r - Cannot access column of data frame -

-

When I see the result, I have some data in the result of the 3-column data frame: 

  results TIMESTAMP SYMBOL_NAME "t.price" 1 2014-10-17 14:00:00 GOOG 400.25

Notifications around t.price columns

< P> When I reach the t.price column, as it comes back. 

  result $ t.price null

When I

P> 
  name (result)  < / Pre> 
 see me 
 
  [1] "TIMESTAMP" "SYMBOL_NAME" "\" t.PRICE can you tell me what is happening and why it looks or How i t Can I use the value?   
 
 
 Try this:  
  names (results) & lt; - make.names (name (result))  
 
 This is the same function that is applied when  read.table  and its lineage is used .
