Greetings of Peace!

I am new in R software. I want to use the correlation dimension corrDim in computing a map. I have installed the packages(fractal) in R. Now my problem is this, when I tried your example in the following site http://rgm2.lab.nig.ac.jp/RGM2/func.php?rd_id=fractal:corrDim 
> library(fractal)
> png(filename="corrDim_%03d_med.png", width=480, height=480)
> beam.d2 <- corrDim(beamchaos, olag=10, dim=10, res=4)
Warning messages:
1: In any(diff(x)) : coercing argument of type 'double' to logical
2: In any(diff(x)) :
 coercing argument of type 'double' to logical
3: In any(diff(x)) : coercing argument of type 'double' to logical
4: In any(diff(x)) : coercing argument of type 'double' to logical
5: In any(diff(x)) : coercing argument of type 'double' to logical
6: In any(diff(x)) : coercing argument of type 'double' to logical
7: In any(diff(x)) : coercing argument of type 'double' to logical
8: In any(diff(x)) : coercing argument of type 'double' to logical
9: In any(diff(x)) : coercing argument of type 'double' to logical
10: In any(diff(x)) : coercing argument of type 'double' to logical
  I cannot proceed because of the warning messages appeared. Is my installation correct? 

Please HELP me..

Thank you so much.
