The following PROJ.4 string is used: \code{+proj=eqdc +lat_1=27.11637320883929 +lat_2=53.050729042644335 +lon_0=-95.44921875}

|
In a ggplot2+ggalt context, you can just use variable name as the value for the \code{proj}
|
|
parameter to \code{ggalt::coord_proj()}. i.e. \code{coord_proj(us_eqdc_proj)}.
|
|
}

|

us <- usa_composite()

us <- sp::spTransform(us, sp::CRS(us_eqdc_proj))
|
|
us <- usa_composite(proj="eqdc")
|
|
counties <- counties_composite("eqdc")
