Dear collegues, I am using S-Plus for many years and is thinking of moving to R. In the FAQ I did not manage to find an answer to the following questions: Is it easy to move and transform functions, written under S-plus to functions under R? Furthermore, S-Plus has interesting functions to deal with regular and irregular times series (rts, its, ts.plot, ts.lines, ts.points, aggregate.rts, etc..) and the possibility to plot, on the same graphic, regular time series with different frequencies and even irregular time series. Is it still possible in R? Thanks in advance for your answers.
