[R] Help on np package - how to set the data into a panel format

[John Kane]

We really need to see the data, I think.

You can use the function dput(), see ?dput

dput(filename) will give you a formatted output that you can just  copy and paste into an e-mail. An R-help reader can just copy and paste that into R and have an exact copy of your data set.
