Then you can avoid one level of function calls, by

Also include the output of sessionInfo(). It helps tremendously and
spares lots of second guessing.

After a lot of processing I get a matrix into M. I expected each row and

Lists are also vectors, e.g.
x - list()
is.vector(x)
[1] TRUE
y - vector(list, length=3)
str(y)
List of 3

paleotree imports phangorn which depends on Matrix, so your example
does indeed depend on Matrix.
A possible reason is that your installed Matrix was built for a
different version of R, i.e. check packageDescription(Matrix).

You could do:
library(R.utils);
value - loadToEnv(MyFile.RData)[[nameOfObject]];
It still load all of the data, but it is not kept; only the object you grab.

Can you show me how to properly memoize
An R solution is:
allocateFile - function(pathname, nbrOfBytes) {
con - file(pathname, open=wb);
on.exit(close(con));
seek(con, where=nbrOfBytes-1L, origin=start, rw=write);
writeBin(as.raw(0), con=con);
invisible(pathname);

allocateFile(foo.bin, nbrOfBytes=985403)

You need to specify that you want a binary download - make sure to
read help(download.file), particular that of argument 'mode'.
Alternatively, use downloadFile() in the R.utils package which
download as binary by default.

FYI, in R.utils (= 1.28.4) you can use listDirectory() to control how
deep the recursion goes, which would give you protection against your
problem, e.g.
R.utils::listDirectory(dir, recursive=5L)
where recursive=0L is equivalent to recursive=FALSE. Using
recursive=TRUE corresponds to

Unless you have the same issues using plain R, this sounds like a question
