错误：`summarise()` 输入`wt` 的问题：geom_net 函数与新的 dplyr 版本不兼容

Question

I'm using geom_net function from geom_net R package.

Until few months ago I could use the geom_net function with non problems, but now I get the following error:

Error: Problem with `summarise()` input `wt`.
x could not find function "n"
ℹ Input `wt` is `n()`.
ℹ The error occured in group 1: 

My understanding of the error is that the summarise() function of dplyr package no longer uses the argument wt=n() as also specified in the dlyr R package recent update.

The problem is that geom_net uses a (now) old version of summarise() which is now incompatible with the new dplyr version.

Do you have any suggestion on how to solve the problem?

Answer 1

It looks like there's exactly one line in the geom_net source code that uses dplyr::summarise() with the wt argument:

edges <- dplyr::summarise(edges, wt = n())  

And the dplyr change log notes that wt is not replaced by anything, you can just omit it.

Use of wt = n() is now deprecated; now just omit the wt argument.

You should be able to just modify your local version of the geom_net package. Remove the wt argument from that single line.

(Note that this won't necessarily guarantee that geom_net runs without error, just that it resolves the specific issue you're asking about here.)
