WebIn R, the pipe operator is, as you have already seen, %>%. If you're not familiar with F#, you can think of this operator as being similar to the + in a ggplot2 statement. Its function is very similar to that one that you have seen of the F# operator: it takes the output of one statement and makes it the input of the next statement. Webtherefore, develop a software package named spTimer in R. The spTimer package with its ability to ﬁt, predict and forecast using a number of Bayesian hierarchical space-time models can be used for modelling a wide variety of large space-time environmental data. This package is built in C language to be computationally eﬃcient.
