How to rotate igraph network plot?

问题

I'm trying to rotate the R package based igraph network plot. In the igraph guidebook not enough explanation how to use R code

tk_rotate(tkp.id, degree = NULL, rad = NULL) 

回答1:

For the R package igraph according to the documentation:

the tk_rotate rotates the figure, its parameter can be given either in degrees or in radians.

Of particular note is the argument tkp.id. Make sure you assign the tkplot window to this value so you can reference it as the tkp.id in the function.

tkp.id The id of the tkplot window to close/reshape/etc.

Here is a reproducible example that demonstrates it's use:

library(igraph)
#> 
#> Attaching package: 'igraph'
#> The following objects are masked from 'package:stats':
#> 
#>     decompose, spectrum
#> The following object is masked from 'package:base':
#> 
#>     union
g <- make_ring(10)
x <- tkplot(g)
tk_rotate(x, degree = NULL, rad = NULL)
