How did you change directory? Does dir() show that your
directory is the desktop? Presumably the desktop folder
is something like C:/Users/<someone>/Desktop. Sourcing
test.R from there should work. But the simplest way is

 source(file.choose())

and then navigate to where test.R is located.

Hi,

I saved the function in test.R file on Desktop. Then after starting R I
changed my directory to desktop.
and tried the command source("test.R") it gave me following error



Error in file(file, "r", encoding = encoding) : cannot open the connection
In addition: Warning message:
In file(file, "r", encoding = encoding) :
  cannot open file 'test.R': No such file or directory
