First a general comment on posting style, could you please be more specific about where the error occurs as without this it is very difficult to identify what the problem is. Now concerning your problem. When I tried the code I posted yesterday I thought it worked fine.

Dear R experts, Might be very simple question to ask but would be insightful. As the same story of nested "for loops". following is the code that I am using to get the autocorrelation function of the sample data.

I am not sure if comparing p-values IS the way even though the probability of seeing such "weird" observation under H0

Dear R users! I am using R Version 1.7.1, Windows XP, package "foreign" (Version: 0.6-1), SPSS 11.5.1. There is one thing I noticed with "read.spss", and I'd like to ask if this is considered to be a feature, or possibly a bug: When reading character columns, character strings seem to get filled with blanks at the end. Simple example: In SPSS, create a file with one
