Airon,

I used R2.4.0 on a Windows XP (SP2) (not Chinese :-))
and it still works:

> data = read.csv("u:/airon.csv")
> xdata = data$Adj..Close
> modwt.la8 = modwt(xdata, "la8", n.level=6)
> summary(modwt.la8)
   Length Class  Mode   
d1 1467   -none- numeric
d2 1467   -none- numeric
d3 1467   -none- numeric
d4 1467   -none- numeric
d5 1467   -none- numeric
d6 1467   -none- numeric
s6 1467   -none- numeric
> ydata = imodwt(modwt.la8)
> summary(ydata)
   Min. 1st Qu.  Median    Mean 3rd Qu.    Max. 
  37.35   57.56   67.93   67.31   78.32  104.90 
> max(ydata-xdata)
[1] 2.957279e-11

Can you provide a simple program and the resulting
messages showing that it doesn't work?

Rogerio.
