Dear All, Recently I start to learn how to use the MCRestimate package to gauge the MCR values. I just simply carried out the example offered in the package: ------------------------------------------- library(golubEsets) data(Golub_Test) G2 <- Golub_Test[1:500,] result <- MCRestimate(G2, "ALL.AML", classification.fun="RF.wrap", cross.outer=4, cross.repeat=3) result if (interactive()) { x11(width=9, height=4)} plot(result) -------------------------------------------- And then I did: > result$parameter list() According to the manual, this list should not be "NULL" and include the estimated "best" parameters for each cross-validation part. I would be deeply grateful if you can help me to figure it out. Regards, ZHENG (ALEX) FU [[alternative HTML version deleted]]
