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.
Propagating lantana plants from cuttings is easy. Take cuttings of new growth in spring. Cut 4-inch tips from the stems and remove the lower leaves from the cutting, leaving only one or two leaves at the top. Prepare a small pot of seed starting mix or a half-and-half mixture of peat moss and perlite.
