# processing/format.R
#
# Manages all the format problem of data and info. Mainly problem of
# input and output of the 'StatsAnalysisTrend' package. It also allows
# to join different selections of station and to gets exact period of
# trend analysis.
# Usefull library
library(dplyr)
## 1. INPUT
### 1.1. Preparation
# Prepares the data in order to have a list of a data tibble with
# date, group and flow column and a info tibble with the station code
# and group column to fit the entry of the 'extract.Var' function in
# the 'StatsAnalysisTrend' package
prepare = function(df_data, colnamegroup=NULL) {
# Forces the column name to group to be a vector
colnamegroup = c(colnamegroup)
# Converts it to index of the column to group
colindgroup = which(colnames(df_data) == colnamegroup)
# Groups the data by those indexes
df_data = group_by_at(df_data, colindgroup)
# Creates a new tibble of data with a group column
data = tibble(Date=df_data$Date,
group=group_indices(df_data),
Qm3s=df_data$Qm3s)
# Gets the different value of the group
Gkey = group_keys(df_data)
# Creates a new tibble of info of the group
info = bind_cols(group=seq(1:nrow(Gkey)),
Gkey)
# Stores data and info tibble as a list that match the entry of
# the 'extract.Var' function
res = list(data=data, info=info)
return (res)
}
### 1.2. Re-preparation
# Re-prepares the data in outing of the 'extract.Var' function in
# the 'StatsAnalysisTrend' package in order to fit again to the
