Error in (function () : unused arguments (height = 8, width = 8)

Question

I am trying to plot my mean-variance plot using the mvabund package in R. The line of script that doesn't work is:

meanvar.plot(dat_mvabund, legend = TRUE)

I never had any problems with it but now I get an error message like this:

Error in (function () : unused arguments (height = 8, width = 8).

I have tried some online suggestions but nothing seems to work. I also re-installed R and R studio. I tried to run the command on an older database where I am sure it worked before but it is not working now.

My dat_mvabund looks like this:

Zotu17  Zotu22

8322    12  
20539   29  
6105    26  

This table was generated using the command: dat_mvabund <- mvabund(myData) where myData has: Zotus in columns and Sample names in rows.

I hope someone can help! Thank you!
