WebThe rowwise () approach will work for any summary function. But if you need greater speed, it’s worth looking for a built-in row-wise variant of your summary function. These are more efficient because they operate on the data frame as whole; they don’t split it into rows, compute the summary, and then join the results back together again. WebIf scale is a numeric-alike vector with length equal to the number of columns of x, then each column of x is divided by the corresponding value from scale. If scale is TRUE then scaling is done by dividing the (centered) columns of x by their standard deviations if center is TRUE, and the root mean square otherwise. If scale is FALSE, no ...
