graph_trend function

Plot of original and smoothed time series.

It plots the univariate or bivariate. This function is not intended for users but to be called by trend_estimate.

graph_trend(dat, N, tau, dvar, label = NULL, jump = 1:N,
  bands = TRUE, las, bivariate = TRUE)

Arguments

• dat: is a 2x2 covariace matrix
• N: the number of observations
• tau: the smoothed time series
• dvar: the estimated variance for tau
• label: the vectors of caracters associated to the time points to appear in the axis
• jump: if label is too long, jump thin them on the axis
• bands: is TRUE to draw the approximately 95% confidence bands around tau
• las: is 1 and 2 if the asis should appear vertical and horizontal, respectively
• bivariate: is FALSE if dat is a univariate time series

Returns

The empirical correlation fo the two series
