Dear R experts, I have used waveletcomp package of R and was trying to get the dates formatted as month & year but get below error while trying it with the example provided in http://www.hs-stat.com/projects/WaveletComp/WaveletComp_guided_tour.pdf Kindly help me with the dateformat so that I can get %Y-%m as xaxis label data(FXtrade.transactions) my.data.a = FXtrade.transactions[FXtrade.transactions$active == T, ] my.w.a = analyze.wavelet( + my.data.a, "transactions", + loess.span = 0.0, # no detrending required + dt = 1/(12*24), + # one day has 12*24 5-minute time slots + dj = 1/250, + # resolution along period axis + lowerPeriod = 1/8, # lowest period of interest: 3 hours + make.pval = T, + # draws white lines indicating significance + n.sim = 10)
wt.image(my.w.a, n.levels = 250, periodlab = "periods (days)", + legend.params = list(lab = "wavelet power levels"), + show.date = T, date.format = "%Y %m", timelab = "") Error in plot.window(...) : need finite 'xlim' values In addition: Warning messages: 1: In min(x) : no non-missing arguments to min; returning Inf 2: In max(x) : no non-missing arguments to max; returning -In with best regards Sudheer ********************************************************************************** Dr. Sudheer Joseph Scientist, INCOIS, MoES, Govt. of India.
