ho trovato il mio Google Cronologia delle posizioni inCome posso leggere il mio Google Location History in R
https://maps.google.co.uk/locationhistory/b/0/?hl=en-GB
Ho poi scaricato il file delle KML
ho installato rgdal
correttamente, ma sono in grado di leggere il file
ho messo il nome del file e lo strato di nome come da https://gis.stackexchange.com/questions/58131/how-to-efficiently-read-a-kml-file-into-r
hist = readOGR(dsn="/home/ajay/Desktop/history-05-04-2015",layer="Location history from 05/05/2015 to 06/04/2015")
.515.053.691,36321 milioni
questo è il modo di file assomiglia
