear variable x; lets use >x=c(1:10) and a circular variable y; for example >y=circular(c(123,239,265,342,198,253,343,237,162,247),units='degrees') trying to do the regression; >lm.circular(y,x, type='c-l') I get the error, >Error in lm.circular.cl(...) : 'init' is missing with no default But I tried to create a vector, init with the same columns as x (as the description of c-l regression says and I still get an error)>Error in lm.circular.cl(...) : 'init' must have the same number of elements as the columns of 'x'Any assistance is appreciated.
