I think not. The first *five* lines are

    if (!is.na(pmatch(method, "euclidian")))

        method <- "euclidean"
    METHODS <- c("euclidean", "maximum", "manhattan", "canberra",

        "binary", "minkowski")
    method <- pmatch(method, METHODS)

so what happens is that if you enter "euclidian" (which I gather is an uncommon but valid spelling) you get the same result as with "euclidean".
