    "Latitude", "Altitude", "Satellites", "HDOP", "DateTime", "speedFilter" 
    ), row.names = c(NA, 200L), class = "data.frame")

代碼：

#install.packages("argosfilter") 
library(argosfilter) 

lizard$DateTime <- as.POSIXct(lizard$DateTime) 
lizard$Angle <- NA 
lizard$Angle[2:nrow(lizard)] <- bearingTrack(lizard$Lat, lizard$Lon) 
lizard$isContiguous <- TRUE 
lizard$isContiguous[2:nrow(lizard)] <-  (as.numeric(lizard$DateTime[2:nrow(lizard)] - lizard$DateTime[1:nrow(lizard) - 1]) == 10) 
lizard <- lizard[lizard$isContiguous, ]

對於我的大部分數據來說，這一直沒有問題，但對於一些數據，我得到以下錯誤：

Error in if (bearing > 180) bearing = bearing - 360 : missing value where TRUE/FALSE needed

我對R不太好，所以這可能是一個簡單的問題來解決，但任何關於如何解決這個問題的建議都會很棒。

'如果（軸承> 180）軸承=軸承 - 360'。應該添加導致錯誤的代碼部分。 –

一個可重複的例子會很好，所以我們可以看到你的一些數據並自己產生錯誤。看到這裏的幫助http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example – Vedda

[調試在R]（http://www.biostat.jhsph.edu/ 〜rpeng/docs/R-debug-tools.pdf）從第3部分開始，尋求像你這樣的邏輯錯誤的幫助。 –

看來您遇到Longitude和Latitude重複值的問題。這似乎現在正在工作。這些是你想要的結果嗎？

lizard$DateTime <- as.POSIXct(lizard$DateTime) 

#Remove duplicates from Longitude and Latitude columns 
lizard <- lizard[!duplicated(lizard[c("Longitude", "Latitude")]),] 

lizard$Angle[2:nrow(lizard)] <- bearingTrack(lizard$Latitude, lizard$Longitude) 
lizard$isContiguous <- TRUE 
lizard$isContiguous[2:nrow(lizard)] <-  (as.numeric(lizard$DateTime[2:nrow(lizard)] - lizard$DateTime[1:nrow(lizard) - 1]) == 10) 
lizard <- lizard[lizard$isContiguous, ]

結果

它似乎已經工作，但需要一些嘗試才能使其工作 –
