Hello,
I recently installed R on my new PowerBook G4 moving from the Windows
world. In that world, I was a fairly competent user. However there are
two
things about the Mac implementation that I can not figure out. Stefano
has
already tried to answer one of my questions. However, it did not work
or I
did not understand. Here are the questions:
1) When I try to change the directory and read in data using the
load("filename.Rda") command, I keep getting the following error
message:
load("filename.Rda")
Error: bad restore file magic number (file may be corrupted)-- no data loaded.
Rick, try to read the help files. If it is a simple txt file, then you should use read.table instead. There are a couple of good intros written by R-core members like: * An introduction to R * R Data Import/Export you can find both inside the doc folder of you installation of R or (better) on the www.r-project.org site in the "Manuals" section
All this is is a simple text file. I have tried changing the directory every which way, changing the extension etc but I can not read data in and I keep getting that error message. What do I need to do? This is very frustrating for such a simple operation. 2) The next question is how does one install a package that is not on the CRAN website? I downloaded the Simple package but do not know how to get it working. Dragging it in to the R folder does not seem to do it.
If packages does not contain C/Fortran code, then you can use any prebuilt version of it (either Windows or Unix) You cannot use packages as they are beacusa they need to be built. If you want to build packages on your own, have a look inside the R sources in the file INSTALL of the src/macintosh directory.
Thanks very much and thanks for the port to Mac OS X.
The "true" MacOSX version of R is the Darwin/R and not the Carbon one you are using. The Carbon version of R will be soon abandoned and fully replaced by the Darwin one. stefano
