Hi All, Could you please help with the error I get from the following codes?> Library(cluster)> data(iris)> bc1 <- bclust(iris[,2:5], 3, base.method="clara", base.centers=5)Then I got: "Committee Member: 1(1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) Error in bclust(iris[, 2:5], 3, base.method = "clara", base.centers = 5): Could not find valid cluster solution in 20 replications" I don't quite understand what the error means here and how to fix it? Thank you! [[alternative HTML version deleted]]

The cluster function must accept an argument "centers" in order to work.
