MIL-HDBK-1823
"Nondestructive Evaluation System
Reliability Assessment"
If you already have R installed, skip this page and go
here.
Instructions for downloading R:
Since the mh1823 software is based on R,
the most powerful statistical and graphics engine available anywhere, you
must first visit the R website, http://www.r-project.org/, and download and install R. R is open-source (free)
and is supported by some of the most well known applied statisticians in the
world.
R is a language and
environment for statistical computing and graphics. It is a GNU project, similar to the award-winning S language and environment
which was developed at Bell Laboratories (formerly AT&T, now Lucent
Technologies) by John Chambers and colleagues.
Click
here to see examples of R's
extraordinary graphics capabilities. To return to the StatisticalEngineering
website, just X-out the new window.
How to install R
- Download the Windows binary files from the R website,
http://www.r-project.org/.
To do that click on CRAN (Comprehensive R Archive
Network) and choose a
mirror site in the US. From the CRAN page, click on Windows (95 and
later) then click on base to download the R base package.
Install R using the self-install feature of what you have downloaded.
- Open R by clicking on the desk-top icon.
- (As of 4 September, 2008) R has more than 1,517 free add-on packages for special
purposes. We need three of them. Within R, click on
"Packages, Install Packages ..." You will be asked to select a
local mirror site. Choose one near you.
- You will be presented with a new menu. Choose "RColorBrewer."
- Again click on "Packages, Install Packages ..." Since you have
already selected a mirror site you will go directly to the package menu.
Choose "rcom."
- Click on "Packages, Install Packages ..." and choose "
rscproxy."
- Finally, click on "Packages, Install Packages ..." again and choose
"RODBC."
- Close R, by clicking on the
 in the top right corner of the window.
We have some one-time loose ends to tie up:
- Right-click on the
 desktop icon and rename it to "mh1823
POD"
-
Open the mh1823
POD sub-folder and copy its
address. It will look something like this:
"C:\Documents and Settings\your name\My Documents\R-Projects\mh1823
POD" Highlight and copy this address.
-
Right-click on the newly renamed R desktop icon
and choose Properties, and paste the address in the Start in window.
-
You are almost finished. Again right-click on the
icon and choose Properties, then choose Change Icon... and click on
Browse. Navigate to your R-Projects folder, then your
mh1823 POD folder and click on
 (magnifying
glass mh1823.ico.)
Click OK.
You only have to install R and its ancillary
packages once. They will be there when you use mh1823 POD software
thereafter.
Note on permissions:
You may
find that your Windows default permissions won't allow
downloading *.zip files, so R installs easily, but
the add-on programs, like RColorBrewer, do not. You
may need to change (temporarily) your browser's security
settings or the overall security settings from the Control
Panel. You may also find some help here:
R-FAQ 2.19 The Internet download functions fail.
Note to Microsoft Vista users:
Vista's default security settings won't allow a program to
unzip and save a file, so R won't be able to install
the mh1823 POD
package (or any other package) . To avoid this
difficulty, open R by right-clicking on the icon
and choosing "Run as administrator." After
installing the three required packages and the mh1823 POD
package, R (with mh1823 POD)
can be
run thereafter without administrator privileges.
