Randomly got an error message in the R console: `Error in exists(mname) : first argument has length > 1`

I randomly got an error message in the R console: Error in exists(mname) : first argument has length > 1. After searching the codebase, I found this error was caused by nvim.getmethod() function. Changing exists(mname) to any(exists(mname)) should do the trick. But I am not familiar with nvimcom codebase and am not sure that mname should already be a single vector in the first place, and there are other places causing it to be a vector of length > 1.

           nvim.getmethod <- function(fname, objclass) { 
        
               mname <- paste0(fname, ".", objclass) 
        
               if (exists(mname) && is.function(get(mname))) 
        
                   return(mname) 
        
               return(fname) 
        
           }

I found R-nvim/cmp-r#6 just after I submitted this issue... Looks like it has been fixed in 7c870c8. Close now.

	nvim.getmethod <- function(fname, objclass) {
	mname <- paste0(fname, ".", objclass)
	if (exists(mname) && is.function(get(mname)))
	return(mname)
	return(fname)
	}
