Hi all,
Since I upgraded to R3.0.1 and also upgraded ffbase package, I got the
following error
when using bySum( ) funciton in ffbase.
For example:
> library(ffbase)
> bySum(iris$Sepal.Length,iris$Species)
Error in bySum(iris$Sepal.Length, iris$Species) :
REAL() can only be applied to a 'numeric', not a 'symbol'
Any idea ?
