[R] plspm package error in data frame

[Bert Gunter]

You need to first go through a basic tutorial to learn basic R
constructs and functionality. IMHO, fooling around with special
packages before you learn the basics is a bad strategy. Packages
generally assume you know the basics.

Some tutorial recommendations can be found here:

But just googling around the web will turn up lots of alternatives.
Choose what suits you best.


Cheers,
Bert
