[R] substitute

[Wladimir Eremeev]

Dear r-help,

  I have troubles with 'substitute'.
  I have the data frame with vectors data$area.0, data$area.20, etc...
  Command
  
  substitute(data$area.lon,list(lon=20))

  returns

  data$area.lon

  but is expected to return data$area.20

  Where did I do mistakes?
