[R] how can I delete rows?
Hello, I am very new in R so I am so sorry for this question. I have the Barro-Lee data set which contains 98 countries and I want to run the regressions only for the Latin America countries, so what do you recomend? How can I delete all the other countries or how can I select the countries of Lat.

Assuming the data is stored in a data frame called bl you could do
something like this:
First you generate a list of all countries you are interested in - e.g.
set = c('Benin', 'Congo', 'Mali')
And then you subset the data frame with it
bl[bl$COUNTRY %in% set, ]
SHCODE COUNTRY NAME WBCTRY X.1. X.2.

12 12 Congo COG -+ NA
