2 years ago Hi,
sorry for the delay but I am for offline winter break.
My code that always works is as follows:
pow<-readOGR(".", "powiaty") # map as object
pow<-spTransform(pow, CRS("+proj=longlat +datum=NAD83")) # change of projection
and try that map: https://www.sugarsync.com/pf/D1836703_09668593_6847342 (that is from my cloud)- that should work
best KK

Hello, I have faced strange problem when trying to change poviat projection (Chapter 2.1.). I run this code:
pow <- readOGR(dsn = 'C:/Users/mainUser/Desktop/spatial_book-master/powiaty', layer = 'powiaty') pow <- spTransform(pow, CRS('+proj=longlat +datum=NAD83'))
and the following error comes up:
Error in if (is.projected(obj)) { : missing value where TRUE/FALSE needed In addition: Warning message: In spTransform(xSP, CRSobj, ...) : NULL source CRS comment, falling back to PROJ string
I had some initial problems with powiaty files but downloaded updated .zip version from link given in Readme - and I read it to R. However, the error as above shows up.
