warning on some graphs

[latot]

Hi, I was running some tests in a lib, and I found the next warning which seems to be new:

Warning message:
In cbind(from, to) :
  number of rows of result is not a multiple of vector length (arg 1)

I does not know how/why happens, here a reprex:

library(wrapr)

sfnet2cppRouting <- function(
    network,
    weight) {
  cppRouting_graph <- cppRouting::makegraph(
    network %.>%
      sfnetworks::activate(., "edges") %.>%
      sf::st_as_sf(.) %.>%
      sf::st_drop_geometry(.) %.>%
      as.data.frame(.) %.>%
      dplyr::transmute(., .data$from, .data$to, cost = .data[[weight]]),
    directed = igraph::is_directed(network)
  )
  # }
  original_nodes <- network %.>%
    sfnetworks::activate(., "nodes") %.>%
    sf::st_as_sf(.)
  if (nrow(original_nodes) != cppRouting_graph$nbnode) {
    stop("The net was simplified by cppRouting, the nodes assignation can be broken.")
  }
  cppRouting_graph
}

network <- local({
  file <- "net_flat_5_sfnet-0.6.3.gpkg"

  sfnetworks::sfnetwork(
    sf::st_read(file, layer = "nodes", quiet = TRUE),
    sf::st_read(file, layer = "edges", quiet = TRUE),
    directed = FALSE
  )
})


ret <- cppRouting::get_multi_paths(
  Graph = sfnet2cppRouting(network, "weight"),
  from = c(1, 2, 3),
  to = c(5, 6, 7, 8)
)
Warning message:
In cbind(from, to) :
  number of rows of result is not a multiple of vector length (arg 1)

Network used:
net_flat_5_sfnet-0.6.3.zip

Thx!

Yes, my bad. It occurs when get_multi_paths function is called, more precisely when we check if there are NAs in from and to.
It will be fixed.
