Hi, so I'm following the chapters from Geocomputation with R by Robin Lovelace, Jakub Nowosad, Jannes Muenchow
I working on the animated map from chapter 8
urb_anim = tm_shape(world) + tm_polygons() +
tm_shape(urban_agglomerations) + tm_dots(size = "population_millions") +
tm_facets(along = "year", free.coords = FALSE)
tmap_animation(urb_anim, filename = "urb_anim.gif", delay = 25)
Error message as follow
Error in CPL_transform(x, crs, aoi, pipeline, reverse) :
OGRCreateCoordinateTransformation() returned NULL: PROJ available?
In addition: Warning message:
In CPL_transform(x, crs, aoi, pipeline, reverse) :
GDAL Error 1: No PROJ.4 translation for source SRS, coordinate transformation initialization has failed.
I already install PROJ7 through the terminal, so does this error meant that my R still identify with older version PROJ? and how do I solve this?
