In SAS I would do a data step with a MERGE statement. In R one way to perform these kind of set operations is to use the %in% operator like this. In the first case, you could use the R merge() function.ou just printed the desired data frame (where Ozone is not NA) to the screen. The last step (the only step you really need) is to âdeleteâ the rows by recreating the data frame: just reassign the data frame from the filtered rows.
Florida Native Lantana. The state of Florida has a native species of Lantana called Lantana depressa, or gold Lantana, which is classified as endangered. This rare plant is a creeping groundcover with yellow flower clusters and is native to the southern Florida county of Miami-Dade.
Texas Lantana laughs at hazards that can wipe out lesser plants; it resists drought, heat, deer, and salt. It doesnât even emerge from the ground until things really warm up. And then it springs from the roots so fast, it seems to magically appear full grown in a few warm weeks. Texas lantana (photo by Bill Lindemann). It thrives in the full summer sun and heat, requiring little water once established, and can be used as a shrubby ground cover in dry, poor soil.
