我不知道为什么在此错误代码中提到df，而103.78751是行而不是列。任何帮助将非常感激。
如果您阅读?df2move，则期望x，y和time列是该列的名称，而不是值。同样，time列需要属于POSIXct类。所以尝试：
df$timestamp <- as.POSIXct(df$timestamp, format = '%d/%m/%y %H:%M', tz='Singapore')
m <- moveVis::df2move(df, x = 'location.long', y= 'location.lat',
time= 'timestamp',
proj ="+proj=longlat +datum=WGS84 +no_defs",
removeDuplicatedTimestamps=T)
