Usage
selectSome(obj, maxToShow=5)
Arguments
obj
A vector.
maxToShow
The number of elements (including "...") to render.
Details

This function can be used in 'show' methods to give users exemplars of the tokens used in a vector. For example, an ExpressionSet built from a yeast experiment might have features enumerated using systematic gene names (e.g., YPR181C) or standard gene names (e.g., SEC23). The show method for ExpressionSet uses selectSome to alert the user to the tokens used, and thereby to indicate what vocabulary must be understood to work with the feature names.

Value

A string vector with at most maxToShow plus 1 elements, where an ellipsis ("...") is included to indicate incompleteness of the excerpt.
