Hi all, I am trying to calculating derivatives for vectors using R. I have a numerical vector, which is in time series manner and contains "NA"s. I want to know the changing rate throughout the whole time range. I am wondering if there is function in R can do this. In R references I only found functions for calculating derivatives of expressions.
For example, vectors like this x<-c(0.997549748, 0.98039798, 0.963097713, 0.930576181, 0.907484407, 0.875705376, 0.826477576, NA, 0.772794773) Thanks in advance.
