Mark, I've finally found an example that helps me to understand what
Henrique said. Here it is:
## sometimes requiring a logical 'subset' argument is a nuisance
nm <- rownames(state.x77)
start_with_M <- nm %in% grep("^M", nm, value=TRUE)
subset(state.x77, start_with_M, Illiteracy:Murder)
Coming from http://wiki.r-project.org/rwiki/doku.php?id=rdoc:base:subset
What I am not able to understand yet is Charles's proposal. Any insight
will be welcome!
Cheers,
Ricardo
