Deg.to.merc package?

[Alexandra McInturf]

Hey all -

This should be a simple question, but does anyone know the package that is required for the function used to convert deg to mercator units in R?

Thanks!

Hi Alex,

If you can get your data into a spatial dataframe you can use: rgdal::spTransform to re-project most any data, if you know your current projection/units.

However, a newish package called "sf" makes working with spatial data really easy, and I'd recommend using it. It pulls the spatial data in, but retains a "tidy" dataframe you can work with much more easily. Basic functions you may use within the package:

• st_read() to get a shape/raster/spatial data in
  
• st_set_crs() set a coordinate reference system if it doesn't have one
• st_transform() transform your CRS to something new
• st_crs() double check it worked

Good luck!
