Hello,

I am trying to complete a response function analysis using the command dcc
in the package 'bootRes'.
Here is my code:

DC<-read.table("Dalton.txt", header=T)
climate<-read.table("climate.txt", header=T)
dcc.DC<-dcc(DC, climate, method ="response", start = -4, end =9)

My data is formatted correctly for this analysis, with 'DC' being a data
frame that contains tree-ring chronologies and 'climate' being a data frame
with year, month, and climate parameters in columns.

I continue to get the following error:
Error in (start.year + offset):end.year : argument of length 0

Any feedback would be greatly appreciated.

Thanks,
Xanthe
