In kvantas/emyweather: Open climatic data from the Greek National Meteorological Service

knitr::opts_chunk$set(
  collapse = TRUE,
  comment = "#>"
)

With this vignette the raw data that have been downloaded from www.emy.gr are transformed from a list of csv files to a tidy data frame, using the function emy_create.

# the data from emy are downloaded to the folder ./raw-data/emy the following
# command will create a list of directories created in that folder
dir_names <- list.files('./emy', full.names = TRUE)

# these directories have the raw data from every station
dir_names

The following code will create a data frame with the available meteorological data.

source(file = "./emy_create.R")
emy_data <- emy_create(dir_names)

The variables in the created data frame are:

names(emy_data)

and some basic statistic values:

summary(emy_data)

Before the use of these data the cleaning from errors is a necessity. The maximum precipitation of 555 mm is obviously an error or a code.

emy_data <- tibble::as.tibble(emy_data)
devtools::use_data(emy_data, overwrite = TRUE)
