Graphics, Figures & Tables ⇒ Descriptive Statistics

[jafarHH]

Hello guys i need help with Descriptive Statistics,
i don't know how to make these in latex so i need help.
can anybody explain for me how i do it

I'm not sure if I understand you right. I found some explanations but I can't figure out what you are after [1]. So, please explain exactly what you want to do and where the problems occur.

There is no real problem,
it's just that i can't find any tutorial or guide that shows how you make descriptive statistics in Latex i mean the commands for it, im pretty new and i need it for an exercise i got from school to do over summer.

I'm afraid that I still can't follow you. Commands for what? Some kind of operations? As far as I understand that, it is only about tables and figures which serve for clear depiction of data. If possible, give a visual example of what you want to achieve.

i want to be able to do something like this.
and BTW how do you insert images?

Such pie charts can be done with package like pgf/tikZ or PSTricks [1,2]. For a 3D representation it will get a little bit more complicated.

External image files are inserted by the graphicx package.

Thx that made it a little bit more clear for me,
one last question how do you do plots,

my dad who is a teacher in the university is using something called matlab but im just in college so i wonder if you could do it in latex.
thanks in advance,

hope i don't get too annoying.

[localghost]

Plots can be done with pgfplots or pst-plot, which are based on the packages I mentioned in my last reply.

You could also use R to produce statistical graphics, including 3D pie charts (though pie charts are usually frowned upon in statistics). R can export to LaTeX formats, including TikZ.

For example, to make a 3D pie chart in R exported to TikZ format, you need the tikzDevice and plotrix packages installed in R, then do this in R:

Code: Select all

library(plotrix)
require(tikzDevice)
tikz('pie3D.tex',standAlone=FALSE,width=5,height=5)
counts <- c(20,29,13,22,16)
types <- c("A","B","C","D","E")
lbls <- paste(types,counts,sep=": ")
lbls <- paste(lbls,"\\%",sep="")
pie3D(counts,labels=lbls,main="Answers for $\\int_1^2 \\frac{dx}{x}$")
dev.off()

That will create a pie3D.tex file which you can then use in LaTeX like this:

Code: Select all

\documentclass{article}
\usepackage{tikz}
\begin{document}
Here is a pie chart created by R:
\begin{center}
   \input{pie3D}
\end{center}
\end{document}

The result will look like this:

Notice that you can put LaTeX symbols in the chart. You can also control label positioning and lots of other settings.
