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.
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.
Water Requirements: Low. Lantana horrida has a great show of flowers that last from spring till frost, the flowers a yellow color and and fade to an orange color along the outside edge and are great at attracting butterflies into the garden. Texas Lantana is drought tolerant, salt tolerant, deer tolerant, and has outstanding heat tolerance. Texas Lantana is native to the Rio Grande Plains and Southern Edwards Plateau in Texas. The leaves are smaller and rougher than Lantana camara, perhaps to help with the drier conditions of its native habitat.
