Hi everyone,

I constructed Networks wich are very large. I want to adapt them with cutoffs.

This is my code:

sum(network_day_0$wTO > 0.3, abs(wTO), na.rm = TRUE)

I get this Error:

Error in abs(wTO) : non-numeric argument to mathematical function

I tried this:

 sapply(network_day_0, class)    
 Node.1      Node.2         wTO 
"character" "character"   "numeric" 

And this:

 class(network_day_0$wTO)
[1] "numeric"

I'm not able to find the mistake. Can someone please help me?
