[R] splitting a string into words preserving blanks (using regex)

[Mark Heckmann]

I would like to split a string into words at its blanks but also to preserve all blanks.

Example:
	c(" some    words to split ") 
should become
	c(" ", "some", "   ", "	words", " ", "to" , " ", "split", " ")

I was not able to achieve this via strsplit() .
But I am not familiar with regular expressions.
Is there an easy way to do that using e.g. regex and strsplit?

Thanks
Mark
