7. Xpose is now installed in R's library subfolder, with all its dependencies intact. You may load it
using
> library(xpose4)
and start the classical menu system, if you are nostalgic, using

Installation from the command line (Linux or Windows)
1. Download the latest version of R from www.r-project.org and install it.
2. Download the latest version of Xpose for your operating system
3. Start R. At the R command line enter:
> install.packages("Hmisc")
> install.packages("gam")
and the Hmisc and gam packages will be downloaded and installed from the mirror you select.

3. Alternatively, you can download the packages for Hmisc, gam and akima from:
http://cran.r-project.org/web/packages/Hmisc/index.html
http://cran.r-project.org/web/packages/gam/index.htm
http://cran.r-project.org/web/packages/akima/index.html
Start R. Enter (in Windows, for example)
> install.packages(c("c:/temp/Hmisc_3.0-12.zip", "c:/temp/gam_0.97.zip", "c:/temp/gam_0.97.zip"),
repos=NULL)
assuming you put your downloaded files in the directory "C:/temp".
Type '?install.packages' at the R command line for more details.
4. Install Xpose 4. At the R command line type:
> install.packages("c:/temp/xpose4data_4.3.0.zip", repos=NULL)
> install.packages("c:/temp/xpose4generic_4.3.0.zip", repos=NULL)
> install.packages("c:/temp/xpose4specific_4.3.0.zip", repos=NULL)
> install.packages("c:/temp/xpose4classic_4.3.0.zip", repos=NULL)
> install.packages("c:/temp/xpose4_4.3.0.zip", repos=NULL)
if you are using Windows (change to the correct version number!), or
> install.packages("c:/temp/xpose4data_4.3.0.tar.gz", repos=NULL)
> install.packages("c:/temp/xpose4generic_4.3.0.tar.gz", repos=NULL)
> install.packages("c:/temp/xpose4specific_4.3.0.tar.gz", repos=NULL)
> install.packages("c:/temp/xpose4classic_4.3.0.tar.gz", repos=NULL)
> install.packages("c:/temp/xpose4_4.3.0.tar.gz", repos=NULL)
if you are using Linux. Note that this assumes that you have stored
your downloaded files in "C:temp" or "/tmp/" and that the version number is 4.3.0.
Substitute as needed.
NOTE: for windows, ensure you have downloaded the BINARY distribution (.zip).

4. 5. Xpose is now installed in R's library subfolder, with all its dependencies intact. You may
load it using
> library(xpose4)
and start the classical menu system, if you are nostalgic, using
> xpose4()
Building Xpose 4 from source (Linux or Windows)
it may be desirable to compile Xpose yourself if you need to customize Xpose, or if you wish to
work on a port to a different operating system, or another software host such as S-PLUS.
For Windows users, you will need to download the source distribution
(e.g. xpose4_4.0.1_src.zip) from the website. In addition you will
need to download some package building toolsets from the web. We
direct you to this rather useful tutorial on building R packages under
Windows:
http://www.maths.bris.ac.uk/~maman/computerstuff/Rhelp/Rpackages.html
This description is a bit outdated but useful as well:
http://faculty.chicagogsb.edu/peter.rossi/research/bayes%20book/bayesm/Making%20R%20Pac
kages%20Under%20Windows.pdf
In addition the R help manuals give lots of information:
http://cran.r-project.org/doc/manuals/R-admin.html#The-Windows-toolset
http://cran.r-project.org/doc/manuals/R-exts.html
Your task under Linux should be much simpler. All the tools you need ought
to be available already in almost all distributions. Simply follow the
instructions above for istallation from the command line. The *.tar.gz release version of xpose 4
is a compressed source distribution that can be built using the
command above. For more help on building R packages see:
