Error in str.igraph for code 2.4 - Can't proceed using N

> N <<< 2.4 str(g) Error in adjacent_vertices(x, i, mode = if (directed) "out" else "all") : At iterators.c:759 : Cannot create iterator, invalid vertex id, Invalid vertex id

Searching for this error turns up this StackOverflow post - https://stackoverflow.com/questions/46137227/r-str-gives-unusual-return-using-igraph

It seems that as of igraph 1.1.1 that str() is defunct and you need to use print_all(g) instead of str(g), which gives the correct output for 2.4.

However, there doesn't seem to be a way to skip over a code section within a chapter using N, so the rest of the code needs to be manually entered.

I would recommend updating the code for 2.4 and also implementing a function for skipping a code section or jumping directly to a code section.

Thanks!

Installing from Cran is already available

Hi, I was wondering if the package documentation would be updated. Is still showing to install from github because Cran download is not yet released.

install.packages("devtools")
library(devtools)
install_github("kolaczyk/sand/sand")

I believe the Cran package is available to download with the regular package installing code.

install.packages("sand") 

By the way thanks for the excellent book!

Cannot install "sand" in current R version

install.packages("sand")

error when using str()

Running the chapter 2 code block

g <- graph.formula(1-2, 1-3, 2-3, 2-4, 3-5, 4-5, 4-6, 4-7, 5-6, 6-7)

str(g)

I get the following error

Error in adjacent_vertices(x, i, mode = if (directed) "out" else "all") : At iterators.c:759 : Cannot create iterator, invalid vertex id, Invalid vertex id

Let me know if you need more information, not sure what is standard to submit with an issue.

Thanks!

mixer package unavailable in CRAN

The mixer package is unavailable at the repository. Does anybody have a work around to execute code chunks from Chapter 6?

error message using R 4.3.1

Third command line in Chapter 1 gives the following:

install_sand_packages()
Error: With R version 3.5 or greater, install Bioconductor packages using BiocManager; see https://bioconductor.org/install

I have installed latest version of BiocManager but don't know which Bioconductor packages are needed to run the rest of the chapters although those that depend on igraph work perfectly fine.

V(fblog.c) crashes after fblog.c <- contract.vertices(fblog, party.nums) in CHUNK 14 of Chapter3.R

Hi, Kolaczyk,

First, many thanks for this nice book! Below is the issue:

In CHUNK 14 of Chapter3.R
I tried to run V(fblog.c) immediately after fblog.c <- contract.vertices(fblog, party.nums), then it crashed
I also tried summary(fblog.c), it also crashed
The system mentioned that it's igraph.so that crashes
Although the crash is not in your code, but it's related.
Do you know how to fix that?

Below is my R version:
platform x86_64-pc-linux-gnu
arch x86_64
os linux-gnu
system x86_64, linux-gnu
status beta
