InfluxDB v2 在 R 中注释了 csv

Question

InfluxDB 和 Flux return 以带注释的 CSV 格式查询结果。我正在使用 InfluxDB v2 API 从 R studio 查询数据。如何处理我收到的带注释的 csv 格式的数据？

带注释的 csv：

有人有使用 Influx 和 R 的经验吗？

Answer 1

您可以尝试使用 InfluxDB 2.0 R client:

library(influxdbclient)

client <- InfluxDBClient$new(
    url = "http://localhost:8086",
    token = "my-token",
    org = "my-org")
                    
data <- client$query('from(bucket: "my-bucket") |> range(start: -1h)')
