I'm solving the following problem: Create a variable (column) in the ?wf? dataframe named ?Zone? that takes value of ?tropic? if Latitude is less than or equal to 30, or ?non-tropic? for Latitude greater than 30. Show you Zone variable. Latitude is a column of my dataframe. I don't know the sintaxis and the process to create the column. [[alternative HTML version deleted]]
This list has a no-homework policy. I assume that your teaching material has examples that are sufficiently similar so that you should be able to modify them. -pd> On 8 Oct 2020, at 10:10 , Xavier Garcia via R-help <r-help at r-project.org> wrote: > > I'm solving the following problem: Create a variable (column) in the ?wf? > dataframe named ?Zone? that takes value of ?tropic? if Latitude is less > than or equal to 30, or ?non-tropic? for Latitude greater than 30.

Hello,
This question looks like a homework question. The posting guide syas that
"Basic statistics and classroom homework: R-help is not intended for
these."
I would take a look at
help('cut') # pay attention to argument labels
help('ifelse')
help('findInterval')
Hope this helps,
Rui Barradas
