The deparse options used by default by 'deparse' and 'dput' are
c("keepNA", "keepInteger", "niceNames", "showAttributes")
but Defn.h still has
#define DEFAULTDEPARSE 1089 /* KEEPINTEGER | KEEPNA | NICE_NAMES, used for
calls */
i.e., with the SHOWATTRIBUTES bit turned off. Is that on purpose?
Note that this leads to weird things like:
> (expr <- call("is.matrix", matrix(1:4, 2L, 2L)))
is.matrix(1:4)
> eval(expr)
[1] TRUE
which can confuse anyone not paying close attention ...
