[R] interpolation function

[Adaikalavan Ramasamy]

I do not understand your question. If this was not a sparse matrix, then
I would have asked you refer into the missing value literature. Even
there, people generally remove any columns/rows that have too many
missing values to avoid unreliable results. 

And since this is a sparse matrix, you are going to have too many
missing values on all rows and columns. I could be wrong but if I am,
someone will tell me that soon enough.

Regards, Adai
