3 years ago Nevermind on this issue. Although I was not able to figure it out, I conveniently received a new computer yesterday and was able to do a fresh install of R and Rstudio and a bunch of packages. Everything's working on the new computer so I'm good.
I recently upgraded to version 1.4-5 because i was several versions behind. Unfortunately, I'm no longer able to define projections using code like the first line below. I know I'm not the only one experiencing this issue because I found the workaround that is my 2nd line of code below from the answer provided in this link to a post made back in February. https://gis.stackexchange.com/questions/387072/r-spcrs-returns-na
txspsc<-sp::CRS("+init=epsg:2278") gives "Error in sp::CRS("+init=epsg:2278") : NA" txspsc2<-sp::CRS(sf::st_crs(2278)[[2]]) works
The sf workaround allows me to export sp files to shp (yielding a prj) for use in ESRI and other systems, but I'm finding that a lot of my tools (homegrown and from CRAN packages) that use sp objects are no working because they think the CRS is empty for some reason. For example, elevatr::get_elev_raster() yields "error in evaluating the argument 'CRSobj' in selecting a method for function 'spTransform': NA".
Are you able to replicate this behavior and, if so, would it be coming from sp, rgdal, or something else? I reinstalled rgdal and my session info is below. Thanks so much.
