I have charged the R software by the packages tseries and tseriesChaos. when i run bds.test(x,m=2) Unfortunately the R software displays “error in as.vector(x,mode= “double”) : the object (list) can not be automatically converted on double” so what shall I do to run this two tests(lyapunov and bds)? And what is my mistake?

seems that the data import failed. probably the exported excel data are 
not in a format accepted correctly by read.delim. check this.


alternative (maybe): there is an additional package 'gdata' on CRAN 
which you can download and install. it contains a function

read.xls

which can read directly the excel binary format (with some limitations).
