statistics - Rayleigh's Test for of Uniformity in R -

i try rayleigh's test circadian rhythm in r.

dec_day_time decimal day time 1.0 = 24 hours.

my data looks that:

dec_day_time calc_active 1  0.240972222     resting 2         0.25     resting 3  0.258333333     resting 4  0.259027778      active 5  0.259722222     resting 6  0.265277778     resting 

these first 10 columns example:

dec_day_time<-c(0.240972222,0.25,0.258333333,0.259027778,0.259722222,0.265277778,0.265277778,0.265972222,0.268055556,0.270833333) calc_active<-c("resting","resting","resting","active","resting","resting","active","active","active","resting") 

i try way:

actres<-data.frame(calc_active,dec_day_time) rayleigh.test(x=actres,mu=circular(1)) 

but error:

error in x%%(ang * pi) : non-numeric argument binary operator

do somehow have calculate angle or something? couldn't find examples in internet.

any appreciated.

solved problem:

i calculated angle in degrees default radians.

there rayleigh test in package circstats parameter degree=true

active.with.na<-degrees_day_time[calc_active=="active"] active.without.na<-active.with.na[!is.na(active.with.na)] # remove nas r.test(x=active.without.na,degree=true) 

output:

r.bar [1] 0.4790981  $p.value [1] 1.009254e-33
