Can you try reinstalling the package? I've overhauled the soccerSpokes() function and it seems to work now, at least for me.

davidfombella commented 6 years ago

Yes, now works. Please I send you a mail , trying to check if given x,y,time utc , you can help me to calculate speed,angle, acceleration to be able to test soccerSpokes and soccerFlow, it is raw data from stadium cameras.

Now error is on this file Error in .install_package_code_files(".", instdir) : files in 'Collate' field missing from 'C:/Users/dpomb/AppData/Local/Temp/RtmpWisOsT/devtools31a83d191083/JoGall-soccermatics-ff94e4e/R': pipe.R ERROR: unable to collate and parse R files for package 'soccermatics'

JoGall commented 6 years ago

The issue with pipe.R should be fixed now if you reinstall.

As for extracting speed and heading angle from raw x,y,t-data, see this gist for an example.

Speed is just the Pythogarian distance between successive x,y-points divided by the time interval, and heading angle can be calculated using atan2.

I may add a function to the package for calculating these soon.

On soccer spokes fails, since I have a time column Error in assert_all_white_list(data) : Column utc is of unsupported class POSIXlt/POSIXt

JoGall commented 6 years ago

Have you tried excluding the time column from your input data? i.e. soccerSpokes(data[,c("x", "y")])

The function shouldn't be handling time variables anyway so I'll update it soon.
