plot is a generic function with parameter x and dots: 

function (x, ...) 
{
    if (is.null(attr(x, "class")) && is.function(x)) {
        if ("ylab" %in% names(list(...))) 
            plot.function(x, ...)
        else plot.function(x, ylab = paste(deparse(substitute(x)), 
            "(x)"), ...)
    }
    else UseMethod("plot")
}

therefore, your method "plot.SimNI" must have an argument "x". e.g. 

plot.SimNI <- function(x, tags, closedArea, color, ...) {...}

where x is an object of class "SimNI".
