Cumulative max for each column; each successive element of the output is the cumulative max from the initial element, ignoring NAs.
Cumulative min for each column; each successive element of the output is the cumulative min from the initial element, ignoring NAs.
Cumulative min for each column; each successive element of the output is the cumulative min from the initial element, ignoring NAs.
Cumulative product for each column; each successive element of the output is the cumulative product from the initial element, ignoring NAs.
Cumulative product for each column; each successive element of the output is the cumulative product from the initial element, ignoring NAs.
Cumulative sum for each column; each successive element of the output is the cumulative sum from the initial element, ignoring NAs.
Cumulative sum for each column; each successive element of the output is the cumulative sum from the initial element, ignoring NAs.
Sum of the natural logs of the elements of each column, ignoring NA values.
Sum of the natural logs of the elements of each column, ignoring NA values.
