Reduce will rbind 2 elements and then the result with the next element
of the list --- while do.call just applies rbind once on all elements of
the list at the same time.

‘Reduce’ uses a binary function to successively combine the
elements of a given vector and a possibly given initial va
Dear R-Experts,
using both do.call(…) and Reduce(…), I wonder about the differences of both.
Please consider the following example:
m <- matrix( 1:9, ncol=3 )
lst <- list( m, 2*m, 3*m )
rbind( lst )
# Returns
[,1] [,2] [,3]
tmp.lst Integer,9 Numeric,9 Numeric,9
do.call( 'rbind
3 matches
