waveThresh plot axis
Dear,
I am using WaveTresh for Haar Wavelets. It works all fine exept when I
want to adjust the axis on the wavelet coefficient plot:
input: wlh_ponds<-wd(input_waves[,1], family="DaubExPhase",filter.number=1)
plot: plot(wlh_ponds,scaling="by.level")
My problem is twofold=
-I want the original x-axis of the data on that plot, not 1/2 of the
axis. This would make my plot more clear for comparison with the
original data series.
-I want to cut of a part of the graph b...

Error:Data is not atomic
Hi experts,
I want to user haar wavelet transform. If I am using this simple command,
it works nice:
k<-c(1,2,3,4,5,6,7,8)
ywd<-wd(k,filter.number=1,family="DaubExPhase")
but if the K is a list like this:
*[[1]]*
*[1] 401*
*
*
*[[2]]*
*[1] 481*
*
*
*[[3]]*
*[1] 480*
*
*
*[[4]]*
*[1] 482*
*
*
*[[5]]*
*[1] 395*
*...*
*
*
it doesnt work and I get this error:
Error in wd(k, filter.number = 1, family = "DaubExPhase") :
* Data is not atomic*
*
*
how c...
