filename of source file
Yes, source refers to the use of the source() function. Suppose I invoke
a file like so:
source("/path/name/filename.r")
I want to insert a command in filename.r like so:
fullpath <- magic_command()
such that fullpath is now "/path/name/filename.r"
In other words, I want filename.r to be able to figure out where it is,
regardless of where I put it, so that it can save all its output in the
same directory.

Dave, You may like to give an example usage since I'm not 100% sure what you wish to achieve. Does "current source" refer to the source() command, to read.table(), or to something else? You may like to create a variable save.dir in your .Rprofile or in your working session that points to the folder you want everything saved in. Regards, Andrew C.

Hi Is there a command which will return the complete pathname of the file from which the current source is being read? I want something which can be inserted into any .r file and it will be able to ascertain exactly where it is, so that it can save data to the same directory, no matter where it is, regardless of what the current working directory is.
