Display time series and flag them in R Shiny App

I need a small extension of a R Shiny app or a stand alone version based on the style I have: [[login to view URL]\_dial/] Duty book: My R Shiny App displays the **mean** of several time series via ggplot. The format of the time series comes from a data frame carrying the time in the first column and several time series in all the other columns (see example attached). I would like to adjust this Shiny app or have a stand alone one based on the one I have (what is more convenient for you). 1. The app displays a time series as a whole (one after another see 2) with adjustable ymin and ymax in a form field. ymin could also be negative. Defaults could be set, graph updates when changed. Series can be very long! 2. The app has two buttons - »previous« and »next« - to click through each time series column which is then displayed on screen (together with its column name) 3. The app provides two radio buttons: »keep« and »delete«. This keep/delete buttons »flag« the displayed time series displayed being »usable« or »unusable«. How it is flagged should be shown somehow/somewhere next to the series (or you display the line chart in red versus blue in red or something like that, …) 4. Finally the app provides a data frame with all column names (= time series) and their flag being »usable«/»unusable«. Default is »usable«. I am not sure how to provide the resulting data frame. You might have a good idea? Make a csv to download? Just provide a ne data frame object?
