```julia
using SingularSpectrumAnalysis, Plots
# generate some data
L = 20 # Window length
K = 100
N = K*L; # number of datapoints
t = 1:N; # Time vector
T = 20; # period of main oscillation
y = sin.(2pi/T*t); # Signal
y .+= (0.5sin.(2pi/T*4*t)).^2 # Add another frequency
e = 0.1randn(N); # Add some noise
yn = y+e;
# plot(ys)
yt, ys = analyze(yn, L, robust=true) # trend and seasonal components
plot(yt, lab="Trend")
plot!(ys, lab="Season")

It’s generally not considered appropriate to tag package authors you find on GitHub when you post questions on Discourse - if you think there’s an actual issue with a package, file an issue on the GitHub repo.
You seem to be running into trouble with your GR backend. Run `] build GR` and try again.
