Table summary of the data — summary

This function creates a table summary containing the min, the max, the mean, the sd (standard deviation) and n (number of value) of daily values observed from several points on a monthly basis. When the parameter by_month is FALSE the summary return is general, i.e., not on a monthly basis, so the table contains only one row with the same columns (min, max, mean, sd, and n). You can choose the amount of points to be randomly computed in the total point set.

Usage

summary_table(
  var_folder,
  sample = 5,
  percent = FALSE,
  by_month = TRUE,
  from = "2002-01-01",
  to = "2021-05-31",
  pattern = ".txt$"
)

Arguments

var_folder: Path of the input files
sample: Numeric value, informing the number of files to be used. Until the total amount is informed, the choice of points to be computed is random.
percent: When TRUE, the values passed on sample is use as as a percentage.
by_month: Either the summary should be done per month or in general. When true, the parameters from and to are ignored.
from: The first date of the series when by_month is TRUE. Remembering that when by_month is FALSE, this parameter is ignored.
to: The last date of the series when by_month is TRUE.Remembering that when by_month is FALSE, this parameter is ignored.
pattern: an optional regular expression. Only file names which match the regular expression will be returned.

Value
