Hmm…Chuck’s solution may actually be problematic because there are several
entries which at the deepest level are called “sha”, but that should not be
included, such as:
input[[67]]$content[[1]]$commit$tree$sha
and
input[[67]]$content[[1]]$parents[[1]]$sha
it’s only the “sha” that fit the following subsetting pattern that should be
included:
input[[i]]$content[[1]]$sha[1]
This should be straightforward. Look at what grepl() is doing.
And look at what names(unlist(input)) yields.
You can either write a regular expression to handle this (perhaps
"content.sha$") or write other grepl() expressions to select (or get rid
of) the desired (or unwanted) pattern.
See ?grepl and the page on regular expression referenced there.
HTH,
