"R session aborted" when calling plos_ssa

[pilopilota]

Dears, I'd like to upgrade GillespieSSA to GillespieSSA2, but something goes wrong.

When I run the following script, reaching plot_ssa causes R session to abort:

library(GillespieSSA2)
sim_name <- "Decaying-Dimerizing Reaction Set"
final_time <- 10
params <- c(c1 = 1.0, c2 = 0.002, c3 = 0.5, c4 = 0.04)
initial_state <- c(s1 = 10000, s2 = 0, s3 = 0)

reactions <- list(
  reaction("c1 * s1",        c(s1 = -1)),
  reaction("c2 * s1 * s1",   c(s1 = -2, s2 = +1)),
  reaction("c3 * s2",        c(s1 = +2, s2 = -1)),
  reaction("c4 * s2",        c(s2 = -1, s3 = +1))
)

set.seed(1)
out <- ssa(
  initial_state = initial_state,
  reactions = reactions,
  params = params,
  final_time = final_time,
  method = ssa_exact(),
  sim_name = sim_name
)

plot_ssa(out)

The same happens when running ?plot_ssa or ?ssa.

This is the output of R.version

If it can be helpful, I'll be happy to give further information. Thanks for your work! Paolo

The same happens now that I updated R to 4.1.2

Hi Paolo!

Does the problem still persist? Have you tried reinstalling GillespieSSA2 from source?

At the moment, I can't reproduce it from my end. On the CRAN package checks, everything seems to be ok for Mac OS systems. Also the GitHub Actions Mac OS X runner seems to be working fine.

What kind of a computer do you have?
