This function is the same as strsplit except that the output value is a matrix instead of a list.
The first column of the matrix contains the first component from each element of x, the second column contains the second components etc.
The number of columns is equal to the maximum number of components for any element of x.
The motivation for this function in the limma package is handle input columns which are composites of two or more annotation fields.
A list containing components
Name |
character vector of the same length as |
Annotation |
