How do I subset a Dataframe in R

Single and double square brackets in rSubset using brackets by omitting the rows and columns we don't want.Subset (res.gs, grepl ('^ [^0]', n_mutated_group1)) indexing also works.Subsetting operators interact differently with different vector types (e.g., atomic vectors, lists, factors, matrices, and data frames).The command head(financials$population, 10) would show the first 10 observations from column population from data frame financials:

Filter or subset the rows in r using dplyr.Subset a data frame with base r extract [] the most general way to subset a data frame by rows and/or columns is the base r extract [] function, indicated by matched square brackets instead of the usual matched parentheses.Getting a subset of a data structure problem.Add a comment 2 answers sorted by:However, i think the base function subset () may be the simplest.
