Perhaps this is the intended behavior, but I discovered that unsplit
throws an error when it tries to set rownames of a variable that has no
dimension. This occurs when unsplit is passed a list of data.frames
that have only a single column.
An example:
df <- data.frame(letters[seq(25)])
fac <- rep(seq(5), 5)
unsplit(split(df, fac), fac)
For reference, I'm using R version 2.9.0 (2009-04-17), subversion
revision 48333, on Ubuntu 8.10.
That's a bug. The line
x <- value[[1L]][rep(NA, len), ]
should be
x <- value[[1L]][rep(NA, len), , drop=FALSE]
