Following this documentation, when trying to estimate the volume of a 3-dimensional cube with GenCube() function I get this error:

Error in GenCube(3, "H") : could not find function "GenCube"

The result of running help("GenCube") :

No documentation for ‘GenCube’ in specified packages and libraries:
you could try ‘??GenCube’

When trying to install the package or create it's documentation, a library specific error is generating. To replicate this within RStudio, one can execute the following two commands:

Rcpp::compileAttributes()
roxygen2::roxygenize(roclets="rd")

want to run different sampling algorithms in a 100-dimensional cube. I get the output for "RDHR" and "CDHR" but for the "john" (john walk) I get the following error:

Error: Unknown walk type!

My code is as below and I follow page 24 of Rvolesti documentation pdf. on sample_points() function.

library(ggplot2)
library(volesti)
for (step in c(1,20,100,150)){
  for (walk in c("RDHR", "CDHR", "john")){
    P <- gen_cube(3, 'H')
    points1 <- sample_points(P, n=1000, random_walk = list("walk"=walk, "walk_length"= step))
    g<-plot(ggplot(data.frame( x=points1[1,], y=points1[2,] )) +
geom_point( aes(x=x, y=y, color=walk)) + coord_fixed(xlim = c(-1,1),
ylim = c(-1,1)) + ggtitle(sprintf("walk length=%s", step, walk)))
Sys.sleep(10)
  }
}

This issue deals with the upgrade to a newer version of volesti. This upgrade should be done by following the steps bellow.

• Update the relevant "include" branch in volesti repository
• Update the submodule
• Fix possible issues
• Write tests (wherever are missing)
• Write documentation (wherever is missing)

The currect README should be updated (at least) on the following points:

• Update submodule path
• There should not be needed to cd src/include when you update the submodule
• Documentation links and credits are outdated
• There is a confusion when referring to volesti and Rvolesti

I get the warning:

Warning message:
object ‘CsparseMatrix’ is not exported by 'namespace:Matrix' 

when running the followings in the R terminal:

devtools::test()

devtools::run_examples()

I run the above commands in the /test folder of the project.

We have to write CI yaml scripts that test the R package against various platforms and R versions.

The scripts from volesti package can be used.
