[R] Panel regression in R

[Haibo Huang]

I am currently trying to replicate the results I got
from RATS for a panel regression. The codes in RATS
looks like this: 

* Final equation for Office Cap Rate Spread
* Regression, Panel Data
preg(effects=time, method=random) CapRate
# CapRate{1} RentCycle{1} VacancyChangeYTY
InflationYTY RealGDPyty 

Just wonder what R package also allow me to have the
options like (effects=time, method=random). Could
anyone share some thoughts with me? Any input will be
helpful. Thank you very much!

Best,
Ed.
