我正在尝试使用 googleway 库从 googlemaps 中提取数据。我在应用 R 函数中使用了 Google Elevation API


Requests <- apply(df, 1, function(x){

                     google_elevation(df_locations =x[c("lat", "lon")],
                     location_type = "individual",
                     key = key,
                     simplify = TRUE)
})

但我收到以下错误

df_locations should be a data.frame containing at least two columns of lat and lon coordinates

在函数中选择 df 列我做错了什么?

谢谢
