Hi, I am using R-1.5.1 on windows 2000. I encountered a problem when I tried to load a ascii .RData file whose first line is "RDA2". The error message is "restore file may be from a newer version of R -- no data loaded". I noticed that the error comes from magic comparison when load file. The magic comparision of the first five characters in the ascii file and the "RDA2\n" is always fail, and then comparison of "RD" is successful. How can I solve the issue if I'd not like to recompile the source code? Looking forward to hearing from you. Thanks.

Load Ascii file in R

How did you get such a file? My guess is that you transferred the file from some other machine and mangled the line endings en route. As the following shows,
save(ls, file="foo", ascii=T)
load("foo")
it does work, and the file is written with LF and not CRLF line endings. If I convert that file to CRLF line endings I get the error you report. The solution seems to be to either convert the file to LF in a good editor, or to track down where it is getting corrupted.

How did you manage to find out what the binary code was doing without building a debug version?
