Abstract

Read local weather data with a longer term aim towards correlating these data with environmental data logged inside the museum.

Local Temperature

First call the necessary libraries.

# Knitr options
knitr::opts_chunk$set(
  echo = FALSE,
  message = FALSE,
  warning = FALSE
  )


library(dplyr)
library(riem)
library(xts)
library(dygraphs)

Then request data and evaluate results (Table 1).

Table 1:

The first rows of station LRU

ABCDEFGHIJ0123456789

station <chr>	valid <dttm>	lon <dbl>	lat <dbl>	tmpf <dbl>	dwpf <dbl>	relh <dbl>	drct <dbl>	sknt <dbl>

LRU	2020-01-01 01:15:00	-106.922	32.2894	36.9	14.0	38.59	340	6
LRU	2020-01-01 01:35:00	-106.922	32.2894	38.1	14.9	38.29	340	7
LRU	2020-01-01 01:55:00	-106.922	32.2894	37.0	15.3	40.69	340	6

To use the dygraphs library, convert the data to a time series. Here, I use xts to create time series objects for temperature and relative humidity which are variables recorded inside at the museum. Then we take the two time series and cbind them into a single object.

This is then displayed by calling the dygraph function and applying minimal styling arguments.
