Multiplot ps time series (plugin or R script)

[volter29]

Hello everyone.
after using ISCE2, prepStackToStaMPS and StaMPS I get some .csv data.
I often use QGIS PS-Time-Series-Viewer plugin. But it would be more convenient to use a script for multiple PS selection.
Some time ago I had a script written in R that allowed to plot and make averages directly on QGIS. But after a few updates I can’t get it to work anymore. Could anyone help me out trying and fixing this script? (defo_plot it's used inside qgis)
I think these two scripts could be very useful to the whole community.
Thank you.
