Hello, My name is Katerina, i am new to R and i am working with the ETAS package. My goal is to fit the spatiotemporal etas model to an aftershock sequence ( atach file example.csv).I have installed the packages: spatstat, SAPP and ETAS. By reading the ETAS package manual i saw the data must be in class ppx. Could you please help me on how to convert my data (example.csv) into class ppx ? Thank you in advance,Katerina
