title: Taylor Diagram in R - averaging daily values
body: <p>I'm a beginner at R and am trying to make Taylor diagrams to compare model and observational data. I have two data frames with daily temperature averages for model and obs data, but with different time ranges, so they have different lengths. I want to create a Taylor diagram with monthly averages drawn from the daily averages (so there will be 12 points for model and obs data on the Taylor Diagram).</p>
  <p>I'm struggling to do this (I've looked into both openair and plotrix packages but am very confused). I tried creating a monthly average dataset and making Taylor diagrams off of these, but the standard deviation values with the openair TaylorDiagram function are drawn from the monthly averages, whereas I would like the SD to be drawn from the daily data instead.</p>
  <p>Is there a way to input these two datasets of different lengths/time frames, and plot Taylor diagrams where monthly averages are visualized along with the SD capturing the variability in the daily averages?</p>
