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]]

Hi everyone, I wonder if anyone knows the reason why the outputs of the same reprojection in r and arcgis are different?. The magnitude of the change can be up to 40 km in the poles. Basically, I have a database of points equally separated by one degree over the globe. In ARCGIS, I am projecting the data in GCS-WGS-1984 and then reprojected it to Berhmann to ensure equal area

Hi, everyone, I haven't found anything similar in the forum, so here's my problem (I'm no expert in R nor statistics): I have a data set of 59.000 cases with 9 variables each (fractional coverage of 9 different plant types, such as deciduous broad-leaved temperate trees or evergreen tropical trees etc.), which was generated by a vegetation model. In order to evaluate the quality of the vegetation model's output, I want to compare it to a land-cover data set which has 23 different land-cover types (such as needle leaved evergreen forest, dense broad-leaved forest, barren, etc.). A s...
