I need parallel coordinates plot with interactivity in shiny. This is the plot that I want and this is a solution of producing rCharts in shiny.
If you need interactivity, have a look at either ggvis or D3.js. ggvis is an R based solution, and D3.js uses Javascript. The first is still quite experimental, D3 is already very mature and can produce very nice interactive graphs (rendered client-side). This would whoever mean you need to learn JavaScript.

I have a task a bit complicated for my knowledge in R. I need to reproduce this graphic of the figure in R, I performed several searches and could not find anything. The main thing is to be able to reproduce the graphic (it doesn't have to be identical), subtitles are not so important. Any ideas on how to do it or just using another program? Thanks!!
Check also the facet_share() function of the ggpol package, very handy for population pyramids/comparisons

By using Sci-lab I need to draw triangle cicrle and rectangular (separately, of course). the most difficult for me is triangle, I have no idea how to plot them
Plotting is rather trivial. See the plot command reference.
There are shorter ways, but for easiest understanding just plot the three sides as three lines.
For instance if you have a triangle with the corner coordinates at (x,y) = [0,0],[5,10],[10,0]. Plot three lines between these points.
plot([0,5],[0,10])
plot([5,10],[10,0])
plot([0,10],[0,0])

I am using knitr and Latex to write an intro into and overview of R. How can I get a box around R code chunks and R output in Latex? I can get them when using R Markdown and knitr to generate HTML. The Sweave way to frame chunks with a box does not work with knitr.
Thanks and regards,
Andreas

This is a borderline question for Stackoverflow, I know, but I am looking for a package. If I can't get an answer here I will transfer to https://stats.stackexchange.com/. I am looking for a R package or a method to create a phase diagram. This means I have e.g. two variables, like air pressure and temperature, and a binary variable (to make it easier) indicating if the substance is liquid or frozen. Below you find a typical example of a phase diagram. I need to estimate the transition borders or something however just in a case with two groups. Every hint is appreciated.
I think about the closet you will get is function diagram in package CHNOSZ. There's a lot to read about in this package and it has some nice vignettes. But, it seems to calculate phase diagrams from first principles or theory. Perhaps if you look at the code for diagram you can figure out a fairly easy way to use your empirical data.

I'm a student just learning how to use R and thus far I've made a bit of progress. I'm snagging at a question which asks: For what values of i does Y equal 3?
the data set: c(3,5,2,3,5,4,4,2,3,5)
If I understand your question correctly, you want the index, i inside the data set (in this case, a vector) Y such that Y[i]=3?
Then you just need to use the which function. For more information, make sure you try reading the help files, which you can invoke using the command ?which or help(which)
Now, some code:
# Your data
Y <- c(3,5,2,3,5,4,4,2,3,5)
# Find the index where Y is equal to 3
which(Y==3, arr.ind=TRUE)
And welcome to SO. This is a pretty common question for beginners, so next time, make sure you Google or search around for a solution to elementary problems such as these. Have a good day.
