无法删除 R 中某些库的警告和消息

Question

我无法理解这些消息来自哪个库：

Warning messages:
1: In if (!(tclass %in% c("yearmon", "yearqtr"))) lubridate::tz(ret) <- tzone :
  the condition has length > 1 and only the first element will be used
2: In if (!(tclass %in% c("yearmon", "yearqtr"))) lubridate::tz(ret) <- tzone :
  the condition has length > 1 and only the first element will be used

我已经使用以下方法抑制了代码中使用的所有库的警告和消息：

suppressWarnings(suppressMessages(library(methods)))
suppressWarnings(suppressMessages(library(jsonlite)))
suppressWarnings(suppressMessages(library(tseries)))
suppressWarnings(suppressMessages(library(forecast)))
suppressWarnings(suppressMessages(library(sweep)))      # Broom tidiers for forecast pkg
suppressWarnings(suppressMessages(library(timekit)))    # Working with time series in R
suppressWarnings(suppressMessages(library(tidyquant)))  # Get's data from FRED, loads tidyverse behind the scenes
suppressWarnings(suppressMessages(library(data.table)))
suppressWarnings(suppressMessages(library(stringr)))
suppressWarnings(suppressMessages(library(httr)))

我试过抑制 lubridate 和 zoo。仍然没有变化。

请建议我应该如何抑制上述消息。

# Use as_datetime to convert from numeric time stamps to date-times

    dataframe <- dataframe %>%
        mutate(timestamp = as_datetime(timestamp))

# Setup your ts object

    ts_frequency <- 24
    start <- 1
    tk_ts_dataframe <- tk_ts(dataframe, start = start, freq = ts_frequency, silent = TRUE)

    # Arima model
    fit <- auto.arima(tk_ts_dataframe, trace = TRUE, stepwise = FALSE) 

    # Forecast
    forecast_duration <- 10
    fc <- forecast(fit, h = forecast_duration)

    # Perform sweep
    final <- sw_sweep(fc, timekit_idx = TRUE)
    final

Answer 1

它似乎不是来自任何包，而是您的 if 语句条件的逻辑。 R 试图告诉您 tclass 不是您可能怀疑或可能不怀疑的原子值，而是 list/vector 值。因此，与其查看此 vector/list 中的所有值以放入 if 条件，它只会考虑此 vector/list.

的第一个元素

解决方案：确保 tclass 是一个原子值以消除警告，如果你知道它是一个向量并且你不介意它是否使用第一个值那么你就很好。

加上一起删除警告消息，请使用 options(warn=-1)
