I think the labels for North and East are flipped in the trajectory line plots. Swissgrid coordinates starting with 1 (1'xxx'xxx) are always the north coordinates while 2'xxx'xxx are the east coordinates.

Recognizing this, I tried to flip my plot, but could not figure out how to do this with coord_sf. Any ideas?

I'd say you can just rename the colums after reading in the data. Worked for me.

caro <- read_delim("data/caro60.csv", ",")

caro %>%  dplyr::rename(N = E, E = N) #renaming because N and E were flipped

caro <- st_as_sf(caro, coords = c("N", "E"), crs = 2056, remove = F)

Hey @thereallinusrg: Thanks for pointing out the error! You are of course right, the axes were mixed up. I resolved this (https://github.com/ComputationalMovementAnalysis/FS21/commit/324831a79f37b1288a1038712e2f5f7a6916309d) and rebuilt the book (https://github.com/ComputationalMovementAnalysis/FS21/commit/eac7471879ff46bbd97f72c973736014ba6cb3fc). So if you download the dataset caro60.csv again, the issue should be resolved.

That being said: I am glad none of you suggested simply changing the axes names in the original csv, which would not be a good idea (since it's not reproducible). @wildhtob's solution is what I would have suggested as well.
