Xpose 4 is a ground-floor rewrite of Xpose 3.1. Chief amongst the enhancements
in the new version is the migration from S-PLUS to R, a free,
multi-platform statistical environment. We have also added direct access to Xpose
functions from the command line, and, through R, access to Xpose tools by
third-party applications.
R and required package installation
To install xpose you will need:
R version >=2.2.0. Download the latest version of R from www.r-project.org.
the gam package. Install the latest version from CRAN. Write at the R command
line (type ?install.packages in R for more details):
install.packages("gam")
Xpose 4 Installation
Install xpose in R using one of the following methods:
latest stable release -- From CRAN. Write at the R command line:
install.packages("xpose4")
Latest development version -- from Github. Note that the command below installs the "master"
(development) branch; if you want the release branch from Github add ref="release" to the
install_github() call. The install_github() approach requires that you build from source,
i.e. make and compilers must be installed on your system -- see the R FAQ for your operating system;
you may also need to install dependencies manually.
The Hmisc package is also recommended. to install, write at the R command line
(type ?install.packages in R for more details):
install.packages("Hmisc")
Running Xpose 4
Start R
To use the classic menu system, type at the R command prompt:
library(xpose4)
xpose4()
Each function is independently available from the command
line, once the Xpose library is loaded. For example, assuming your run is called
'run5.mod', you might do the following:
Import data
xpdb5 <- xpose.data(5)
Display goodness-of-fit plots
basic.gof(xpdb5)
More help is available in the online documentation, which can be found by
typing (for example) ?xpose at the R command line.
The Xpose 4 Bestiary
A more detailed description of Xpose with example plots and explanaitions for
most of the functions in the package is available in our Bestiarium:
