Dear Sir,

I’am a frensh student and i’am a new user of the R software.

After using the command (x<-read.delim(“clipboard”) to read a spreadsheet of 
Excel, I want to run the bds test and calculate the Lyapunov exponent. 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?

I thank you in advance and I’am waiting forward your e-mail
