Error in gzfile(file, “wb”): cannot open the connection or compressed file

Question

I\'m trying to run two things: first, I\'m creating a PDF with 4x5, ending with dev.off(), and then trying to create a new graph. However, after starting the second plot, I get:

Answer 1

I have another instance of this error which seems to be new (or at least not listed here or here: apparently it's not OK to save a file with the name aux.RData. I guess it's a reserved filename.

x <- rnorm(9000)
save(x, file = "aux.RData")

Error in gzfile(file, "wb") : no se puede abrir la conexión
Also: Warning message:
In gzfile(file, "wb") :
  cannot open compressed file 'aux.RData', probable reason 'No such file or directory'

But when I change the filename saves with no problem:

save(x, file = "aux_file.RData")
