Airon,
I don't think you have to find an English computer 'cause the
following must work in your Chinese one :-)
Let me explain. First of all, change your lines to
xdata <- ckhdat$Adj..Close[1:1447]
#names(ckhdwt.la8) <- c("w1", "w2", "w3", "w4", "w5","w6", "v6")
note the # sign, i.e., DO NOT change the names before
the function imodwt.
This is because the function imodwt looks for the names
created by the modwt function. If you need to change names,
do it AFTER the reconstruction.
I hope that it helps you.
Rogerio
