and also spell "select" correctly in y <- subset(data,select=10) or, more simply, specify X <- data[, -10] y <- data[, 10] It is not clear if the function you are using requires X to be a matrix, like a model matrix, or a data frame. If it expects a matrix use X <- data.matrix(data[, -10]) >> here data is of 60 records and 10 attributes.
