Unable to remove warnings and messages for some library in R

问题

I could not understand from which library these messages are coming from:

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

I have already suppressed warnings and messages of all the libraries used in my code using:

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)))

I've tried suppressing for lubridate and zoo. Still no change.

Please suggest what should I do to suppress above mentioned messages.

Code :

# 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

回答1:

It does not appear to be coming from any package but instead the logic of your if statement condition. R is trying to tell you that tclass is not an atomic value as you may or may not have suspected but instead a list/vector of values. So instead of looking at all the values in this vector/list to put into the if condition, it will only consider the first element of this vector/list.

Solution: Make sure tclass is an atomic value to get rid of the warning, if you know that it is a vector and you don't mind if it uses the first value then you're good.

Plus to get rid of warning messages all together use options(warn=-1)
