hi
I have a wind dataset and I want to analze its spectrum with
the x-axis and y-axis in log .But I found that
when I set log="dB" in spectrum as shown below,what I can get
is a figure by log y-axis.
How could I get a log-axis figure both in x-axis and y-axis ?
thank you .

yylab<-c("Wind Spectrum(db) ")
YY=c(-40,40)
spectrum(ww_spec,log = "dB",ylim=YY,main=maininfo,ylab=yylab)
