Problem loading .r file

I think your immediate problem is that you are asking this particular question in the wrong forum. It appears that you are following instructions (in a book? a class?) and you need to direct your questions to the author of those instructions.

You may find it helpful to know:

a) The load function does not work on R source code files (.R) but on R data files (.rda or .RData).
b) You can (and most likely should) open .R files in the text editor of your choice and start reading.
c) There is a Posting Guide for this mailing list mentioned at the bottom of this and every other email from this list.
d) There is a well-written Introduction to R pdf document supplied with the R software.

Hello all,

I was trying to load a .r file using source() and load() functions.
Although I could be able to load the codes (mainly few user defined
functions) written in that .r. file correctly, however getting
following error:

source("D:/Book Code.r")

Error in sys.call(sys.parent()) : node stack overflow

load("D:/Book Code.r")

Error: bad restore file magic number (file may be corrupted) -- no data
loaded
In addition: Warning message:
file ?NG Book Code.r? has magic number 'Pos_T'
  Use of save versions prior to 2 is deprecated

What is the possible problem?

Thanks and regards,
