If I try to load data from an alias file made using Cmd+Ctrl+A in finder
for MacOSX, I get an error. Symbolic links are working well but
sometimes, it is easier to use finder rather than terminal.
Has someone a solution to help R to read the original aliased file ?
Thanks
Here is a reproducible example:
A <- 10
save(A, file="A.Rdata")
rm(A)
# Make hard link
system(paste("ln A.Rdata B.Rdata"))
load(file="B.Rdata")
# It works
print(A)
rm(A)
# Make symbolic link
system(paste("ln -s A.Rdata C.Rdata"))
load(file="C.Rdata")
# It works
print(A)
rm(A)
# Make an alias of the A.Rdata file in finder using Cmd+Ctrl+A; the name
of the new file is "A.Rdata alias"
load(file="A.Rdata alias")
It failed with this error:
Error in load(file = "A.Rdata alias") :
?? mauvais num??ro magique de restauration de fichier (le fichier est
peut ??tre corrompu) -- aucune donn??e charg??e
De plus : Warning message:
