[...] 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. 3 3 Benin BEN - + NA 12 12 Congo COG - + NA 26 26 Mali MLI - + NA cu Philipp
