apply on logical data frame together with all (PR#6560

Wrap your data frame in data.matrix() and you should be fine; e.g.,

  apply(data.matrix(df), 1, all)

Don't think this qualifies as bug...

I have a data frame with some columns being logical.
I wanted to calculate a column that is an AND combination of 
the other logical
columns.
I tried to use
  apply(df,1,all)
It did not work because of the implicit string conversion.
So I made the functions
  All<-function(...) all(as.logical(...))#because all cannot 
be used with apply
  Any<-function(...) any(as.logical(...))#because any cannot 
be used with apply
Now 
  apply(df,1,All)
seemed to work,
but produced some NAs where there was no reason for them.
I debugged apply and found that some logical values are 
transformed to " TRUE"
instead of "TRUE". I did not follow that up closer. Instead I 
worked around it
by doing the string conversion myself and then call apply(dfc,1,All)
