Data frame search and remove questions
...couple questions about removing rows from a data frame and
creating a new data frame with the removed values. I provided an
example data frame (d) below.
Questions:
1) How can I search for "-999.000" and remove the entire row from data
frame "d"? (all -999 values will be in sd_diff)
2) Can I create a new data frame "d.new" that only contains the removed
rows?
3) How can I remove the last two rows from a data frame. (I used append
command to add two values to the end of the data)
