How to translate from stata to R

In stata, I regressed OLS (pannel data) by the following code:
reg lrgdpchlight lrgdpchWDI t* country*, cluster(iso_n) (iso_n =country)

t* is year fixed effect,
country* is country fixed effect.
I used cluster (by country) . However, I do not know how to do the same thing in R?

In R --> lm( y~x + factor(year) + factor(country) ) ----> how about include cluster((country) in R ?


To help us help you, could you please prepare a reproducible example (reprex) illustrating your issue? Please have a look at this guide, to see how to create one:

r package plm estimates twoway fixed effects models and the sandwich package may help you with the variance/covariance matrix of the estimators.

I would suggest reading the Journal of Statistical Software piece on plm.
