You appear to be confusing source code formatting with output formatting. The
internal representation of a numeric value has no notion of the number of
decimals that were used to enter it into memory from source code.
The question was about matrices, not data frames or data tables. While faster
than Reduce, the conversions still make it over twice as slow as Rui's answer.

Someone might respond here anyway, but I think this is more of an R-devel
question.
Anyway, as long as the package file after installation has appropriate file
names for where it is installed, what does it matter what is in the files

For future reference, this kind of question should usually be accompanied by
information about your OS such as the sessionInfo function returns... but in
this case just read about the wait argument to ?system2.

Have you ever used the seq_along() function?
If you want to delegate the decision of how many elements you want to process
to some earlier point in your (or someone else's) code, then the most logical
way to create a result vector that is the same size as some input vector, even
if that vector

! is a logical operator... it means "not". When you write
lidx <- seq_along( mtcars[[ 1 ]] ) %in% train_indices
you end up with a vector of logical values for which ! makes sense. Since R
supports logical indexing this can be a very convenient way to select one group
or the other.
