Hello..
How do I get str() to show all variables in a data frame? It seems to be
"list output truncated" at about 99 variables, the data frame has over
600 but i can't seem to figure out how to show all variables, we see
list.len() but again can't seem to figure this out - help will be

We should really have an R package rating site, comments, reviews or

implemented.

Hello, can one use predict, as you can with other model objects like lm,
with dynlm to predict a new data set that is identical in field names,
just a different time period.
Be nice if you could, I don't really want to create a new data set with
all the lags, hoping it would generate dynamically.
