There are different packages in R to fit an ARIMA model. I would use the

In your case, perhaps you would want to explore SARIMA models to include

If there isn't multiple sheets you can use the 'gdata' package and
read.xls().
Otherwise you could re-save the file as a csv file and load that file with
read.csv() assuming not multiple sheets again which a csv cannot contain.

Do not post HTML. Why you did not populate your list directly with coefficients
by let say coef(lm.result)?
Anyway, you can reveal structure of individulal list component by

sapply/lapply probably with rbind.

There is some confusion in your postings, as in your first posting the models
were GLM's but with the default gaussian family (not binomial) since the
'family' argument was not present in the glm() call and in the second post you
have references to clm() which is for ordinal response

There is no argument 'test' to anova.clm hence the error message.
The likelihood ratio statistic (or, alternatively, G^2 statistic or
