You re missing  s in the last two terms of your expression  so R is interpreting  e g   0 207  log DIAM93   2 as an attempt to call a function named 0 207     For example   gt  1   2  3   1  7  gt  1   2  3    Error  attempt to apply non-function  Your  unreproducible  expression should read  censusdata 20 AGB93   WD   exp -1 239   1 980   log  DIAM93                                   0 207   log DIAM93   2  -                               0 0281  log DIAM93   3   Mathematica is the only computer system I know of that allows juxtaposition to be used for multiplication
