Unknown Walk Type

[FareheSoheil]

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)
  }
}

Sorry, I cannot reproduce it. I can run

P = gen_cube(3, 'H')
points = sample_points(P, n = 100, random_walk = list("walk" = "john", "walk_length" = 5))

successfully locally. Are you building Rvolesti from develop branch?

Your code produces the same error on my device.
Yes, I cloned and built all packages from develop branch.

Could you provide more information about your platform/compiler used and also the exact steps you followed?
Can you run the tests and the examples successfully?
