[R] Error in leaps.

[John Kane]

Hi Cindy,Welcome to R-help.
Have  a look at the posting guidelines and their suggestion about a minimal example. What we  need to help you is some sample data and a "minimal" amount of code that illustrates your problem. Someone may be able to guess the problem from your errror message but I'd not bet on it.

Have a look at http://adv-r.had.co.nz/Reproducibility.html for some excellent suggestions on how to do this. And please supply the data using the dput() command. It provides an exact copy of the data on your computer so we know we are working with exactly the same data you are.

 Dear All,

I am trying to use the model, Program Evaluation in order to determine the
economic impact of a policy change. While trying to run my own data on
RStudio, using the codes from the paper "An R Package for the Panel
Approach Method for Program Evaluation: Pampe" by Ainhoa Vega-Bayo, I keep
encountering an error that reads:

Error in leaps.setup(x, y, wt = weights, nbest = nbest, nvmax = nvmax,  :
  y and x different lengths

To be honest, I am very new to R so I am not familiar with how it works and
what every thing means, so its been quite a challenge for me to overcome
this error. The packages that I have installed are "Formula", "plm",
"leaps" and "pampe".

If anyone could provide some help and advice on how I could overcome this
error, it would be greatly appreciated.

I am happy to provide more information if needed.

Regards,
Cindy
