Subject: Convert COLON separated format

I have a bunch of data sets that were created for the libsvm tool.  They are in "colon separated sparse format".

i.e.

1  5:1  27:3  345:10

Is a row with the label of "1" and only has values in columns 5, 27, and 345.

I want to read these into a data.frame in R.  

Is there a simple way to do this?
