diff in a dataframe
...the first row of these columns cannot be computed, but can I coerce this to happen and assign a missing value there? It would be really great if I could do that, because in this case I don't have to re-index my transformed series to the dates again in a new dataframe. Thanks in anticipation. Vishal Belsare

anyone using LARS package in R
...anyone used the "Lars" package in R before? If so, is there any tutorial (not manual) or worked out example online for this R package that one can go through to figure out how one can use this package with lasso regression? I appreciate any help I can get in this direction.
