how to separate stuck row elements?

Hi,

I was wondering if it's possible to separate elements in multiple rows  
that actually should appear in different columns. I have a file where  
in certain lines there are elements not separated, and they certainly  
should appear in different columns (an example of the file is  
attached). The point is that I do not want to manually add a space in  
the txt file, however, I did not manage to do it automatically in R...

Thanks in advance for any insight.

Jaime
