Downloading `VGAM`

VGAM is now on CRAN so you can get it from there. Alternatively, you can download it below.

For Windows and Linux/Unix, the easiest way to install VGAM is to run R, and type

install.packages("VGAM", repos = "http://www.stat.auckland.ac.nz/~yee")

To obtain a local library in Linux/Unix, type something such as

install.packages("VGAM", repos = "http://www.stat.auckland.ac.nz/~yee",
                 lib = "/myhome/directory/myRlibs")

Then typing

library(VGAM)

will load the package in. However, in Linux/Unix, first have a file called .Renviron in your home directory with the line

R_LIBS=/myhome/directory/myRlibs

in it. Here, /myhome/directory/ specifies your home directory, e.g, something like /home/yee/.

Alternatively, you can manually download VGAM...

VGAM is available in four flavours:

(A) R 2.14.x library for Linux/UNIX

[ 1.8 MB tar GNU Zipped (.tar.gz) ]

(B) R 2.14.x library for Windows

[ 4.0 MB zip file (.zip) ]

(C) MacOS X binary

[ Available on CRAN ]

(D) S-PLUS 6.x library for Linux/UNIX (very very old; not advisable!)

[ 510K Compressed (.Z) | 316K GNU Zipped (.gz) ]
Actually, this isn't really in library form.

Older versions, what's new and prerelease version

Version 0.8-4 requires R 2.11.1 or up. It no longer has Fortran 90 code so there should be no more compiler problems!

So what's new in the latest R version of VGAM? click here.

Some bugs are found and fixed up immediately. Here is a link to the latest (prerelease) version of VGAM.

General installation instructions

For R, if you fetch the Linux/Unix GNU Zipped form, type something like
```
    R CMD INSTALL -l ./myRlibs VGAM_0.8-4.tar.gz 
```
to obtain a local library of VGAM.
For R, if you fetch the Windows zipped form, click on "Packages" and then "Install package(s) from local zip files..." and then choose the VGAM .zip file. Then click on "Packages", "Load package..." and then choose VGAM.
For Splus (not recommended at all), if you fetch the Linux/Unix compressed forms, type something like
```
    uncompress VGAMS6.tar.Z
    tar xvf VGAMS6.tar
```
A directory called called VGAM will be created in the current directory. See the Installation file there for further instructions.
