How to select dropdown box using Rselenium?

问题:

I am interested in the stats in the English Premier League. So, I try to get data from this official site https://www.premierleague.com/stats/top/players/total_pass

I am using R and RSelenium package.

library(rvest) library(httr) library(RSelenium)  remDr % html_nodes("strong") %>% html_text()

But I got the some problems. There are some categories of data such as seasons, positions, clubs and so on.

So, I thought that I can get data based on these categories. But I did not know how to select specific things in the dropdown box using Rselenium in this site.

I thought that filenElement and clickElement are useful functions for this. However, I do not know how I should handle these functions to select specific conditions such as 2016/17 season and Goalkeeper position.

Please give me an advice for this.

Using the following code I was able to get the browser to select the 2014/15 season. You will need to inspect the contents of the various drop-downs and expand this as required.
