Warning message in setwd - R

Question

I have a workflow with three different operating systems and I use the switch function in R to change my working directory between them.

It works fine in Windows and macOS, but in Linux, returns a warning message and I don't know why.

I'm using Elementary OS 5.1 Hera, and that's the code:

switch (Sys.info()["sysname"],
        Linux = setwd("~/Documentos/GitHub/Economic Activity Monitor"),
        Darwin = setwd("~/Documents/GitHub/Economic Activity Monitor"),
        Windows = setwd("~/GitHub/Economic Activity Monitor")
)

The warning message:

#Warning message:
#In normalizePath(dirname(f)) :
#  path[1]="NA": No such file or directory

It changes the working directory, but I would like to understand why is returning that message only on Linux.
