Run: liuyu :~ /Mytars/epd_free-7.3-2-rh5-x86_64/bin/workbench $../python2.7 A. py

2. installation to participate in http://blog.sina.com.cn/s/blog_61f013b80100yhef.html, I installed the license is R-2.15.2

2 installation successful

 

3. The installed version is gsl-1.9, the installation location is liuyu :~ /Gsl4. after installing the above four open source libraries, my. bashrc content is as follows:

Export Path = $ path:/home/liuyu/mytars/epd_free-7.3-2-rh5-x86_64/bin
Export Path = $ path:/home/liuyu/mytars/R-2.15.2/bin
Export r_home =/home/liuyu/mytars/R-2.15.2/bin/R
Export r_libs =/search/liuyu/mytar S/R-2.15.2/Library
Export LD_LIBRARY_PATH =$ {r_home}/lib :$ {LD_LIBRARY_PATH}
Export LD_LIBRARY_PATH =/usr/local/lib: $ {LD_LIBRARY_PATH}
Export LD_LIBRARY_PATH =/home/liuyu/GSL/lib :$ {LD_LIBRARY_PATH}

5. Install software by source code

Tar-xzvf source.tar.gz

CD Source

./Configure -- prefix = dir // specify the installation directory

Make

Make install

Uninstall make uninstall

6.ProgramCall the GSL Library (use automake for compilation)

Install gnuplot 1. download the wxGTK-2.8.12-i486-1alien.tgz, unzip it and copy the libwx_gtk2u_richtext-2.8.so.0.8.0 to/usr/local/lib (the reason for putting it here is because/etc/lD. so. conf specifies this directory as the functional directory of the Dynamic Link Library) 2. then enter the source code and install my gnuplotsource code with the rootid as gnuplot-4.6.rc1.tar.gz 3. then configure path export Path = $ path: gnuplot installation directory 4 in bashrc. call the file name plot. GP contains the following content: 1 plot sin (X)
2 Set grid
3 set xlabel "X"
4 set ylabel "Y"
5 set terminal PNG
6 set output "plot.png"
7 replotgnuplot plog.gpwill download plot.png in the previous example

F = scan (file = "f3.txt ");
Quantile (F, 0.01 );
# PNG (file = "myplot2.png", BG = "Transparent ");
# Boxplot (f );
Fivenum (f );
Summary (f );
