I am going to generate a Run Chart in R. I need a package and example to show me how to do this. I found the "qicharts" package but apparently is has a problem to install.
what kind pf Problem do you have while installing "qicharts"? Do you get an error? I am asking because it is working for me.
Nevertheless you might also want to have a lock at the "qcc"-Package. Here you can find something like a small introduction and here is the cran help to the package.
But I also think that the chance is high that you can plot your with "ggplot2" too.

Is there a R package for this? I´m looking for something similar to qrencoder but in 1D
For now, my walkaround solution is to use python-barcode through reticulate but I would like to use a R library.
library(reticulate)
barcode <- import("barcode")
name <- barcode$generate('EAN13', '7750243002455', output='barcode_svg')
My ultimate goal is to show barcodes of my products on a Shiny app
Have a look at the zintr package, which uses zint.
barcode_print(8675309, "barcode1.png")

I've been looking for a way to conduct group-based trajectory modeling in R with no avail. Something along the lines of what PROC TRAJ (http://www.andrew.cmu.edu/user/bjones/index.htm) accomplishes in SAS. Does anyone know of a similar package in R?
My outcome of interest (the model input) is categorical so i need something that can handle that.
The only package I've been able to find for this in R is crimCV. Here it is on Cran, and here is a working paper by the authors of the package on how it's done. I have not yet investigated this myself (and it seems like it hasn't been updated for years), but this page describes using it to fit a set of trajectories.

I know with using pack 'real', we can use embedded R in Prolog. But I met problems to use this pack. And I didn't find simple examples of using this pack.
Can somebody give a simple example of this pack?
e.g. Loading Prolog values on to R variables and then call R functions on these values (generate a plot by R function or whatever).
The syntax is the same as the SWISH version I think so just look here:
http://swish.swi-prolog.org/example/Rserve.swinb
and
http://swish.swi-prolog.org/example/Rdataframe.swinb

I'm studying about sparkR, and I know there are so many useful R package in CRAN. But it seems like R package can't be used in sparkR. I'm not sure about that.
Is it true??? If it's not, could you explain how import R package into sparkR?
I'm guessing that you may be referring to the includePackage command:
SparkR also allows easy use of existing R packages inside closures.
The includePackage command can be used to indicate packages that
should be loaded before every closure is executed on the cluster.

Is there a package for approximating a function using Chebychev Polynomials?
I was formerly using Matlab and there was a package called Compecon that can approximate a function using Chebychev Polynomials.
I am wondering if there is any packages similar for Julia.
Or is there any packages in C or fortran or Python that can do this?
Thanka a lot!
You might want to check out ApproxFun.jl, it may be relevant.
https://github.com/QuantEcon/CompEcon.jl and related https://github.com/QuantEcon/BasisMatrices.jl have the capacity I believe.
