Return a discrete representation of y by transforming it into an unordered categorical variable which indicates whether a value went up, down, or remained the same relative to the previous value.
ts_symbolic(y, keepNA = TRUE, usePlateaus = FALSE, doPlot = FALSE)Numeric vector or matrix to be discretised. Will return attributes with labels for each column in the matrix.
If TRUE, any NA values will first be removed and later re-inserted into the discretised time series. (default = TRUE)
Give consecutive "same" values after "peak" or "trough" a "peak" or "trough" label instrad of "same". (default = FALSE)
Create a plot of the symbolized series. (default = FALSE))
A symbolic version of y
