partial matching in data frame subscripting
I'm not sure if the following is a bug or a feature:
> jjmat <- array(1:6, c(2,3), list(c('ABC', 'DEF'), c('xyz', 'tuv',
'qrs')))
> jjdf <- as.data.frame(jjmat)
> jjmat['AB', ]
Error: subscript out of bounds
> jjdf['AB',]
xyz tuv qrs
ABC 1 3 5
> jjmat[, 'tu']
Error: subscript out of bounds
> jjdf[, 'tu']
Error in "[.data.frame"(jjdf, , "tu") : undefined...
