Arguments

df

Date frame with data in wide format.
dates

Name of column in `df` which contains dates.
series

convert.to

Granularity of x axis. One of c('weeks', 'months', 'quarters', 'years'). Default value is 'months'.

Data frames in returned list consist of columns: * containing numeric values from 0 to 100 defining the percentage of distance in one time interval of the point (x - coordinattes of the point) * containing the value of a point (y - coordinates of the point) * containing the time interval of the value

Examples

df <- data.frame(
    dates = as.Date(c('2021-07-12', '2021-06-18', '2021-05-12')),
    val1 = c(1.5, 1.2, 2.1),
    val2 = c(0.9, 3.2, 1.1))
parse_time_series(df, 'dates', c('val1', 'val2'))
