[R] Setting Number of Displayed Digits

[arun]

HI,
formatC() may work for you.
 summary(x,digits=5)
#may not work here.

I tried this within a list.  For some of the list members, this is not working.
summary(list12[[5]],digits=max(7))
  # Min. 1st Qu.  Median    Mean 3rd Qu.    Max. 
  #  1.0     1.0     2.5     3.2     5.0     7.0 

 formatC(summary(list12[[5]]),format="f",digits=7)
#     Min.   1st Qu.    Median      Mean   3rd Qu.      Max. 
#1.0000000 1.0000000 2.5000000 3.2000000 5.0000000 7.0000000 

A.K.

Subject: [R] Setting Number of Displayed Digits

  Some chemicals have concentrations at or below the method detection limit
(MDL; 'less-thans') of 0.005 mg/L. When I look at the data frame that is how
the concentration is displayed. But, when I ask for a summary() of that data
frame column only 0 is displayed.

  How can I adjust the number of digits displayed by functions such as
summary()?
