listLen {Biobase} | R Documentation

## Lengths of list elements

### Description

This function returns an integer vector with the length of the elements of its argument, which is expected to be a list.

### Usage

    listLen(x)

### Arguments

`x` | A list

### Details

This function returns a vector of the same length as the list `x` containing the lengths of each element.

The current implementation is intended for lists containing vectors and the C-level length function is used to determine lenght. This means no dispatch is done for the elements of the list. If your list contains S4 objects, you should use `sapply(x, length)` instead.
