   29 sie 2019 · Here is a solution using data.table. It (i) identifies numeric columns and (ii) obtains the mean of the absolute value of each numeric column. Data. dt = data.table( num1 = rnorm(100), num2 = rnorm(100), strv = sample(LETTERS, 100, replace = T) ) Code. numcols = colnames(dt)[unlist(lapply(dt, is.numeric))] # Which columns are numeric?
