Hi everybody, Does anyone know how to delete certain rows (satisfying a particular condition) of a data frame in R? Thanks u, Shubha [[alternative HTML version deleted]]
Try ?subset.
See the following example.
nm <- rownames(state.x77)
start_with_M <- nm %in% grep("^M", nm, value=TRUE)
subset(state.x77, start_with_M, Illiteracy:Murder)
