Dear Diethelm and Core team, 

I am using your fExtremes package and specifically the hill.Plot and
shaparmHill function to fit a vector of (non-negative) wealth values.

Hill.plot works perfectly, but when I try to use shaparmHill I get the
following message:

 

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 -Inf

 

I was using simply:

x<-read.table("C:/Documents and
Settings/teytelbo/Desktop/test_us_nw2.dat", header=TRUE)

x<-x[,2]

x<-x[x>0]

hillPlot.summary(x, plottype="alpha")

shaparmHill(x, p = 0.05, xiRange = NULL,doplot = TRUE, plottype =
c("both")

 

In the end I am hoping to get an optimal parameter to fit the
distribution.

 

I look forward to hearing from you.

Best, 

Alex
