How can I find the percentage of Males with a Height of over 60?

how can I find the percentage of Females with a Height of over 60?
R-help expects you to read the introductory materials offered at CRAN,
of which there are quite a few examples, before posting
questions, ... especially when they look like homework.
Here's what you should do: Get this into R using the read functions,
read the Posting Guide to see one method of creating reproducible
versions of R objects or look at the dput function for another method.
Then and only then post your homework question as reprocucible R code
and further hints will perhaps be offered.
