[R] Choosing subset of data.frame

Dear R Forum I have a data frame as beta_results = data.frame(instrument = c("ABC", "DEF", "JKL",  "LMN", "PQR", "STU", "UVW", "XYZ"), beta_values = c(1.27, -0.22, 0.529, 0.011, 2.31, -1.08, -2.7, 0.42)) > beta_results   instrument beta_values 1    ABC   1.270 2    DEF  -0.220
