Interesting question! If I ever get some time to dust this piece off, might try to revisit and answer your question. Thanks for resurfacing this post!

That’s an incomplete address. Also, I am no longer maintaining this package unfortunately. Sorry but I won’t be able to help

Thanks for the kind words James! Glad to hear it helped.

So far no takers, but hopefully someone picks it up. The challenge will be managing the increasing aggressive blocking of web scraping of some of the sites worldfootballR was getting data from

Leaderboard - Squiggle

Huge thanks to Max @squiggle.au for yet another massive year's effort! He puts in a tonne of thankless work so some of us footy modellers can test our models against each other. Was pretty stoked to take out the accuracy award and come second in the margin this season squiggle.com.au/leaderboard/

Hey mate, it will continue for now, but they’ve made some backend changes so I won’t have a fix for that until a week or two in to the season unfortunately

Love hearing these stories Chris and it’s no doubt what kept us going for so long!

Retiring from maintaining `worldfootballR` Β· Issue #454 Β· JaseZiv/worldfootballR I have no spare capacity to continue to maintain this library so I will be taking a step back. Happy for anyone to take this as the bones of a potential version 2 of it and make it their own. Thank...

To all the users of {worldfootballR} and the amazing connections I’ve created through that vehicle, I’m sorry to say that {worldfootballR} will no longer be maintained. I’m incredibly proud of it and incredibly thankful all the support I’ve received over the years! github.com/JaseZiv/worl...

Will try to look into it

What version of worldfootballR are you running?

Fbref are aggressively blocking scraping activity now… nothing we can do unfortunately. Need to respect their terms.

The dates issue should now be fixed in version 0.6.8.0001. Install the latest version from github. Reach out if there's any issues.

23.08.2025 12:30 πŸ‘ 0 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

Looks like a bug with some of the date fields being wiped due to TM displaying their dates differently. Will have a fix over the weekend. Sorry for the inconvenience

I will however look into tm_player_bio() hopefully tomorrow to see what’s happened there

Hey Chris, no it’s not you… TM have become a bit more aggressive in blocking scraping activity so it’s likely that… I’ve found creating loops and increasing time between player page loads to 15 seconds goes some way to address this, but it’s also not perfect. Reach out if you need a working example

So well deserved Max!

If you’re getting that error, you’re likely in their β€˜dog house’ for a period of time, due to excessive page loads. I think historically this might have been 24 hours. Wait it out.

That certainly could be interesting. I suppose my follow up question is how to estimate alpha? 'General good kick' seems like you'd also need to control for a number of factors, which could also lead to small sample sizes?

22.06.2025 11:51 πŸ‘ 1 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

Have also thought about the effectiveness of this but small sample size keeps me from doing any heavy lifting

Haven't posted an update for a while but given the angst getting player valuations are causing, we've pushed an update to version 0.6.8, allowing users the ability to loop through each team instead to fix issues a little easier as they arise #worldfootballR

Have hacked something together (not yet ready to be pushed to a version update of worldfootballR) but could share some data from this season... DM me where you want me to send the data and whether .csv or .rds
